Dual laminates are made up of two layers: a corrosion-resistant inner layer that protects against chemicals and a sturdy fiberglass outer layer for structural support. The thickness of the corrosion barrier typically ranges from 3mm to 6mm, depending on the specific needs of the application.

The choice of materials is based on the chemical compatibility required for the job. Popular options include CPVC, PVDF and PP reinforced laminates. For instance, a PVDF-reinforced tank is highly suitable for the storage of pure sulfuric acid due to its excellent chemical resistance.
