Customize Stainless Steel or Heavy Duty Steel Floor Trap Grating
Steel Grating is the workhorse of the industrial flooring market and has served industry for decades. Strong and durable with an exceptional strength-to-weight ratio, metal bar grating can be easily fabricated to nearly any configuration.The high percentage of open area makes bar grating practically maintenance-free and all products are fully recyclable.
Steel Grating is designed to hold heavy loads with minimal weight. The gratings are made of bearing bars and cross bars. The bearing bar is the main load carrying bar which runs the same direction as span. The cross bars are connectors made from a strip or rolled bars which extent across or through the bearing bars. Cross bars are welded, forged or mechanically locked.
