Welded Steel Bar Grating is made by Carbon or mild steel of certain sizes through the processing of grooving, lock-pressure, welding, finishing and other treatment. While available in materials like copper and aluminum, steel grating is most commonly used due to its economic cost and excellent properties.
With robust design and spanning abilities, welded steel bar grating provides strong and safe support for floors and elevated walkways. Common applications include:
