Manufactured from ASTM A-1011 mild carbon steel, steel grating has been the most popular grating system for most applications including industrial and commercial flooring, buildings, walkways, platforms, safety barriers, drainage covers and ventilation grates. Steel bar grating is available in four fabrication methods - welded, riveted, swage locked and dovetail pressure locked. Each fabrication has its own character.
Steel gratings are often applied by external coating to extend its service life. Hot-dip galvanization and PVC coating protects interior steel from erosion of rains, snows and other elements.
