ROTH double-wall tanks are designed to offer the highest level of environmental protection. Every inner ROTH tank is made of blow molded, high-density polyethylene that is seamless and absolutely leak-proof and corrosion-resistant. In addition, ROTH tanks feature top connections to ensure the oil stays where it should.

The outer tank is made of leak-proof corrosion resistant steel which is capable of containing at least 110% of the capacity of the inner tank for maximum protection. The outer tank is made of galvanized steel, roll seamed (no welds) with an oil and fire resistant seal, making it one of the safest and most reliable tanks on the market.
