drain cover mesh Introduction:
Steel grating is made of flat steel in a certain spacing and cross bars (twisted square steel, square steel, round steel, flat steel, etc.), and is welded into a square with a square in the middle. A kind of steel product of lattice, steel grating is mainly used for gutter cover, steel structure platform board, steel ladder step board, etc. The crossbar is generally twisted square steel. Steel grating is generally made of carbon steel, and the surface is hot-dip galvanized, which can prevent oxidation. It can also be made of stainless steel. The steel grating has the properties of ventilation, lighting, heat dissipation, non-slip and explosion-proof.

drain cover mesh Feature:
1. High strength, light structure: solid grid pressure welding structure has advantages of high load, light structure, easy installation, etc.
2. Fine appearance, durable in use: hot zinc dipping surface treatment makes it own fairly good corrosion resistance, bright and beautiful surface.
3. Good ventilation, lighting, thermal, anti-explosion, and anti-skid performance.
4. Prevent dirt deposition.
