Profiling Sheet Information

Metal profile sheets are metal structural members that due to the fact they can have different profiles, with different heights and different thickness, engineers and architects can use them for a huge variety of buildings, from a simple industrial building to a high demand design building. Trapezoidal profiles are large metal structural members, which, thanks to the profiling and its thickness, retain their high load bearing capability. They have been developed from the corrugated profile. The profile programme offered by specific manufacturers covers a total of approx. 60 profile shapes with different heights. Cassettes are components that are mainly used as the inner shell in dual-shell wall constructions. They are mainly used in walls today, even though they were originally designed for use in roofs.

The primary function of the cladding system is to provide a weathertight building envelope, suitable for the intended use of the building. Trapezoidal metal roof sheets with through fix fasteners are generally suitable for slopes of 4% or steeper. This limit is critical to the performance of the cladding. For shallower pitches, down to 1.5%, a fix system with no exposed through fasteners, special side laps and preferably no end laps should be used. For low pitch roof, ponding is a potential problem that must be considered at the design stage in order to avoid the deleterious effects of prolonged soaking and the increased loading, due to the weight of the water.
