Design, manufacture and assembly of Protec light gauge steel framing systems

Protec was developed to meet increasing demands for off-site fabrication using more environmentally friendly-methods. Stoneguard’s investment in this state-of-the-art technology is the natural complement to our existing cladding and finishing skills / experience.

All Protec light steel framing systems and structures are underwritten by independent structural engineers and comply with all building regulations. Installation is carried out by our fully-trained team or approved and trusted contractors.

Computerised design and manufacture

Using state-of-the-art computer-controlled design and construction technology, Protec light steel frames are at the forefront of off-site manufacture. Lightweight galvanised steel components are precision-engineered to exact tolerances with an accuracy of better than 1mm. Shaping and cutting is performed by a fully-automated, highly portable computer-controlled rollformer.


On-site assembly of Protec systems is simple, highly efficient and safe. There are no wet processes, cutting or welding, and only minimal waste. Numbered components mean previously untrained personnel get up to speed quickly.

Prelims costs are slashed. As each storey is completed the flat-pack materials can be quickly passed up to the next storey.
On larger projects it is often prudent to set up a small on-site production facility to reduce transport costs (both in terms of money and carbon emissions).
