This 6-pack 42-inch steel safety bollard set provides strong protection for traffic control, parking areas, warehouses, and pedestrian safety zones. Each post is made from heavy-duty Q235 steel with a powder-coated yellow finish for rust resistance, Uv protection, and long-term outdoor durability. The 4.5-inch diameter pipe is paired with a reinforced 7.9 x 7.9-inch welded base for improved stability and impact resistance. Designed for high-visibility safety, the bright yellow color enhances awareness in day and night conditions. The set includes 24 heavy-duty anchor bolts for secure installation without welding. Ideal for preventing vehicle intrusion, defining restricted areas, and improving site safety in commercial and industrial environments.
