Floor gratings, also known as steel gratings or metal gratings, are metal formed grid patterns made to provide traction and allow for water drainage over an opening. Gratings are common in industrial and commercial facilities and are used in production plants and on sidewalks where liquid or debris may be present. Floor gratings are available in both mild steel or hot dipped galvanised with plain or serrated designs. Gratings are strong and lightweight, making them an ideal choice for projects ranging from trenches and stair treads to decking and steel flooring.

The frame type of steel grating floor is based on the customer’s construction requirements and takes into account the deck’s performance characteristics. When you selecting a geometric dimension, it is necessary to think about the maximum dimension of the floor: 2500 × 2200 mm (2500 mm is the maximum length of bearing bar, 2200 mm is the maximum length of crossing bar). The best dimension of steel grating is 1500 × 1000 mm.
