Product Description
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.
Why specify a Stainless Steel Fire Door? Six values that matter most.
304/316 stainless resists moisture and rust - first choice for coastal and humid sites.
Smooth, seamless surface suits food, pharma and cleanrooms.
From 90 min upward, effectively blocking fire and smoke.
Tested and certified, ready for compliance and inspection.
Keeps its metallic finish with no coating to peel.
Does not rust, so day-to-day care is minimal.
