Frabopress C-Steel Big-Size

FRABOPRESS C-STEEL BIG-SIZE is the ideal solution for any type of water supply and distribution system, and it is widely used both in big civil and industrial installations thanks to its corrosion resistance, healthiness, reliability and quick assembly. The system allows the connection of carbon steel pipes complying with EN 10305-3 standard with the diameters 76.1 mm, 88.9 mm and 108 mm

Connections with other systems are made possible by flanged couplers with a pressfitting female end. Flanges are available in PN10 or PN16 version.

For more detailed information on products installation and fields of application, it is necessary to refer to the technical data sheets available in the DOWNLOAD section of the website.

Pipes to be used

The system pipes are electro-welded using hot zincplated strip with an extra layer of zinc over the soldering. They are therefore zinc-plated inside and outside, hence guaranteeing maximum protection against corrosion. Pipes with only outside galvanisation are also available.

Standards compliance

  • UNI EN 10226-1
  • UNI EN 10305-3
  • UNI EN 11179 Classe 1


Not suitable for drinking water

  • Quick cold connection
  • Performance that can cover a large number of civil and industrial applications
  • Installations carried out with FRABOPRESS C-STEEL BIG-SIZE do not need any further pipe protection or painting (with the exception of the envisaged insulation activities)
  • Excellent behaviour of the material against ageing, sunlight, weather
  • Speed of operation, saving time and offering increased productivity levels
  • Gaskets can be fitted without welding, eliminating the risk of fire in more hazardous situations (working in older buildings, furnished rooms, etc.)
  • No need for dangerous gas pumps or containers, completely eliminating the need to make the connections required by law
  • Elimination of all welding materials, with inevitable cost benefits
  • Junctions free from burning or rings with an excellent immediate visual impact
  • Integrity of pipe insulation thanks to the absence of heat sources
  • Increased wall thickness to ensure the reliability and durability of junctions and fittings
  • Polygon-shaped press designed to ensure maximum resistance to traction and torsion stresses
  • Precision cleaning of internal surfaces to eliminate oily residues due to processing and to ensure protection against rust under all operating conditions
