We often get questions about comparisons of different materials. Very frequently the choice is between steel versus plastic or aluminium. Our choice at Lindab is, and has always been, steel. In this blog post I will give you a few of the reasons to choose steel for your rainwater system rather than PVC or aluminium.
Most of these arguments go for all steel systems, but we think that we add even more to this fantastic material. We have been processing steel for more than 50 years and we buy over 200 000 tonnes of steel every year, so we feel that we know what we are doing. We also put our products through rigorous testing. Something you can read more about in one of our previous posts.
1. Steel has the lowest carbon footprint of all rainwater systems materials
With steel you get a cost effective and environmental friendly installation that is 100 % recyclable. Our Rainline system is made from sheet steel, a raw material that has a natural place in today’s approach towards sustainability.
2. Steel stays in shape
Virtually all materials are affected by differences in temperature and grows and shrinks as the weather changes. Compared to aluminium and plastic, steel has a lot smaller movement factor. This means that your installation is much more likely to last as connections and fixation points won’t take such a beating as with other materials.
3. It’s really long lived
A rainwater system made of steel can last in excess of 70 years. To aid to the lifespan we rustproof the material with a 275 grams zinc coating. This gives the system a self-healing quality where scratches and cuts are automatically sealed by zinc ions that migrate to re-coat the uncovered steel.
4. Strong as steel
Steel is the foundation of all modern construction, and there is a reason for that. Steel is strong. Snow, hail, falling tree branches and other circumstances can easily break a rainwater system made from aluminium or plastic materials. And even though we recommend that you are careful during the installation, a steel system is much more heavy duty than its competitors.
