Rainwater Grating System
Rainwater grating systems are composite drainage solutions designed to safely and efficiently discharge surface water in roads, sidewalks, parking areas, and infrastructure projects. With high load capacity, anti-slip surface design, and long service life, they provide reliable performance in high-traffic areas.
Manufactured by Sterplas, GRP (Glass Fiber Reinforced Polyester) rainwater grating systems offer superior resistance to corrosion compared to concrete and metal alternatives. Their lightweight, maintenance-free structure makes them an ideal choice for municipal infrastructure, industrial zones, and commercial projects.
