The surface consists of finely divided silica sand in gray (RAL 7001), which provides good slip resistance even in wet or oily environments. Because the grating has isophthalic polyester as a raw material, it also achieves fire class 1 (ASTM E84-05) with a flame spread of less than 25. This makes it well suited for demanding industrial environments, such as oil and gas, fish farming and electric power.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since the grating is 25 mm high, it can also withstand higher loads than the thinner variants. Therefore, it is well suited for walkways, platforms and other areas where both strength and slip resistance are important. In addition, the grating has insulating electrical properties, and at the same time it can withstand temperatures from -20 to +80 \u00b0C.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We supply the grating in standard panel size 1219 x 3658 mm, but can also cut it to the desired size if you need it. Please contact us and we will help you choose the right type for your project.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Plate dimension<\/strong><\/td><td>1219 x 3658 mm<\/td><\/tr><tr><td><strong>Height<\/strong><\/td><td>25mm<\/td><\/tr><tr><td><strong>Pattern<\/strong><\/td><td>Square, 38 x 38 mm<\/td><\/tr><tr><td><strong>Profile thickness<\/strong><\/td><td>6.5\/5mm (top\/bottom)<\/td><\/tr><tr><td><strong>Opening<\/strong><\/td><td>32 x 32 mm<\/td><\/tr><tr><td><strong>Open area<\/strong><\/td><td>68%<\/td><\/tr><tr><td><strong>Weight<\/strong><\/td><td>12.2 kg\/m2<\/td><\/tr><tr><td><strong>Weight per plate<\/strong><\/td><td>54.4 kg<\/td><\/tr><tr><td><strong>Surface<\/strong><\/td><td>Finely divided silica sand<\/td><\/tr><tr><td><strong>Color<\/strong><\/td><td>Grey (RAL 7001)<\/td><\/tr><tr><td><strong>Plastic raw material<\/strong><\/td><td>Isophthalic polyester<\/td><\/tr><tr><td><strong>Fire resistance<\/strong><\/td><td>ASTM E84-05, Class 1<\/td><\/tr><tr><td><strong>Flame spread<\/strong><\/td><td>&lt; 25<\/td><\/tr><tr><td><strong>Temperature range<\/strong><\/td><td>-20\u00b0C\/80\u00b0C<\/td><\/tr><tr><td><strong>Electrical conductivity<\/strong><\/td><td>Insulating<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;6a8d2c111de02&quot;}\" data-wp-interactive=\"core\/image\" data-wp-key=\"6a8d2c111de02\" class=\"wp-block-image size-large wp-lightbox-container\"><img loading=\"lazy\" decoding=\"async\" width=\"1366\" height=\"301\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on--pointerdown=\"actions.preloadImage\" data-wp-on--pointerenter=\"actions.preloadImageWithDelay\" data-wp-on--pointerleave=\"actions.cancelPreload\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/glassfiber.no\/wp-content\/uploads\/15020-15021-15022-15023-1366x301.jpg\" alt=\"\" class=\"wp-image-3433\" srcset=\"https:\/\/glassfiber.no\/wp-content\/uploads\/15020-15021-15022-15023-1366x301.jpg 1366w, https:\/\/glassfiber.no\/wp-content\/uploads\/15020-15021-15022-15023-768x169.jpg 768w, https:\/\/glassfiber.no\/wp-content\/uploads\/15020-15021-15022-15023-18x4.jpg 18w, https:\/\/glassfiber.no\/wp-content\/uploads\/15020-15021-15022-15023.jpg 1876w\" sizes=\"auto, (max-width: 1366px) 100vw, 1366px\" \/><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\tdata-wp-bind--aria-label=\"state.thisImage.triggerButtonAriaLabel\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"state.thisImage.buttonRight\"\n\t\t\tdata-wp-style--top=\"state.thisImage.buttonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewbox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><figcaption class=\"wp-element-caption\">Deflection in mm as a function of load in kg and open span in mm<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1366\" height=\"633\" src=\"http:\/\/glassfiber.no\/wp-content\/uploads\/4192446b-7e50-4eb0-b9b7-0bd82753489c-1366x633.png\" alt=\"\" class=\"wp-image-3064\" style=\"aspect-ratio:2.157996146435453;width:553px;height:auto\" srcset=\"https:\/\/glassfiber.no\/wp-content\/uploads\/4192446b-7e50-4eb0-b9b7-0bd82753489c-1366x633.png 1366w, https:\/\/glassfiber.no\/wp-content\/uploads\/4192446b-7e50-4eb0-b9b7-0bd82753489c-768x356.png 768w, https:\/\/glassfiber.no\/wp-content\/uploads\/4192446b-7e50-4eb0-b9b7-0bd82753489c.png 1842w\" sizes=\"auto, (max-width: 1366px) 100vw, 1366px\" \/><\/figure>","protected":false},"featured_media":1505,"menu_order":0,"template":"","meta":{"_acf_changed":false,"footnotes":""},"categories":[29],"class_list":["post-1504","produkt","type-produkt","status-publish","has-post-thumbnail","hentry","category-stopte-gitterrister"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.2 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Gitterrrist Artikkel nr. 15020 - Glassfiber Produkter<\/title>\n<meta name=\"description\" content=\"Gitterrist artikkel 15020, 25 mm tykkelse, 38x38 mm m\u00f8nster og sandet overflate.
