Product Description

Product Description

Hot Dip Galvanized Mill Finish Plain or Serrated Steel Walking Bar Grating with CE Approval For Industry Flooring and Mezzanine Graing

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.

Product Parameters

Bar grating types are specified by bearing bar spacing followed by cross rod spacing.
