STAIRFORGE — FORGED TO FIT.

BESPOKE FIRE ESCAPE STAIRCASES. FORGED TO FIT.

An external fire escape has one job above all others — provide safe, code-compliant emergency access, whatever the weather throws at it for the next fifty years. Every staircase is engineered to UK Building Regulations Part K, fabricated from corrosion-resistant steel in our London workshop, and installed with full structural documentation for building control sign-off.
