Heavy Duty Welded Bar Grating is designed for industrial rolling loads. It is sturdy and can carry heavy loads and maintain high levels of use over many years. Heavy Duty Grating is resistance welded for durability, strength, and safety. Standard widths are 2′, 3′, and 4′ in 20′ lengths. Standard bearing bars are 1/4″, 5/16″, and 3/8″ thick. Bars range from 1″ through 8″ deep allowing AMICO to fabricate unique shapes and sizes for trench drains to large expanses requiring grating to support the heaviest rolling equipment.
