Founded in 1954 as “Structural Fibers”, the company originally produced aircraft and defense components. That quickly changed when Structural developed a patented process that revolutionized the water treatment market by introducing small composite pressure vessels.
Structural quickly became the recognized world leader in pressure vessel technology, expanding its product line with larger tanks for industrial applications.
Acquired by Pentair in 1999, Structural products are currently produced in Herentals (BE).
A large and growing product line keeps us first on our customers’ lists for depth and breadth. Ranging from residential pressure vessels for water softening and filtration to composite vessels for industrial water applications, Structural offers more with many value-driven accessories designed to make installation and service easier.
We work closely with our customers to help them to specify the right vessel for their requirements. If a standard vessel won’t do, we’re happy to customize one. In fact, Structural is one of the few companies capable of rotomoulding very large vessels to exactly match all customer needs. Even the color of the tank can be customized.
Moreover, Structural super tanks range can be designed according to almost any specific requirements. For more information, please download the dedicated super tanks brochure.
Structural tanks are CE PED (Pressure Equipment Directive) certified, which is the basic requirement for the EU market. Our manufacturing experience allows us to select the best raw materials in order to be compliant to Regional Potable Water Directives. For all these reasons, Structural tanks are covered with a five year warranty.
