The effect of gauge on pre-finished steel roof and wall cladding performance

This Colorcoat® technical paper advises on the relevant standards and tolerances which should be used and how they should be applied. The properties of the profiled pre-finished steel cladding can be affected by the choice of the nominal gauge and the impact of this extends beyond basic structural implications. This technical paper seeks to explain this along with any limiting criteria which must be satisfied. This paper combines knowledge from Tata Steel and the Steel Construction Institute (SCI) with practical considerations from leading pre-finished steel profilers.
