With Chequer Plate and Hinge Hot Dipped Galvanized Steel Grating for House Drain

specification

Hot Dipped Galvanized Steel Grating is the product in accordance with customers requirements that is lined by load flat steel and horizontal rod alternately in a certain space, welded into primary plate in the high voltage resistance welding machine, then through the deep-processing of such working procedures as cutting, slitting, tapping, bordure, etc.

This kind of steel grates can be embeded into the cement, which can make it more steady. The most important is that, we add a small plate on the frame, then people can lock the steel grating by clips, this also prevent some naugty children open the grates and jump and play in the sewer. Meanwhile, the surface is hot dip galvanized, it can stop it from being rust.
