What are the specifications required for steel bollards used for vehicle protection for oil tanks?

The specifications for steel bollards used for vehicle protection around oil tanks are designed to ensure proper strength and spacing to prevent damage from vehicles. The choice of 4-inch diameter and 6-foot length reflects a balance between structural integrity and practical installation.

A diameter of 4 inches provides enough strength to withstand typical impacts while remaining manageable for installation. The length of 6 feet ensures that the bollard extends sufficiently above the ground to be visible and effective, and it also allows for adequate anchoring below the surface to enhance stability.

The maximum spacing of 3 feet between bollards is critical in offering effective protection. This spacing helps prevent a vehicle from easily passing between bollards, thereby maintaining the intended barrier around the oil tanks.

Overall, these specifications meet safety standards by ensuring that the bollards can absorb the impact from vehicles, effectively acting as a protective barrier while not being overly cumbersome or difficult to install.
