Stainless steel fire doors in 304/316 with a fire-rated core. Corrosion-resistant, easy-clean and hygienic, Class A (90 min)/B (60 min)/C (30 min). Ideal for food, pharma, hospitals, coastal and cleanroom environments.
A stainless steel fire door is built from 304 or 316 stainless steel leaves and frame with a fire-rated insulating core. It needs no painting to resist rust and corrosion, and is fitted with fire-rated locks, hinges, closers and sequencers to preserve integrity, insulation and smoke control in a fire.
Compared with a standard steel door, the stainless version withstands moisture, corrosion and frequent cleaning while keeping its finish, making it ideal for food, pharmaceutical, healthcare, coastal and cleanroom settings. Graded Class A/B/C with full certification.
Every element, from leaf to frame, is engineered for the stable, long service life of the Stainless Steel Fire Door.
0.8-1.2 mm 304/316 stainless leaves with a fire-rated core; no painting required.
One-piece stainless frame with intumescent seals for smoke control.
Fire lock, fire hinges, closer and sequencer supplied as a matched set.
Edge seals expand under heat to block smoke penetration.
A fire-rated glazed panel for inspection without affecting the rating.
