Installation of steel grating
1.Welding & using saddle clips are two ways for installation of grating. The welding is suitable for those places where there is no need to move or dismental,for instance,the flooring around the machines. However,using saddle clips are featuring in easy installation & saving zinc layer.
2.Regarding welding installation, angle wolding would used at the first bearing bar of every corner,which the welding length is no less than 20mm,&the height is no less than 3mm.
3.Saddle clip composed of a top plate,a hold down & a M8 bolt, is suitable for all kinds of steel gratings installation.
4.Regarding saddle clip installation, at laest four sets of saddle clips would be used in one pc grating.It would be better using more in the staddle for those gratings with a bigger span.
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.
