galvanized steel grating/walkway grating/steel grate decking/metal drain grates/sheet metal grate/catwalk grating
Galvanized Steel Grating is main type welded , surface treatment is electro-galvanized or hot-dipped galvanized .
type: serrated type , I bar type .plain type .
Bearing bar - A flat bar withstanding the main load is in consistent with the span direction .
bearing bar pitch - the distance center to center of the two bearing bars.
Cross bar - the connecting bars , made from twisted bar ,round bar or flat bar, which extend across the bearing bars .
Cross bar pitch - the distance center to center of the two adjacent cross bars.
Length (span)- the maximum dimension of a grating panel ,measured parallel to the bearing bar ,and in the same direction as the baering bars .
Width - the maximum dimension of a grating panel ,perpandicular to the bearing bars .and in the same direction as the cross bars.

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.
Packaging & Shipping
Packed in bundle then fixed by steel belt onto metal pallets as the general export package and customers' requirement is accepted .
