Steel is high strength, light weight, strong stiffness, therefore it is widely employed for the construction of large-span and super-high, super-heavy buildings; it is the ideal elastomer with perfect material homogeneity and isotropy which is most consistent with the basic assumption of general engineering mechanics;

Material with perfect plasticity, toughness and large deformation can receive dynamic loads well; short construction period; it is widely used in Industrials, so it is available with high degree of mechanization of specialized production; due to its high precision, high efficiency, good airtight , it can be used to build tanks, tanks and transformers. The disadvantage is poor fire resistance and corrosion resistance.

Steel Gratings Types We Supply

GNEE Steel Grating Application

Steel grating are designed and manufactured for various industrial and civil constructions in city road, gardens, yard, airport, railway and industrial engineering.

• Hot dip galvanized steel grating is the best choice for steel platforms in airports. Grating with 30 × 3 mm thick load bearing bars with a pitch of 30 mm and traverse bars at 50 mm or 100 mm is the suitable one.
• Steel grating, with robust design and spanning abilities, is very strong and safe for the support of floors and elevated walkway. It can be used for ceiling, interior decoration, platform aisle, ventilation windows, (Wells), advertising plaque and other construction.
• Widely used in the petrochemical industry, power plants, waterworks, sewage treatment plants, municipal works, sanitation projects in areas such as platforms, corridors, bridge, ditch cover, covers, ladders, fences, rails, and so on.
