Profile: American Tanks specializes in providing tank storage units. We manufacture ship tank and liner products & transport and install custom modular design tanks. Our GRP, stainless steel, GFTS, and HDG panel tanks. Glass fused to steel panel tanks have been considered an essential tank option for applications including digester tanks, fire protection services, and wastewater treatment. Pit liners are used in ponds, dams, or other large in-ground basins to contain liquids safely and effectively. Energy sectors also utilize ponds or pits to store oil and gas and usually hold significant quantities of these substances. The concept behind industrial pit storage is to isolate harmful chemicals from the environment and minimize human exposure and health risks.
