Rainwater grates are made of flat steel and twisted square steel, or flat steel and flat steel welded together. Rainwater grates have the advantages of beautiful appearance, 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 than cast iron water grates, but the disadvantage is that its strength is not as high as cast iron water grates.
size
(1) The direction of the flat steel is the load-bearing (supporting) direction, and the length L of the flat steel is determined by leaving a gap according to the width of the ditch (well).
(2) Arrange according to the groove length, take a standard board width of 995mm that fits the processing module, and leave a gap of 5mm between the boards.
(3) The remaining length of the ditch (well) lacks 1 meter of local model size.
(4) Select the steel grating plate model based on the width of the ditch (well) and the load-bearing requirements.
(5) We propose to stop design and construction by choosing standardized sizes. Our company can design and manufacture various sizes or have other functions according to user requests
