Custom Built Tanks
Over the past decade, TEK-TANKS designers and engineers have developed a tank construction system using high strength, advanced polyethylene materials that overcome the persistent corrosion and weight problems of stainless steel and the mechanical failure of flexible bag style tanks. Over 40% of our current work is building replacement tanks for boats previously fitted with mechanically unreliable flexible bags or stainless and aluminium tanks with electrolysis problems.
