Specifications


Steel bar grating plate is generally made of carbon steel hot galvanizing, appearance can prevent oxidation. It also can be made of stainless steel. Steel bar grating panel has many advantages such as ventilation, lighting, ventilation, non-slip explosion-proof performance.

1.Steel Bar Grating,
also known as steel bar grating and steel grating panel or sheet 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 propertier. The hot dipped zinc coating gives the product excellent anti-corrosion.
2.Material: high quality low carbon steel
3.Types: serrated and plain
4.Finishes: electro galv, hot dipped galv, according to the difference surface treatment.
5.Application:

galvanized steel grating are widely used by various plants such as electric power,petroleum,chemical industry,metallurgy industry,machinery industry,shipbuilding, harbor,oceanographic engineering,building,paper mills,cement plant,medicine,spinning and weaving,foodstuff factory,transportation,municipal administration,parking lot,etc.
