Buff Bauxite is a natural, very hard mineral used predominantly in road systems for its high-friction and anti-skid properties. The majority of public sector systems will specify that Calcined Bauxite is used in their road and pedestrian crossing installations.
Buff bauxite’s hardness is also beneficial in internal and external industrial flooring applications where a very hard and long-lasting mineral is required to give high-friction, anti-slip performance.
Buff bauxite is used extensively in warehouses, loading areas, high visibility pedestrian, and vehicular safety areas.
