LFM’s fiberglass tanks present an outstanding value when compared to steel tanks.  Our tanks have a longer service life than tanks fabricated from other materials, which translates into replacement cost savings.  Additionally, our high-quality, one-piece tanks weigh approximately 60% less than steel tanks, making installation and site transfer easier and less expensive.

Grounding Solutions and Lightning Protection

LFM understands that static discharge is a tank issue, not a fiberglass issue. All tanks in the oilfield – steel, internally coated steel, and fiberglass – are subject to static current imbalance without proper grounding. As such, any tank of any composition can be struck by lightning without proper lightning protection to overcome static electricity. We offer simple grounding solutions for all of our oilfield tanks. And remember, even when including the nominal cost for proper grounding and lightning protection, fiberglass tanks cost 10 to 20 percent less than other options.

Strong & Lasting Construction

Our fiberglass gun barrel tanks are engineered for the specific service conditions required by our customers. LFM builds fiberglass tanks to provide a long and trouble-free service life. We maintain individual inspection reports for each tank, recording such information as resin system used, actual material usage, fittings, accessories, and delivery destination. The inspection reports are filed for future reference and copies are available upon request. Our excellent inspection program assures that each of our customers receives the highest quality fiberglass products available.

Professional Delivery

LFM has its own fleet of delivery trucks specifically equipped to transport fiberglass tanks.  We employ a professional delivery staff whose primary goal is to provide safe and courteous on-time delivery of our tanks to our valued customers.

Quality Assurance

At LFM, we stand behind the products we build.  We offer a one-year warranty for workmanship and a lifetime warranty against rust and corrosion on our fiberglass gun barrel tanks.  Speak to your LFM sales representative for complete details.
