Voidcon- Innovative Permanent Formwork
Voidcon is an economical, innovative permanent formwork system that, combined with concrete, acts as a composite suspended slab.
About Voidcon
The Voidcon Permanent Formwork System, launched in 2004, is a composite suspended slab system proudly manufactured by Clotan Steel.
Voidcon is a 100% patented South African product, and is designed, manufactured, and distributed nationwide in South Africa and boasts a variety of structural projects across the African continent.
Voidcon keeps building innovation on top of mind; offering a lighter, more cost-effective, and environmentally friendly building system compared to conventional concrete slab building methods.
The Voidcon system offers:
• Design flexibility for designers, developers, and architects. • Cost efficiency, and lightweight product features.
How does the Voidcon Permanent Formwork System work?
The Voidcon Permanent Formwork System is manufactured, utilising galvanised steel profiles, laid in position as panels. These panels once laid into position acts as formwork for wet concrete to be poured over the profiled galvanised panels. The concrete provides strength, and together with the steel provides higher stability.
The Voidcon Permanent Formwork System can be used on any design– curved or straight. It has been used in design application for factories, warehouses, shopping malls, office blocks and blocks of flats.

Why choose Voidcon for my next floor/slab project?
- The Voidcon Permanent Formwork System uses less concrete than conventional decking systems, resulting in substantial project cost savings.
- Installing a Voidcon Permanent Formwork System is more economical and effective featuring quicker installation methods, in high quality soffit finishes.
- The Voidcon Permanent Formwork System utilises the patented T-Beam design, in return the system uses less concrete and steel, therefore making it substantially less harmful to the environment.
- The concrete and steel combination provides strength and stability – while the concrete is strong on compression, steel is strong on tension. The result is the profile and concrete forming an indestructible bond, providing exceptional composite action.
- Clotan Steel can, through its more than 30 years of export experience, deliver the Voidcon system across the African continent and further afield.
- The Voidcon system requires minimal propping and is ideal for use in use of complicated shaped slab design requirements. Voidcon is designed to carry uniformly distributed loads.
- The Voidcon system offers sound and temperature insulation.
