Heavy Type Welded Bar Grate
Heavy-Duty Steel Gratings
uses thicker (1/4", 5/16", 3/8") and deeper bearing bars.
Heavy-Duty Welded Grating has the strength for heavy-duty load
areas such as airfields, highways, industrial plants, truck and bus
terminals, parking lots and railroad yards. Common uses are
flooring, driveways, subway and tunnel ventilation grilles, curb
inlet grates, ramps, docks, etc.
Welded Heavy Duty Gratings are designed to service applications subject to heavy rolling and
static loads such as highways, plant floors, loading docks, inlet
covers and airports. Since these conditions can range from
light-duty forklifts to heavy-duty truck or aircraft traffic, heavy
duty gratings are manufactured in a wide range of bar sizes and
It is a sturdy grating to carry loads and maintain the same level
over many years of use. Whenever rolling wheel loads are to be used
over the grating, we recommend that the grating be load banded to
add lateral strength. Serrations are available on bars up to 3/8"
thick to provide additional traction for rolling loads.
Standard heavy-duty bar grating is resistance-welded for durability, strength and safety using an
automated electric/hydraulic welding process. High temperatures,
combined with high pressure, fuse the bearing bars and cross bars
together to form a permanent joint.
Also, EON-HESLY is one of the few manufacturers that has the capability of
providing you with those "really big" grates. If your application
is not adequately addressed by these load conditions, please
contact our engineering department and we will gladly assist in the
selection of a heavy duty grating to satisfy your specific needs.

How to Install 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.
