The core technical highlights include the hot-dip galvanized surface treatment which forms a dense protective layer to prevent rust and corrosion for more than 15 years, and the serrated surface design that enhances anti-slip performance to avoid slipping accidents caused by rain or oil stains. It supports custom sizes and installation methods to fit different trench specifications, and is compatible with heavy vehicle traffic up to 250kN per meter. Compared with traditional cast iron covers, it has lower theft risk due to its relatively light weight and no obvious recycling value for scrap steel.
The standard specifications include 1000×500mm, 1200×600mm and other customizable sizes, with plate thickness ranging from 30mm to 40mm and grating spacing of 30×50mm. The load rating covers Class C125 to C250 to meet the needs of different traffic scenarios. The areal weight is between 12kg and 18kg per square meter, and it meets the EN 124 European standard and ASTM A123 material standard, ensuring reliable quality and compliance with global construction regulations.
This product is suitable for main urban roads, heavy-duty parking lots, industrial logistics parks, port terminals and other scenarios with high traffic load requirements. It can be used for rainwater trenches, sewage trenches and underground utility trenches, providing safe and reliable ground protection for various engineering projects.
