Trench Grating Covers
Steel Trench Grates Used as Draining Covers in Waste Water System
Steel grating can be made into trench covers for well cover plates and gully covers. We can customize other types according to customer demands and drawings. Our trench cover plate generally consists of the steel grating, the angle iron frame and the embedded part. Surface treatment: Hot dip galvanizing.
Trench grates are used as draining cover, gully cover and well cover is used in city public works.
Processing and Welding of Trench Grating Covers:
1.lt is to use of high frequency automatic welding machine to do welding on the hot dip galvanized gratings and covers (except end plate welding).
It is not allowed to create melting-corrosion on the based material.
2.Material: Q195 or Q235 low carbon steel
3.Surface Treatment: After grating is formed, the surface is by hot dip galvanization; the thickness of galvanization is 610 g/m2.
4.End Plate Welding: Two sides of gratings are welded on with H*6 mm flat steel.
Welding slag is required to be cleaned.
