Overview
Lipp tanks have been on the market for over 45 years with a unique design: built from the ground up on site using a patented double-fold system that interlocks coiled steel bands into a seamless, spiralling wall.
How a Lipp tank is built
A special profiling and folding machine draws steel strip from a coil, forms the edges and folds them into the band below. The wall rises as the machine rotates, producing an edge-less and smooth finish that guarantees maximum tightness and stability with no on-site welding and no bolted joints to leak.
Only one specialist and two competent assistants are needed to erect a tank, and a wide range of roof configurations, from open top to membrane gas roofs, can be fitted.
VERINOX duplex steel
Lipp developed VERINOX, a duplex material layer system that bonds a stainless steel interior to a galvanised steel back. The product side gets full corrosion resistance where it matters, while the hybrid construction offers substantial cost savings over solid stainless.
