Improve traffic control and property protection with this 42-inch safety bollard post, designed for parking lots, driveways, garages, construction sites, and road markings. This yellow steel traffic bollard features a 4.5-inch diameter pipe welded to    a 7.9" x 7.9" base plate—significantly larger than hollow designs for enhanced grounding area and superior stability. Made from Q235 steel, this parking pole offers excellent hardness, durability, and rust resistance for long-term outdoor use. The    yellow powder coat finish provides high visibility, increasing driver awareness and caution while protecting against oxidation, UV rays, and harsh weather conditions. Installation is straightforward with 4 pre-drilled mounting holes on the base plate;    the included 8 anchor bolts allow secure mounting in minutes—simply drill, tap in anchors, and tighten. This driveway barrier works effectively as a traffic safety barrier, pedestrian flow guide, enclosed area protector for sanitation or construction    zones, and visual warning for parking spaces. Ideal for commercial and residential applications. Package includes 1 steel bollard post and 8 anchor bolts.Key Parameters:        Height: 42 inches        Diameter: 4.5 inches        Base plate size: 7.9" x 7.9" (fully welded)        Material: Q235 steel (hard, durable, rust-resistant)        Finish: Yellow powder coat (UV and weather resistant)        Mounting holes: 4 pre-drilled on base plate        Included hardware: 8 anchor bolts        Installation: Drill and bolt-down        Applications: Parking spaces, driveways, garages, construction sites, road markings, traffic barriers
