Stainless Steel Fire Door
STS stainless steel fire doors are precision-manufactured from 304/316 stainless steel using advanced sheet-metal processing technology. The door leaf is filled with a fire-resistant mineral core, achieving fire ratings from A30 to A180. The corrosion-resistant surface (mirror #8, brushed #4, hairline or satin finish) requires minimal maintenance and meets the stringent hygiene requirements of medical facilities and clean rooms. Each door is fitted with fire-rated stainless steel hardware including lockset, hinges and door closer, and is certified to both UL and 3C standards.
