Cast Iron Drain Grate

This product is made of QT500-7 ductile cast iron material and is precisely cast after being spheroidized and further spheroidized treatment. It features high strength, good toughness, impact resistance, wear resistance, and corrosion resistance, meeting the requirements of standard mechanical properties.
This product adopts an integrated/frame structure design. The water distribution holes on the rain grate are evenly and reasonably distributed, with a large water channel area, allowing for smooth drainage. It can quickly drain the water on the road surface. The surface is cast with anti-slip patterns, enhancing the safety of pedestrians and vehicles. The grate is closely fitted to the frame, providing functions of preventing displacement, noise reduction, and theft prevention, effectively avoiding problems such as rolling, jumping, theft, and loss.
The load-bearing grade of this product can meet different working conditions such as A15, C250, D400, E600, and F900. It is suitable for urban roads, sidewalks, squares, residential areas, parking lots, and municipal drainage systems. Installation is simple, the stability is good, and the service life is long. It is an ideal supporting facility for municipal rainwater drainage projects.
