Everything You Need to Know about Steel Grating

Jan. 12, 2022

Steel grating is also known as grating, steel grating, and grid. The steel grating is made of flat steel in a cross-arranged arrangement according to the specified spacing and cross-bars (twisted square steel, square steel, round steel, flat steel, etc.) . And welded into a steel product with a square lattice in the middle. The steel grating is mainly used for drain cover, steel structure platform board, steel ladder step board and so on. The crossbar is generally twisted square steel. The steel grating is generally made of carbon steel, and the surface is hot-dip galvanized to prevent oxidation. It can also be made of stainless steel. The steel grating has the properties of ventilation, lighting, heat dissipation, friction and explosion-proof.


Steel Grating


Production method of steel grating: Pressure-welded steel grating is made of loaded flat steel and crossbars arranged at a certain distance between the latitudes and longitudes. It is welded into the original plate by 200 tons of hydraulic resistance welding automation equipment, and processed by cutting, perforating, hemming and other processes. Become the product requested by the customer. Loaded flat steel spacing: the center distance of two adjacent loaded flat steels, commonly used are 30MM and 40MM. Crossbar spacing: The center spacing of two adjacent crossbars is usually 50MM, 100, two types, which can be produced according to customer requirements. Compared with checkered steel plates and other gratings, steel gratings have the following advantages: saving materials: the most economical way to withstand the same load conditions, and correspondingly, it can reduce the material of the supporting structure. Reduce investment: save materials, save labor, save construction period, and avoid cleaning and maintenance. Simple construction: Fix it with bolt clamps or welding on the pre-installed support, which can be completed by one person. Time saving: the product does not need to be reprocessed on site, and the installation is very fast. Durable and practical: Hot-dip galvanized anti-corrosion treatment before leaving the factory, with strong impact and heavy pressure resistance. Modern style: beautiful appearance, standard design, ventilated and light, giving people an overall smooth modern feeling. Light structure: less materials, light structure, and easy to hoist. Prevent accumulation of dirt: no accumulation of rain, ice, snow and dust. Reduce wind resistance: due to good ventilation, wind resistance is small in case of strong wind, reducing wind damage. Simple design: no need for small beams, simple structure, simplified design; no need to design detailed drawings of steel gratings, just indicate the model number, and the factory can design the layout drawing on behalf of the customer. Ventilation, lighting, heat dissipation, explosion-proof, friction: acid and 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.
