Rotting timber. Warping composite. Popping screws. If your decking is failing, the iFrame steel system with porcelain paving is the permanent solution: no more 5-year replacements.
The Problem
That “25-year warranty” composite decking? Here's what the brochure doesn't tell you.
The top 3mm of your timber joists are constantly wet through winter. The wood slowly softens and deteriorates from the inside out.
Wood-chip composite heats up to 30°C+ on sunny days and wants to expand. The boards push against each other with enormous pressure.
The screws holding your boards down are now fighting two forces: expanding boards above and rotting timber below. Something has to give.
The result: boards lifting at the edges, gaps appearing, surfaces becoming uneven and unsafe. Even premium American timber-tech products fail this way.

The cycle repeats every 5–8 years with timber and composite.
The Solution
The iFrame system replaces your entire decking structure with cold-rolled galvanised steel: then finishes it in porcelain paving that lasts decades.
Cold-rolled galvanised steel. No moisture absorption, no deterioration, no failure. Structurally stable for decades.
Zero thermal expansion. No buckling in summer, no cracking in winter. Frost-proof, UV-stable, maintenance-free.
Water passes straight through the joints and drains away naturally. No puddling, no channelling, no algae build-up.
No concrete, no wet trades, no curing time. Your old deck comes out and the new system goes in: typically 3–5 days.
Your old composite goes to landfill. Our steel is fully recyclable. Better for you, better for the planet.
For raised or sloped areas, iFrame + porcelain often matches or beats traditional elevated paving costs.

If I had my traditional patio, I'd be out here pulling weeds and brushing every weekend. Now I just jet wash it back to brand new. There's no maintenance at all. It's the best thing I've ever done.
