For applications exposed to chemical spills, severe weathering, or marine environments, Glass Reinforced Plastic (GRP) grating and stair treads offer an ideal alternative to structural steel. GRP features an integrated angular quartz grit top surface that delivers an exceptionally high anti-slip rating. Because it is completely non-corrosive, non-conductive, and chemically inert, it retains its structural integrity and slip resistance over long lifecycles without requiring maintenance or recoating.
