Steel fiber manhole covers and rainwater grates are made of fiber concrete as the matrix. The excellent compressive strength, tensile strength, flexural strength, impact strength, toughness, impact toughness and other properties of steel fibers are added to concrete.

Application areas: This product is widely used in municipal engineering, construction engineering, public works, gardening and other places and areas that require ground and road drainage and water discharge.

It can replace cast iron rainwater grates and manhole covers, which can reduce the weight of components by nearly 30%, reduce the cost by about 50%, meet the requirements of automobile load use, and effectively solve the problem of loss. Its overall dimensions are: grates (length × width × thickness) 750 × 450 × 35mm, and manhole covers are Φ750mm and Φ650mm.
