KBK manufactures double wall underground fuel storage tanks certified to UL 1316 standards. Underwriters Laboratories 1316 established this standard to address safety issues regarding protection from leakage, buckling due to external pressure, and the ability of the tank to withstand internal pressures or vacuums that may develop in the tank. It also specifies the materials of construction, so they meet the compatibility requirements of the stored fluids and ground conditions.
Being UL listed is a special distinction, and it means a product will safely perform its job as intended. Products earn that certification by undergoing rigorous testing against standards developed by UL. To achieve Underwriters Laboratories Listing, KBK’s tank design, construction materials, and sample tanks have successfully passed this rigorous testing to ensure you get the highest-quality product possible.
