Heavy Duty Welded Steel Grating is a great selection when strength is required in architectural and industrial applications. This type of grating is produced when carbon steel or stainless steel perpendicular bars are welded at each connecting point.
Heavy Duty Welded Steel Grating ranges in size from 1-1/4" X 1/4" bearing bars through 6" x 1/2" (7" bearing bars available by inquiry). Standard bearing bar spacings are 15/16", 13/16", 1-3/8", 1-7/8" and 2-3/8" center-to-center. See pages 25 and 27 for standard cross bar design. Rectangular cross bars are also available. Standard cross bar spacings are 4" or 2" center-to-center.

Process: raw material preparation (flat steel, steel bar) - pressure welding - Twisted steel grinding cutting - edging - galvanizing - Inspection - Packaging - storage
           Feature           Â
1. High strength, light structure: solid grid pressure welding structure has advantages of high load, light structure, easy installation, etc.
2. Fine appearance, durable in use: hot zinc dipping surface treatment makes it own fairly good corrosion resistance, bright and beautiful surface.
3. Good ventilation, lighting, thermal, anti-explosion, and anti-skid performance.
4. Prevent dirt deposition.
