When we talk about fiberglass, we actually mean a composite material where glass fibers and plastic are mixed together. Composites are produced by combining several substances into a composite material. The choice of substances is based on the properties we want the material to have. The substances will work together and to give the final composite material the best possible performance. The mix gives us the opportunity to customize the material with the benefits we want.<\/p>\n\n\n\n<div style=\"height:57px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr

There are many different types of resins used in the production of composites. Most of our products are made with polyester, vinyl ester or phenol.<\/p>\n\n\n\n<div class=\"wp-block-columns alignfull is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/glassfiber.no\/wp-content\/uploads\/Glassfiberlistepunkt.svg\" alt=\"\" class=\"wp-image-495\" style=\"aspect-ratio:0.9930230136415703;object-fit:cover;width:86px;height:auto\"\/><\/figure>\n<\/div>\n\n\n<h4 class=\"wp-block-heading has-text-align-center\">Polyester<\/h4>\n\n\n\n<div style=\"height:19px;width:9px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-group is-nowrap is-layout-flex wp-container-core-group-is-layout-8f761849 wp-block-group-is-layout-flex\">\n<p class=\"has-text-align-center wp-block-paragraph\">Polyester is the most commonly used type of resin. It is a versatile and affordable material with a number of advantages, and works well in combination with glass fibres. The flexibility and properties of polyester make it suitable for most applications.

The fiberglass delivers a low flame spread score of 15 and a smoke development value of 400-450.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-text-color has-luminous-vivid-amber-color has-alpha-channel-opacity has-luminous-vivid-amber-background-color has-background\"\/>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h1 class=\"wp-block-heading has-text-align-center has-large-font-size\"><strong>FLEXIBLE<\/strong><\/h1>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Flexibility is yet another advantage we can add to the list of good reasons to choose fiberglass. Fiberglass is still associated with old boats, but the material is and can be so much more. The material itself is versatile, elastic but at the same time durable. Fiberglass can be adapted to most applications, and can be shaped into countless different types of profiles that will fit any specification. It is the combination of all the properties that makes fiberglass a sought-after solution. The properties of the material mean that fiberglass can be used as an alternative in a number of areas where other traditional materials are not sufficient.<\/p>\n\n\n\n<div class=\"wp-block-columns

The openings allow light, air and water to pass through easily, which is important for applications where good ventilation and drainage are required. Gratings are often used in industrial areas, on bridges and in staircases.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The gratings we sell are made of fiberglass and are most often used for walkways and platforms. The fiberglass material means that the gratings are light, yet strong. This makes them easy to work with and adapt on site. The gratings are basically&nbsp;<a href=\"https:\/\/glassfiber.no\/en\/professional-articles\/hva-er-korrosjon\/\">corrosion-resistant<\/a>&nbsp;against external environments and is therefore particularly suitable for environments exposed to corrosion.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"980\" height=\"654\" src=\"https:\/\/glassfiber.no\/wp-content\/uploads\/Salmon-evolution-tank-2-980x654-1.webp\" alt=\"\" class=\"wp-image-2023\" srcset=\"https:\/\/glassfiber.no\/wp-content\/uploads\/Salmon-evolution-tank-2-980x654-1.webp 980w, https:\/\/glassfiber.no\/wp-content\/uploads\/Salmon-evolution-tank-2-980x654-1-768x513.webp 768w\" sizes=\"auto, (max-width: 980px) 100vw, 980px\" \/><figcaption class=\"wp-element-caption\"><em>Wire mesh gratings used as walkways on land-based fish farming facilities.<\/em><\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1366\" height=\"911\" src=\"https:\/\/glassfiber.no\/wp-content\/uploads\/DSC03961-1366x911.jpg\" alt=\"\" class=\"wp-image-2024\" srcset=\"https:\/\/glassfiber.no\/wp-content\/uploads\/DSC03961-1366x911.jpg 1366w, https:\/\/glassfiber.no\/wp-content\/uploads\/DSC03961-768x512.jpg 768w, https:\/\/glassfiber.no\/wp-content\/uploads\/DSC03961-scaled.jpg 1920w\" sizes=\"auto, (max-width: 1366px) 100vw, 1366px\" \/><figcaption class=\"wp-element-caption\"><em>Gratings used as stair treads.<\/em><\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1366\" height=\"911\" src=\"https:\/\/glassfiber.no\/wp-content\/uploads\/Syrekammer-scaled-1-1366x911.webp\" alt=\"\" class=\"wp-image-2025\" srcset=\"https:\/\/glassfiber.no\/wp-content\/uploads\/Syrekammer-scaled-1-1366x911.webp 1366w, https:\/\/glassfiber.no\/wp-content\/uploads\/Syrekammer-scaled-1-768x512.webp 768w\" sizes=\"auto, (max-width: 1366px) 100vw, 1366px\" \/><figcaption class=\"wp-element-caption\"><em>Our thinnest wire mesh used to make a cage used in acid baths.