Rainwater gratesIt is made by welding flat steel and twisted square steel or flat steel and flat steel. Rainwater grates have the advantages of beautiful appearance, drainage, high strength, multiple specifications, and low cost, so steel grating rainwater grates are usually used. With the development of technology, a new type of composite water grate is formed by using resin or plastic reinforced steel bars and inorganic fillers,The advantage is that it has a lighter weight and lower cost compared to cast iron water grates, but the disadvantage is that its strength is not as high as cast iron water grates.
