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=\"http:\/\/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=\"http:\/\/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=\"http:\/\/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. Once decks are completed, they require little follow-up beyond visual inspection of joints and fasteners.<\/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<p class=\"wp-block-paragraph\">Fiberglass mesh covers are a practical solution for facilities that require tightness, corrosion resistance and easy cleaning. They are flexible and can be used for both straight and curved structures. The solution is particularly suitable where low maintenance and a predictable lifespan are desired.<\/p>","protected":false},"featured_media":2045,"template":"","meta":{"_acf_changed":false},"categories":[],"class_list":["post-2039","fagartikler","type-fagartikler","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.7 -
