Product Description

Heavy Duty Galvanized Steel Grid Trench Drain Grating Cover for Construction

Pressure Welded bar grating is forge-welded, a system in which NJMM was a pioneer. 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 per pound than mechanical assembly methods.

The twisted cross rods provide a non-slip walking surface. For applications where extremely slippery conditions prevail, Serrated bar grating offers a superior grip surface to the load bearing bars.
