Durbar is the registered trade name for hot-rolled mild steel plate featuring a raised diamond pattern on one face, which provides a proven anti-slip surface. It is the UK’s most widely used anti-slip flooring material, found in industrial buildings, mezzanines, ramps, access platforms, fire escape landings, and stair treads. F.H.Brundle stocks Durbar in flat sheet form as well as pre-cut stair treads and landing plates.
