We often get questions about comparisons of different materials. Very frequently the choice is between steel versus plastic or aluminum. Our choice at Lindab is, and has always been, steel. We will give you 5 real reasons to choose steel for your rainwater system rather than PVC or aluminum. 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.
