How long can a metal roof withstand extreme weather?

By Johan Andersson, July 17 2014

A part of our work to develop and improve solutions for roof- and wall is to expose the products in a test facility. The most correct and revealing is to test in the environment the products are used in the reality – instead of accelerated tests in a laboratory environment.

Where do we find the toughest climate?

At Lindab we use one of Swerea’s test facilities at Bohus Malmön, Kvarnvik, situated just a few metres from the sea shore in one of the toughest environments possible. The test station fulfills the demands for RC5 (marine environment) and UV3 (ultraviolet light resistance). It gives us valuable feedback on how our products and solutions will work in reality and greatly aids our product development.

The indicators we measure

The samples mounted at Kvarnvik are there for a time of two to five years and every six months they are measured for:

  • gloss
  • coating thickness
  • color deviation from the original

All kind of visible defects are noted, as for example edge corrosion, blisters under the coating and backside coating behavior. Every year we find out new solutions in the fight for corrosion, experiences which goes straight in to the development of new products and solutions. The test facility is commonly used by companies within the coil coating industry, car industry and infrastructure.
