Galvanized steel grating manufacturer

The steel grating is a kind of steel product which is made of flat steel and cross bars (twisted square steel, square steel, round steel, flat steel, etc.) according to a certain spacing, and welded into a square lattice in the middle. The steel grating is mainly used to make ditch cover plate, steel structure platform plate, steel ladder step plate, etc. The cross bar is generally made of twisted square steel. The 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, anti-skid and explosion-proof.

Production standards of steel grating: Chinese yb4001-1991 and Yb / t4001-1998 standards, and can also be produced according to British bs4592-1-1995 and American ANSI / NAAMM (mbg531-88) and other standards.

Manufacturing method of steel grating: the pressure welded steel grating is a product required by the customer, which is made of load flat steel and cross bar arranged at a certain distance longitude and latitude, welded into the original plate with 200 tons of hydraulic resistance welding automation equipment, and processed through cutting, drilling, edge wrapping and other processes.

Spacing of load-bearing flat steel: the center distance between two adjacent load-bearing flat steels is usually 30mm and 40mm.

Cross bar spacing: the center spacing between two adjacent cross bars is usually 50mm, 100, and can be produced according to customer requirements. Compared with checkered steel plate and other grids, steel grid has the following advantages:

Material saving: the method of material saving under the same load condition can reduce the material of supporting structure accordingly.

Reduce investment: save materials, labor, construction period and cleaning and maintenance.

Simple construction: fix the pre installed support with bolt clamp or welding, and one person can complete it.

Save time: the product does not need to be reprocessed on site, and the installation is very fast.

Durable: hot dip galvanized anti-corrosion treatment before delivery, strong impact resistance and heavy pressure resistance.

Modern style: the appearance is beautiful, the design is standard, the ventilation is transparent, and the overall smooth modern feeling is given.

Light structure: less materials, light structure and easy to lift.

Reduce wind resistance: due to good ventilation, the wind resistance is small in case of strong wind, so as to reduce wind damage.

Anti Dirt: no rain, snow and dust.

Good ventilation, lighting, heat dissipation, explosion-proof and anti-skid performance

Simple design: no small support beam, simple structure and simplified design.

Acid alkali corrosion ability: in the range of pH 6 to pH 12.5, a stable protective film is formed on the surface of the zinc layer, with good corrosion resistance.
