Steel

Metal represents the most sustainable
environmentally-friendly building material and
metal rainwater drainage systems contribute
significantly to the sustainable design concept,
thanks to their high recycled content, recyclability
and energy efficiency.
Galvanised steel offers significant advantages
when considering the entire system life cycle. It is
produced from materials that have high recycled
content from both pre-consumer and post-
consumer scrap and can be reused or recycled
repeatedly without losing its qualities as a building
material making it a sustainable choice for low
carbon specification projects. Percentage wise,
the recovery rates of steel is in the high nineties.

The popularity of steel amongst architects has
seen this rainwater system become increasingly
