Category: Pressed Steel Sectional Panel Water Tank

Pressed Steel Sectional Tanks are the industry standard for high-volume, modular liquid storage. Unlike one-piece tanks, these are constructed from individual, hydraulically pressed steel panels that are bolted together on-site. This “Lego-like” assembly makes them the ideal solution for locations where access is restricted or where massive storage capacity is required.

A prime example of this technology in action is Rainbow Tanks. As a leader in the industry, Rainbow Tanks utilizes high-strength Aluzinc or galvanized steel panels to provide premium, long-term storage solutions that are specifically engineered to withstand harsh environments and high-pressure demands.
