QC Flooring is a composite steel and concrete slab system with a neat ceiling, pre-painted or ready for painting underside. It provides added flexibility in that the cover width may be customised to suit the floor design.
QC panels provide the following features:
Shutter – supporting the mass of the wet concrete and construction loads.
Tensile reinforcement – resulting in a composite section with the concrete.
Finished ceiling – ready for painting with PVA compound QC panels are easy to erect and the system is adaptable to steel, concrete and brick structures. Provision can easily be made for electrical and mechanical services.

Unless otherwise stated by the Engineer, the concrete shall have a minimum cube compressive strength of 25MPa at 28 days. Materials, mixing, placing and curing of concrete shall be following SANS 10100-2: 1992, or following the Engineer’s specification. Concrete used with QC panels shall not contain chloride salts or other deleterious material. No load shall be applied until the concrete has reached its required strength.
Composite Slab Design
Calculations are based on the Limit State Method (SANS 10100-1: 2000).
