Fiberglass Storage Tanks from Integra Tanks are created using the latest in robotic controlled manufacturing equipment to embed glass fibers into a cured thermosetting resin.

Fiberglass begins as individual strings of glass drawn from a furnace of molten glass. Many fibers of glass are formed simultaneously and gathered into a “strand”. These strands are then joined to create a variety of fiberglass products. Fiberglass Storage Tanks from Integra Tanks are created using a combination of Boron-Free E-glass, Chop Glass, Unidirectional Winding Glass, and 24oz Woven Glass.

Integra Tanks sources raw materials from industry-leading resin manufacturers. These materials are then weighed against bench-marked standards to ensure an exact fit to specifications. Depending on the intended usage, Fiberglass Tanks from Integra Tanks can be constructed from a General Purpose Resin or High-Performance Resins to achieve greater chemical and heat resistance.
