Nucor Grating has developed an international reputation for quality bar grating products since the company was established in 1954. Special equipment and manufacturing techniques are employed to ensure that maximum strength and durability are built into every steel and aluminum grating bearing the Tru-weld and Fisholow names. Tru-weld steel gratings are forge welded, a system in which Nucor Grating was a pioneer. In this process, the bearing and cross bars are permanently forged together by heat and pressure into a single unit construction which results in greater strength per pound than mechanical assembly methods. Fisholow Galok aluminum gratings employ a unique interlocking system that joins the bearing and cross bars together in panels of exceptional rigidity and strength.
