50-year durability statement

Our cold formed structures are coated with a Z450 galvanised coating, providing a 50-year durability offered by the manufacturer – NZ Steel. This is twice as much as our nearest competitors who use a Z275 galvanised coating which provides only 25-year durability. Other competitors are less again. All of our buildings have a design life of 50 years, subject to the agreed design parameters in conjunction with a maintenance programme.
