steel gratinginrtroduction

guttage steel grating is made of general carbon bearing bars, stainless steel ,brass sheets,aluminum sheetsof certain size by such operation slotting(trepanning)----spicing----welding finishing, with features of being light weight, high strength, anti-corrosin,free maintance and attractive in appearance, they are widely applied incivil engineering areas like civilian and commercial constructions, theaters,subways,and city constructions.

They can be used in suspended ceilings,interior and exterior decoration and renovation ,platform walkway,airvent window,billboard,andcover board

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.
