Frequently Asked Questions
FRP stands for Fiber Reinforced Polymer, while GRP stands for Glass Reinforced Plastic. In the context of industrial gratings, these terms are generally used interchangeably to describe composites reinforced with glass fibers.
Orthophthalic is suitable for general use; Isophthalic provides better corrosion resistance for chemical plants; Vinyl Ester is recommended for highly aggressive chemicals and extreme conditions.
Yes, we offer a "Grit Top" surface where quartz or aluminum oxide particles are embedded into the surface during manufacturing to provide a high-traction, non-slip finish.
Absolutely. By adjusting the bar thickness and the mesh spacing, we can engineer gratings to support specific load requirements, including heavy machinery and pedestrian traffic.
While not completely fireproof, our GRP gratings can be manufactured with fire-retardant additives to meet strict safety standards like ASTM E84, ensuring they are self-extinguishing.
Installation is much faster due to the material's light weight. It can be cut on-site using standard power tools and is typically secured with GRP or stainless steel clips.
