on-roof gutter

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.

The coating layer is malleable and protected against general chemicals and weather conditions. The coil-coating process is subject to strict quality controls.

In addition, the long-term behaviour is analysed in salt spraying, condensation and water immersion tests.
