Toothed steel grating is also called serrated steel grating, anti-skid steel grating, etc. It is made of flat steel with a zigzag shape on one side and twisted square steel. One side of the flat steel with zigzag is welded with twisted steel, which has a very strong anti-slip effect, especially when the slope is greater than 5° to 20°. It is very suitable for application in wet and smooth places, such as: chemical plants, offshore oil production platforms, sewage treatment plants, etc.
The toothed steel grating has the characteristics of light weight, strong bearing capacity, easy cleaning, ventilation, lighting, heat dissipation, explosion-proof, etc. It can be used in conjunction with frame hinges as a ditch cover, and has the characteristics of anti-theft and safety.
The tooth-shaped steel grating is treated with hot-dip galvanizing, which has the characteristics of long service life and not easy to rust.
Toothed steel grating can be made of Q235 low-carbon flat steel, stainless steel or brass flat steel, and can be cross-welded with twisted steel, or flat steel and flat steel.
