Modern Welding Company


Today, Modern Welding Company has 9 steel tank and vessel fabrication subsidiaries located throughout the United States, two facilities that fabricate structural steel and special custom fabrication products and 5 welding supply stores located in Kentucky and Indiana. The company is an industry leader by being the country’s largest supplier of Underwriters Laboratories listed, underground and aboveground steel storage tanks for flammable and combustible liquids. Chemical storage tanks, ASME pressure vessels and structural steel fabrication are additional products manufactured by the company.

FIREGAURD®

Fireguard® is a “Protected” Fire Rated Aboveground Storage Tank with projectile, impact resistant and stream hose test ratings. This is a steel double wall aboveground storage tank with interstitial monitoring capabilities and a 2-hour fire rating. It can be built in horizontal and vertical configurations. These tanks may also be built with or without multiple compartments for multiple fuel storage. Each tank contains 3 inches of light-weight insulation material which has 75% less weight than traditional concrete insulations. Fireguard tanks are built to Underwriters Laboratories, UL-142 and UL 2085 specifications. Fireguard tanks also meet the CARB, California Air Resource Board, testing requirements for air emissions. Fireguard tanks are built in accordance with the Steel Tank Institute’s F-941 standard.

Fireguard’s UL-2085 construction standard meets and exceeds all the requirements set forth by UL-2080 for Fire Resistant Tanks.

If your project is required to follow NFPA 30 or 30A guidelines…Check with your area “Authority Having Jurisdiction” related to maximum allowable tank capacity for the class fuel being stored and secondary containment requirements.
