This hot-dip galvanized municipal road steel grating cover is designed to address common pain points of traditional drainage covers including poor corrosion resistance, weak anti-slip performance and insufficient load-bearing capacity. Made of high-quality Q235 low-carbon steel and treated with hot-dip galvanizing, it forms a dense protective zinc layer that resists rainwater erosion, ultraviolet radiation and long-term outdoor exposure, offering a 15-year maintenance-free service life. With a C250 load rating meeting the traffic requirements of municipal sidewalks and light-duty vehicle passages, its 30x100mm grid size ensures efficient rainwater drainage while preventing debris from clogging the drainage system. It is widely applied in urban road drainage, community sidewalk covers and park landscape drainage projects, providing a safe, durable and eco-friendly drainage solution for municipal construction.
