Description
Kalzip structural decking provides an economical solution for long span installations and eliminates the need for purlins.
For enhanced acoustic absorption, decking sheets can be perforated and can support mass, such as increased insulation or board, which may be introduced for more rigorous acoustic specifications.
With a choice of steel or aluminium, a selection of profiles, gauges and sheet lengths – this range of products has been developed to extend the versatility of Kalzip, making it suitable for a wide range of applications.
As a general rule, steel is cost effective and provides the optimum in loading and spanning capability; whereas aluminium offers exceptional durability in buildings with high humidity levels such as swimming pools and wet industrial process plants, e.g. paper mills.
Where structural decking is installed there is a reduced requirement for secondary steelwork. The Kalzip structural decking sheet is generally laid transverse to the direction of the Kalzip standing seam roof sheet and spans between the main steel rafters. Typical rafter centres would be approximately 3 to 8 metres.
The Kalzip clips are installed in a diagonal layout so that all external roof loads can be evenly distributed to the structural decking sheet. The frequency of clips may be increased at the perimeter of the building where higher wind loads occur.
The gauge and profile of the Kalzip structural decking sheet is therefore determined by the rafter centres, all external roof loads, internal wind loads, service loads (e.g. lighting) and the dead weight of the construction components.
The complete range of Kalzip 65, 50 and AF standing seam profiles are suitable for use with Kalzip structural decking.