<\/em><\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>The difference in the gratings<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">There are several ways we differentiate our gratings, based on how they are manufactured, what components they are made of and what applications they are intended for.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Production method<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Let&#039;s look at the production method.<br>We stock goods produced using two different production methods:<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1366\" height=\"1025\" src=\"https:\/\/glassfiber.no\/wp-content\/uploads\/37cd1a71-aec0-49d8-af10-c7132d09566e-1366x1025.png\" alt=\"\" class=\"wp-image-1555\" srcset=\"https:\/\/glassfiber.no\/wp-content\/uploads\/37cd1a71-aec0-49d8-af10-c7132d09566e-1366x1025.png 1366w, https:\/\/glassfiber.no\/wp-content\/uploads\/37cd1a71-aec0-49d8-af10-c7132d09566e-768x576.png 768w, https:\/\/glassfiber.no\/wp-content\/uploads\/37cd1a71-aec0-49d8-af10-c7132d09566e.png 1920w\" sizes=\"auto, (max-width: 1366px) 100vw, 1366px\" \/><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Cast gratings<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Cast gratings have a square or rectangular grid pattern. They are produced with a casting mold where bundles of fiberglass are laid in layers at a 90 degree angle. This provides a load-bearing capacity in both directions in the horizontal plane. Regardless of the way and manner in which the gratings are used, the strength will be distributed evenly across the grating.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1366\" height=\"1025\" src=\"https:\/\/glassfiber.no\/wp-content\/uploads\/9bc2cdf1-71ed-4570-aaa6-55da289945bd-1366x1025.png\" alt=\"\" class=\"wp-image-1579\" srcset=\"https:\/\/glassfiber.no\/wp-content\/uploads\/9bc2cdf1-71ed-4570-aaa6-55da289945bd-1366x1025.png 1366w, https:\/\/glassfiber.no\/wp-content\/uploads\/9bc2cdf1-71ed-4570-aaa6-55da289945bd-768x576.png 768w, https:\/\/glassfiber.no\/wp-content\/uploads\/9bc2cdf1-71ed-4570-aaa6-55da289945bd.png 1920w\" sizes=\"auto, (max-width: 1366px) 100vw, 1366px\" \/><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Profile-based gratings<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Profile-based gratings are assembled together from longitudinal I-profiles. The profiles are produced by pultrusion and assembled together with transverse profiles that lock the I-profiles in position. Unlike cast gratings, profile-based gratings have load-bearing capacity in only one direction.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Dimensions<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The thickness of the grating and what we call profile thickness have a great impact on the strength of the grating.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Thickness of grate<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">We have grates with thicknesses from 12mm all the way up to 51mm.<br>This undoubtedly has a high effect on the strength of the grating. The thickness you choose should be based on the load to be carried and the possible free span.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Profile thickness<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Another dimension of the grating that determines the structural strength of the grating is the profile thickness. By profile thickness we mean the thickness that makes up the pattern on the grating, whether it is cast or profile-based gratings.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Profile pattern and opening<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Our cast gratings are designed with what we refer to as a profile pattern. This pattern is available in a number of different dimensions, and the combination of these dimensions and the profile thickness has a major impact on the strength and load-bearing capacity of the grating.<br><br>When we talk about openings, we are talking about our profile-based gratings. Opening refers to the distance between the I-shaped profiles in the grating, which is a key aspect of our profile-based gratings.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1366\" height=\"912\" src=\"https:\/\/glassfiber.no\/wp-content\/uploads\/family-photo-1366x912.webp\" alt=\"\" class=\"wp-image-915\" srcset=\"https:\/\/glassfiber.no\/wp-content\/uploads\/family-photo-1366x912.webp 1366w, https:\/\/glassfiber.no\/wp-content\/uploads\/family-photo-768x513.webp 768w, https:\/\/glassfiber.no\/wp-content\/uploads\/family-photo.webp 1500w\" sizes=\"auto, (max-width: 1366px) 100vw, 1366px\" \/><figcaption class=\"wp-element-caption\"><em>The difference in profile thickness.