Installation of serrated bar 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.
