Product Introduction
FRP grating is a high-performance structural panel made of fiberglass reinforced resin composite, widely used in industrial and civil engineering fields. FRP grating adopts molded or pultruded process, with uniform grid and stable mechanical performance, and can be customized in size, thickness, color and surface pattern according to project requirements. FRP grating has excellent corrosion resistance, nonconductivity, slip resistance and fire performance, and can be stably used in harsh environments such as acid and alkali corrosion, high humidity and electricity safety demand. It is fixed by special clips, easy to install and cut, and can meet diversified engineering needs such as platform pavement, trench cover and operation channel.

Product Advantages
Lower long-term ownership cost
The product eliminates annual anticorrosion painting and replacement of steel grating, and the 15–20 years service life reduces material renewal expense by more than 60% compared with metal products.
Reduced installation & labor cost
Its weight is only 1/4 of steel grating, no large lifting equipment is needed, and the installation labor and time cost is reduced by about 50%–70%.
Customized cost optimization
Support on-demand cutting and hole opening, minimize material loss, avoid waste caused by improper size matching.
Application Scenarios
1. Industrial platforms: Chemical, electric power, petroleum, metallurgical operation platforms, equipment walkways, stair treads.
2. Environmental engineering: Sewage treatment tank covers, drainage ditches, water plant inspection channels, corrosion-resistant filter screens.
3. Civil & commercial: Car wash room floor drains, tree gratings, parking lots, pedestrian passages, landscape platform pavements.
4. Special environments: Electro-insulation workshops, antistatic areas, marine ships, coastal corrosion-prone areas.
5. Construction engineering: Ventilation grilles, trench covers, light load platforms, safety nonslip passages.
FAQ
Q: How much can the product save cost compared with steel grating in chemical corrosion environment?
A: Taking a 100 m² chemical workshop platform as an example, steel grating needs anticorrosion treatment every 1–2 years with annual cost about 30–50 yuan/m², and needs replacement in 5–8 years. the product has no maintenance cost and service life up to 15 years, and the total cost within 15 years is reduced by about 50%–65%.
Q: Can FRP grating be cut and installed on site, and what is the loss control?
A: the product can be cut on site with ordinary tools, and the factory provides precutting service. The cutting tolerance is 5–10 mm, and the professional layout can control the material loss within 3%–5%, which is lower than the 8%–12% loss of metal grating onsite processing.