<\/em><\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1366\" height=\"911\" src=\"https:\/\/glassfiber.no\/wp-content\/uploads\/DSC05218-copy-scaled-1-1366x911.webp\" alt=\"\" class=\"wp-image-2029\" srcset=\"https:\/\/glassfiber.no\/wp-content\/uploads\/DSC05218-copy-scaled-1-1366x911.webp 1366w, https:\/\/glassfiber.no\/wp-content\/uploads\/DSC05218-copy-scaled-1-768x512.webp 768w\" sizes=\"auto, (max-width: 1366px) 100vw, 1366px\" \/><figcaption class=\"wp-element-caption\"><em>Some of our grates have a different surface pattern than the main pattern.<\/em><\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Load<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">On the product pages for the gratings you will find a load table that shows the load the grating is designed for. This is a good tool if you are unsure.<br>on whether the given grating is strong enough for your needs.<br>Here is an example of a load calculation on one of our 38mm gratings:<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1198\" height=\"475\" src=\"https:\/\/glassfiber.no\/wp-content\/uploads\/ca2c8a19-5554-4ea9-8188-38284198c78d-1.png\" alt=\"\" class=\"wp-image-2033\" srcset=\"https:\/\/glassfiber.no\/wp-content\/uploads\/ca2c8a19-5554-4ea9-8188-38284198c78d-1.png 1198w, https:\/\/glassfiber.no\/wp-content\/uploads\/ca2c8a19-5554-4ea9-8188-38284198c78d-1-768x305.png 768w\" sizes=\"auto, (max-width: 1198px) 100vw, 1198px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">It may look a little complicated, but we&#039;ll do our best to explain.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Open span<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">On the left side of the table you will see a list of open spans, i.e. the opening between underlying beams or supporting structure.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Load<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The white numbers in the yellow field at the top are the load given in kN (kiloNewton). 1kN = 100kg.<br>When we say load, we are talking about the weight that the grating must withstand.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On the left side of the table we refer to two different types of load, \u0394U and \u0394C.<br>\u0394U is the load evenly distributed per square meter, and \u0394C is the concentrated load per meter or line load on 1 meter. This says something about how the load is applied to the grating. \u0394 stands for Delta and in physics means change. In this case, the change the grating makes when a load is applied.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Bending<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The numbers in the middle of the table are how much the grating bends in mm. Take for example an open span of 800mm. Here we see that if we subject it to 8kN, it will bend 4.5mm with a uniformly distributed load (\u0394U) and 8.8mm with a concentrated load per meter (\u0394C).<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Max and recommended load<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">On the far right of the table you can see the maximum recommended load and the breaking load. By recommended load we mean the load that Glassfiber Produkter AS, together with advice from the manufacturer, recommends. Breaking load is the load that the grating can withstand before it breaks in two.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Binder<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">As we have<a href=\"https:\/\/glassfiber.no\/en\/professional-articles\/glassfiber-fremtidens-produkter\/\">&nbsp;explained in this article about what fiberglass is and what it is made of<\/a>, binder is one of the components of fiberglass.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We have gratings that consist of one of four different binders. All binders provide high strength, long life, and fire retardant properties; but some binders can also provide additional properties.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Orthopolyester<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Orthopolyester offers a good balance between performance and cost, with sufficient chemical resistance for a variety of applications and good mechanical strength. This type is well suited for water treatment, architectural applications, and general industrial use.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Isopolyester<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Isopolyester offers good chemical resistance and weathering durability, making it a good choice for both outdoor and industrial applications where moderate exposure to chemicals occurs. Gratings using Isopolyester are cost-effective and offer solid strength.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Vinyl ester<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The vinyl ester binder is distinguished by its superior chemical resistance, especially against acids and strong alkaline chemicals. Vinyl ester is ideal for use in extremely corrosive environments found in the chemical industry. The gratings also have excellent mechanical properties and durability.