Information

Aluminium does not rust. In addition, PREFA uses a special salt-water-resistant aluminium alloy on its gutters. If the surface becomes damaged, the plain aluminium reacts with oxygen to form a permanently protective oxide layer which protects the gutter from any further damage. Aluminium is also a fully recyclable material. It can be 100% recycled in an energy-efficient way, without loss of quality.

Advantages of PREFA gutters:

  • corrosion-free and long service life due to aluminium
  • tested original quality
  • can be used creatively thanks to a range of 12 colours plus additional special colours (on request)
  • maintenance-free
  • comprehensive gutter accessories

Notes

  • The RAL values stated are merely approximate values (~), some of which may differ vastly from the original PREFA colour and, under certain circumstances, may not reflect the subjective perception of the colour. 
  • Above all for colour quality P.10, it is almost impossible to define values due to the surface structure.
  • Plain aluminium: The guarantee does not cover surface appearance alterations caused by processing and environmental influences. Follow the instructions.
  • Metallic colours may vary in shade.
  • To identify exact colours for complementary components please consult original samples.
