A grating is any regularly spaced collection of essentially identical, parallel, elongated elements. Gratings usually consist of a single set of elongated elements, but can consist of two sets. Steel bar grating is manufactured in a variety of methods. Welded bar grating consists of load bars electrically fuse welded to cross bars. Pressure locked bar grating, or swaged grating, is where steel rods are forced through and locked in load bars. Riveted bar grating is where the load bars are riveted to the cross bars.
