4" Bolt-Down / Surface-Mount Stainless Steel Safety Bollard – Durable, Adaptable, and Professional
Our 4" bolt-down stainless steel safety bollards offer heavy-duty protection with a sleek, professional design—ideal for parking lots, storefronts, loading docks, schools, warehouses, government buildings, and commercial or municipal facilities. Engineered for secure surface-mounted installation, these bollards can be anchored directly to concrete or asphalt without excavation, making them one of the fastest and most flexible solutions for traffic control, pedestrian guidance, and asset protection.
Built from 304 stainless steel (316 available upon request), each 4" bollard delivers outstanding corrosion resistance and impact durability, even in harsh outdoor environments. The larger 4-inch diameter provides increased visibility and presence, making it ideal for both protective and architectural applications.
Our surface-mount design is perfect for locations that require clear vehicle and pedestrian delineation without disturbing existing pavement. This flexibility also allows for easy relocation or repositioning if site layouts change in the future.