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Phenol<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Phenolic gratings are known for their exceptional fire resistance and low smoke emission, making them a preferred choice for fire-prone areas such as offshore and tunnels. They have good chemical resistance and contribute to increased safety.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"980\" height=\"980\" src=\"https:\/\/glassfiber.no\/wp-content\/uploads\/samling-rist-980x980-1.webp\" alt=\"\" class=\"wp-image-2032\" srcset=\"https:\/\/glassfiber.no\/wp-content\/uploads\/samling-rist-980x980-1.webp 980w, https:\/\/glassfiber.no\/wp-content\/uploads\/samling-rist-980x980-1-150x150.webp 150w, https:\/\/glassfiber.no\/wp-content\/uploads\/samling-rist-980x980-1-768x768.webp 768w\" sizes=\"auto, (max-width: 980px) 100vw, 980px\" \/><figcaption class=\"wp-element-caption\"><em>Gratings with different types of binder, most often indicated by the color of the grating.<\/em><\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Surface<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The surface of the gratings can also be available in different variants that are suitable for different uses.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Non-slip surface with finely divided sand<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A surface with finely divided sand provides the highest friction and is our most slip-resistant surface. This is our standard surface and a good choice if you want high safety against slipping over a long period of time. Well suited for applications where deposits or fouling can occur.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Arc-shaped\/concave surface<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">An arched surface occurs naturally during the casting process. This provides good slip resistance and, compared to a sand surface, is easier to keep clean.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Grating with plate<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Our gratings are available with a typical 3 mm plate covering the grid pattern. The grating then has a tight surface that can be used where, for example, water or other things need to be prevented from falling through the grating. The plate surface is supplied with finely divided sand as an anti-slip or with a teardrop plate pattern.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Smooth surface<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Our final option is a smooth surface on both sides of the grating. This is only available for our 12mm thick gratings. Typically used for protection against moving machinery or rotating equipment.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1366\" height=\"1025\"

to the production method described earlier in the article. This category of gratings is our most versatile grating and is suitable for most applications. The gratings are available in thicknesses from 12mm all the way up to 51mm, and a profile thickness of 12mm.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Profile-based gratings<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">This type of grating often has a higher strength and is best suited for large open spans or other situations that require a higher degree of strength compared to cast gratings. This is due to the longitudinal I-profiles that provide high strength in one direction.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Heavy-duty gratings<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">If you need the toughest type of grating, then you are looking for heavy-duty gratings. These are available in both cast 51mm thick and profile-based 64mm thick. The profile-based version stands out with its profile pattern, which provides extra strength.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Stair steps<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Cast and profile-based stair treads are, as the name suggests, suitable for use as stair treads. The reason is their reinforced edge at the front, which is usually marked in yellow as a signal color. This is done to strengthen the points on the grate that experience the most stress, i.e. at the front.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-text-color has-luminous-vivid-amber-color has-alpha-channel-opacity has-luminous-vivid-amber-background-color has-background\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Summary<\/strong><\/h3>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\">Throughout this article, we have explored gratings \u2013 from basic explanations and applications, to the different manufacturing methods and components used. We have seen how dimensions and profile selection play a critical role in determining the strength of the grating and its suitability for specific applications. We hope you are now better equipped to consider which type of grating best meets your specific needs, whether for industrial walkways, platforms, stair treads, or other applications.

