PREFA gutters have been tried and tested for decades and their appeal lies in their well-thought-out, detailed technical solutions. Thanks to the proven surface treatment, they remain functional and attractive for many years. PREFA gutters are produced from powder-coated aluminium strips. Alloys according to EN 573 or DIN 1725 make up the basic material for this.
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.
