Attractive. Stable. Durable.

The colour and zinc-magnesium finishing for extreme resilience and maximum corrosion protection are persuasive features of the Zambelli Master System. Whether it’s rain gutters, downpipes or accessories, all roof drainage components in the Zambelli Master series are made from the same primary material to guarantee a completely uniform surface.

Galvanized steel has proven its worth in metalworking for the construction industry thanks to its excellent strength and permanent corrosion protection. A roof drainage system made of galvanised steel absorbs high wind and snow loads. In addition, the linear expansion is lower compared to zinc, copper & co.
