What Can You Build With SFS?
Steel Framing System (SFS) isn't just for commercial partitions. It's rot-proof, vermin-proof, fire-rated, and dimensionally stable — which makes it the ideal frame for dozens of structures a timber frame simply can't match. From garden bars to pool plant rooms, here's what's possible.
Rot-Proof
No decay, no swelling, no warping. Ever.
Vermin-Proof
No nesting, no chewing, no infestation.
Fire-Rated
30 to 120 minutes, without the fight timber gives you.
C5 Available
The only genuinely corrosion-proof framing for wet environments.
Dimensional
Every stud identical. No shrinkage, no sagging.
Fast
Bolt-together logic. Minimal site time.
✓Why SFS Beats Timber
The reasons most garden and light-commercial builds are better served by SFS than a traditional timber frame.