Dette f\u00f8rer til dannelsen av oksider eller andre forbindelser \u2013 en prosess vi kjenner som korrosjon. Oksygen er alltid til stede i omgivelsene v\u00e5re, noe som gj\u00f8r at korrosjonsprosessen i praksis alltid p\u00e5g\u00e5r, selv om den ofte skjer sv\u00e6rt langsomt.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Den naturlige reaksjonen mellom metall og oksygen er som regel ikke et stort problem i seg selv. Det finnes imidlertid flere faktorer som kan akselerere korrosjonen betydelig. Vann spiller en sentral rolle ved \u00e5 omdanne reaksjonen til en raskere elektrokjemisk prosess. Vannets sammensetning har ogs\u00e5 betydning \u2013 enten det dreier seg om fuktighet i luften, sj\u00f8vann eller vann som inneholder oppl\u00f8ste salter eller syrer.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"980\" height=\"653\" src=\"https:\/\/glassfiber.no\/wp-content\/uploads\/rustet-bolt-container-980x653-1.webp\" alt=\"\" class=\"wp-image-2016\" srcset=\"https:\/\/glassfiber.no\/wp-content\/uploads\/rustet-bolt-container-980x653-1.webp 980w, https:\/\/glassfiber.no\/wp-content\/uploads\/rustet-bolt-container-980x653-1-768x512.webp 768w\" sizes=\"auto, (max-width: 980px) 100vw, 980px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Hva milj\u00f8et betyr for korrosjon<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Milj\u00f8faktorer spiller en avgj\u00f8rende rolle i \u00e5 bestemme korrosjonshastigheten.

For the upstand towards the wall and the skirting board at the railing, an angle profile in fiberglass is used, which is bolted down to the grating deck. Transitions are sealed with elastic sealant. An alternative is to use an F-profile (article no. 11431) in fiberglass around the grating deck.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div style=\"height:61px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-text-color has-luminous-vivid-amber-color has-alpha-channel-opacity has-luminous-vivid-amber-background-color has-background\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Adaptation to arches and irregular geometries<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In projects with curved platforms or round pools \/ tubs, the grating deck is cut to meet the curvature. To follow the curvature, a 3 mm fiberglass plate with a typical height of 140 mm is used, which is mounted to the cut surface of the grating deck and grouted tightly. The plate is supported at the bottom of the remaining deck with corresponding 3 mm fiberglass plate pre-adjusted in arc segments using CNC machining.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Drainage and penetrations<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Grate covers can be installed with a slope for drainage. Standard plastic drainage pots can be installed on the underside to collect spills and washing water.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pipe penetrations or other technical penetrations in the grating are drilled or cut and grouted with elastic grout. Fiberglass is easy to process at the installation site with hand tools such as a circular saw, angle grinder, jigsaw or hole saw.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Applications in practice<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Fiberglass grating covers are used where equipment and instruments located on the underside of a platform or mezzanine need to be protected from possible spills from the overhead deck. This can be liquids from operating operations, leaks or water from cleaning processes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Typical applications are in water treatment plants, fish farming, the process industry and areas where there are requirements for washable surfaces and controlled collection of liquids.<\/p>\n\n\n\n<div style=\"height:58px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-text-color has-luminous-vivid-amber-color has-alpha-channel-opacity has-luminous-vivid-amber-background-color has-background\"\/>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"616\" height=\"462\" src=\"https:\/\/glassfiber.no\/wp-content\/uploads\/Skjermbilde-2025-11-28-104516-1-edited.webp\" alt=\"\" class=\"wp-image-2047\"\/><\/figure>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"357\" height=\"309\" src=\"https:\/\/glassfiber.no\/wp-content\/uploads\/Skjermbilde-2025-11-28-133150.webp\" alt=\"\" class=\"wp-image-2040\"\/><\/figure>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"544\" height=\"408\" src=\"https:\/\/glassfiber.no\/wp-content\/uploads\/Skjermbilde-2025-11-28-133240-1-edited.webp\" alt=\"\" class=\"wp-image-2046\"\/><\/figure>\n<\/div><\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Installation conditions<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The installation itself is relatively simple, and fiberglass can be cut and drilled with ordinary tools without heat or sparks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Closed grating decks take slightly longer to install than open gratings due to jointing and adjustment of sheets and profiles.
