Steel Driveway Grates Grating - Industrial Walkways & Perforated Metal Platforms

What is Steel Grating?

Steel grating is manufactured by arranging bearing bars and cross bars in a flat-steel weft pattern. The components are welded together using high-pressure resistance welding, followed by cutting, incision, opening, and overlock processes to create finished products according to customer specifications.
