Types Of Carbon Steel Trench Cover

There are three types of carbon steel trench cover: GM, GU and GM.

 GT: Steel grating trench cover is suitable for road occasions other than highways, and the general traffic volume is not large. When used as a cross-section ditch cover, the risk of jumping up of the cover shall be taken into consideration. The bolt-fixed ditch cover shall be adopted. The anticorrosion of the steel grating shall be hot-dip galvanized.

 GM: GM-type well hole steel grating covers can be used for the cover plates of rainwater wells, sink wells, drainage wells, sewage wells and other water supply and drainage wells or pores and manholes of municipal facilities such as roads and parks. The GM type well hole steel grating cover can generally be designed to be flipped, and the opening and closing angle of the normal flip is 110 degrees. The steel grating cover with hinge pin not only prevents theft but also simplifies the construction procedure. In order to improve the impact resistance, the GM-type well bore steel grating cover is generally made of steel grating with a cross-bar spacing of 50mm.
