Heavy Duty Permanent Steel Grating For Construction Building

JH Steel Grating

Galvanizied serrated grating is carrying flat steel and bars according to certain spacing orthogonal combination,to be open-steel components fixed by welding or pressure lock. Crossbar general use through twisted square steel may also be round steel or flat steel.

Material is divided into carbon steel and stainless steel. Steel grating mainly used for steel structure platform plate, trench cover, ladders treads, ceiling and other buildings.

Features

1.Hot-dip galvanizing: Rust strong, maintenance-free and replacement. 
2.Best drainage: water leakage area of 83.3%, is more than double the cast iron. 
3.Save investment: long-span. Heavy load than cast iron and the lowest savings in the cost of replacing stolen, then crushed. 
4.High strength: strength and toughness is much higher than cast iron, can be used for port, airport and other large span and heavy load conditions. 
5.Size Multi: different specifications can meet the different environments, load. Span, size and shape required.

Application

Steel grating is use of steel grid plate design and is widely used in city roads, squares, gardens, piers, airports, car parks, roads, railways, industrial engineering, civil construction of various industries.
