This general purpose mesh is used for reinforcing flat concrete elements such as floor slabs and walls, being galvanised it is suitable for use where exposure to corrosive elements (salt water etc.) would normally cause rust and deterioration of the standard ute mesh. This reo mesh is manufactured from L grade ribbed wires (D500L) that are welded together with equal spacing in both directions to form square apertures. 4B2 Mesh® is the same high quality reo mesh but produced in a handy 2m x 4m sheet, perfect for smaller jobs like driveways or DIY.
