Secure open units or sheet metal parts against falling in strong winds.
Protect cardboard packaging stored at the building site against rain with a tarpaulin. Gutters and pipes are covered with a protective film for protection during transport. UV radiation can make it difficult to peel off the protective films. Therefore, ensure that gutters and pipes are not stored in direct sunlight (UV radiation).
Inlet plates/ice strips guide water into the gutter and prevent water from splashing onto the back of the gutter. The need for drip edges or starter plates depends on the positioning of the gutter and local requirements and is object-related in coordination between the architect, installer and client. Country-specific requirements must be taken into account.
Painting over or repairing scratches on PREFA roof drainage products is not required due to the corrosion resistance of aluminium. When touching up scratches, there may be colour differences due to different paint qualities of the touch-up paints/pens.
The forming of powder-coated products (e.g. widening of pipes) may lead to cracks and damage to the coating.
