Series 1: 30mm centresSuitable for heavy loading
Available in mild steel (forge welded or twistlock) and aluminium (twislock)
Series 2: 40mm centresSeries 2 grating is available in both forge bar and twistlock. The lightweight, economical design of the Series 2 grating makes it perfect for walkways, fixed platforms, stairways and ladders. Available in twistlock (mild steel and aluminium)
Series 3: 60mm centresSeries 3 grating is mainly used in the mining industry as it minimises the build-up of spillages on the flooring. The openings let small matter fall through while larger matter is caught on the grating. Series 3 is a very lightweight design and is not recommended for high-impact loads.
Load Bar Direction and spacing
It is important to check the direction of the load bars when ordering steel grating as the load bar must take the weight on top of the support to prevent collapse.
