Metal bar grating is a type of flooring or platform made by forming a grid of parallel bars, usually made from steel, aluminum, or stainless steel. These bars are spaced apart to create an open area, allowing light, air, and water to pass through while maintaining a high load-bearing capacity. The manufacturing processes for metal bar grating include forging, welding, and pressing, with various configurations available to meet specific requirements, such as serrated surfaces for enhanced traction.
