Popular HDG drain cover serrated steel graing

 

Introduction of galvanized serrated grating:

Galvanized steel bar grating is made by welding with flat steel and bars with certain distances. It goes through cutting, opening, edging and other processes. The products enjoy the feature of high strength, light structure, high bearing, convenience for loading and other properties. The hot dipped zinc coating gives the product excellent anti-corrosion.

Advantages of galvanized serrated grating:

Steel grating offers the following advantages compared with steel grid sheets:

Steel grating has light weight, good strength, large carrying capacity and can save materials and cost. It offers good ventilation of light and wind, a modern sense, aesthetic appearance and anti-skid safety. It is also easy to clean, easy to installation and durable for uses.
