Full-Service Industrial Metal Processing, Code Welding, and Fleet Maintenance

Since 2013, BEP Petroleum & Tank has provided specialized cargo tank trailer repair, heavy metal fabrication, and professional welding services from our shop in Bismarck. We don't just pull parts off a shelf—we are a complete, in-house industrial solutions facility built to keep North Dakota's fleets moving and commercial operations running.

Our shop is uniquely split into two high-performance departments to serve your needs under one roof:

• Commercial Tank & Trailer Services: We are Bismarck’s premier facility for certified cargo tank maintenance, specialized fleet inspections, and certified National Board R-Stamp structural repairs. From routine DOT compliance testing to heavy structural modifications, we handle the demanding code work standard commercial garages cannot touch. We provide complete meter calibrations, programming, and repairs on fuel and LPG bobtail trucks—available both on-site at your facility or right here in our shop. We also handle the ongoing repair and maintenance of stationary bulk storage tanks to ensure absolute compliance and safety.

• In-House Metal Cutting & Fabrication: Powered by our CNC plasma cutting, precision waterjet processing, and heavy-duty press brake forming machinery, our fabrication department shapes raw metal to your exact blueprints or sketches. We specialize in everything from custom generator stands and fleet utility beds to contract production runs for regional suppliers.

By matching our proven machinery floor with our own on-site inventory of raw steel and aluminum, we eliminate third-party vendor delays. Your project moves instantly from material selection to the production line or repair bay, keeping your lead times short and your equipment operational.

Whether you need an emergency agricultural repair, on-site bobtail meter calibration, a high-volume manufacturing partner, or a complete fleet overhaul, BEP delivers field-ready results anywhere in North Dakota.
