6. mesh bar grating design
Steel bar grating is the most popular product
®manufactured by ESSA .
Nearly all sizes in Standard Mesh like this are
readily available in our warehouses.
Simplicity in design is surpassed by its versatility
in usage.
From mezzanines, platforms, catwalks, and stairs
to fences, benches, racking shelves,
and ventilation covers. Steel Bar Grating is by
no means limited to the industrial
applications for which it was originally designed.
Available in natural steel, primed paint, or hot
dip galvanized.

Bar grating is forge-welded, a system in which in this
process the bearing bars and cross rods are permanently
forged together by heat and pressure into a single
unit construction, resulting in greater strength than
mechanical assembly methods.
The twisted cross rods provide a non-slip walking surface.
For applications where extremely slippery conditions
prevail, Serrated Tru-Weld offers a superior grip surface
to the load bearing bars.
