The core competitive advantage of this product lies in its integrated one-piece molding process and serrated anti-slip surface design. Compared with traditional cast iron covers, it boasts lighter weight, which reduces transportation and installation costs significantly. The hot-dip galvanized surface treatment extends the service life by over 3 times compared to ordinary painted steel products, effectively preventing rust and corrosion. Its unique grid structure enables rapid discharge of rainwater and sewage, eliminating road surface ponding issues, while the closed edge design prevents pedestrians or vehicles from getting stuck. It fully complies with the EN 1433 European road furniture standard, ensuring strict quality and safety compliance for municipal projects.
This product has standard specifications of 6000mm in length, 1000mm in width and 4mm in plate thickness, with a grid aperture of 30x100mm, flat steel width of 30mm, bearing bar spacing of 100mm and cross bar spacing of 50mm. The weight per square meter is approximately 22kg, and the load capacity meets the C250 grade standard of 250kN/m2. The surface zinc layer thickness reaches no less than 85μm, meeting the strict corrosion resistance requirements for outdoor municipal engineering. It supports custom sizes and load ratings according to customer specific needs, adapting to various narrow or special-shaped construction scenarios.
This hot-dip galvanized steel grating cover is mainly applicable to municipal road drainage ditches, community sidewalk coverings, park landscape drainage projects, underground garage entrance drainage covers and other public ground protection scenarios. It is suitable for pedestrian passage and light-duty vehicle passing areas, effectively solving the problem of road water accumulation and providing a safe and reliable ground facility for municipal construction and community environment management. It can also be matched with dedicated mounting frames to enhance overall stability and safety, meeting the diversified needs of different urban construction projects.
