We manufacture various types of GRP pipes and fittings for a wide range of applications.

Our production process is based on some sequential technical procedures that aim to guarantee top-quality products: for example, the outermost linear construction (internal chemical barriers) and the structural reinforcement of the weld (to guarantee the tightness required by the design data).

Pipe types

In Vetres, we manufacture pipes with continuous support (namely, buried along their entire length) and pipes on X-span supports (which means, with supports at a certain overhead distance).

Our production technology is chosen according to specific criteria such as: nominal diameter, nominal pressure, nominal stiffness and joint type.

fibra vetroresina


Our fiberglass fittings are made up by an initial corrosion and diffusion barrier followed by a resistant mechanical layer, which forms the structural wall of the fitting.
