Light steel cladding

Built up system with liner sheet

These systems comprise two separate cladding sheets: an external sheet, which is coloured and highly profiled, and a more lightly profiled inner liner sheet. The sheets are separated by spacer rails and insulation. The liner sheet and spacers are fixed to cladding rails that span between columns. The external sheet is fixed to the spacer. The normal method of attachment is by self-drilling, self-tapping screws.

Built up system with liner trays

Liner trays span between columns and replace the liner sheet, cladding rails and spacer rails. Insulation is set within the liner trays and the external cladding sheet is fixed directly onto the outer flanges of the tray.

Composite panel system

Composite panels have a sandwich construction comprising two steel sheets bonded either side of an insulating core of foam, mineral fibre or similar material. The bonded panel produces good stiffness, and both profiled and smooth surfaces are available. Panels may be fixed using a variety of techniques including self-drilling, self-tapping screws, and secret fixing brackets located within the panel joints.
