Column BUFFA™ barriers can be supplied in diameters as low as 400mm and are an ideal, cost effective method of protecting lighting columns, structural columns, racking supports or similar items. Posts are manufactured from high-grade spring steel and are heat treated for strength and flexibility. Column BUFFA™ barriers distribute the impact forces evenly onto the flexible posts reducing the pull-out forces on the anchor bolts. The absorption of energy during impact offers a reduced risk of damage to the barrier, vehicle and structure.
