STRUCTURAL PERFORMANCE


The effect of gauge on pre-finished steel roof


The structural performance of pre-finished steel cladding is determined by the profile of the cladding, the mechanical properties of the steel substrate and the gauge of the pre-finished steel.


Confusion can sometimes arise with regard to measuring and describing the gauge of pre-finished steel coil and sheet used in roof and wall cladding systems.


How to measure gauge


Pre-finished steel products are made up of a number of layers, which provide a durable and aesthetic product.


The actual gauge of the product is measured using a micrometer, to include the steel substrate and the metallic coatings, but excluding the paint and primer layers.
