FAQs About GRP Grating
What is GRP grating used for?
GRP grating is commonly used for industrial walkways, platforms, riser floors, trench covers, and access structures in areas that require slip resistance, corrosion resistance, and non-conductive properties.
What are the advantages of GRP grating over steel?
Unlike steel, GRP grating does not rust, is lightweight, non-conductive, and requires no painting or coating. It is also easier to install and maintain, especially in harsh environments.
Is GRP grating slip-resistant?
Yes. Our grating features an integrated quartz-gritted surface that exceeds BS 7976 slip resistance standards, making it ideal for wet, oily, or high-traffic areas.
Can GRP grating be used outdoors?
Absolutely. GRP is UV-stable and weatherproof, which makes it perfect for coastal, marine, or outdoor industrial environments.
What sizes are available for GRP grating panels?
Panels are typically available up to 1220 mm x 3660 mm, with thickness options of 25 mm and 38 mm. Custom sizes can be manufactured to suit specific project needs.
Is GRP grating compliant with UK and European standards?
Yes. It complies with BS 4592, BS EN ISO 14122, EN 13501-1, ASTM E84, and BS 7976 for structural safety, fire performance, and slip resistance.
How long does GRP grating last?
With proper installation, GRP grating typically lasts 25 years or more. It requires very little maintenance and performs well in tough industrial conditions.
