GRP pipes and fittings

GRP pipes and fittings under pressure and gravity


Composite materials:

  • glass fiber
  • polyester resin
  • silica sand


The composition of fiberglass – GRP pipes and fittings allows for superior properties in terms of performance, quality and cost-effectiveness compared to conventional materials.

  • High resistance to corrosion
  • Lightness and elasticity of the structure
  • Excellent hydraulic properties
  • Long service life
  • Environmentally friendly product
  • Highly resistant structure
  • Low operating and maintenance costs
  • Easy and fast installation
  • Adaptability to ground movements
  • Low transportation cost
  • High resistance to chemical agents

The chemical resistance varies depending on the type of resin used; pipes are specially designed according to the chemical temperature and the fluid to be transported.


Pressurized and non-pressurized, GRP pipes are used for drinking water, irrigation water and sewage systems.

Specifically for:

  • Irrigation distribution networks
  • Drinking water distribution networks
  • Sewerage networks, treatment plants
  • Rainwater drainage networks
  • Power plant connection lines
  • Industrial lines
  • Road crossings
  • Renewal of existing pipelines by pushing
