Model: SFD 503
Fire rated door in SS 304 or SS 316 for hospitals, cleanrooms, food and chemical storage — corrosion resistant, easy to clean, up to 180 minutes.
Where a painted door will not survive — hospital corridors under daily disinfection, cold and wet storage, chemical stores — the SFD 503 uses stainless steel grade 304 or 316 faces. The construction matches the SFD range: mechanically interlocked, hemmed vertical edge seams with inverted top and bottom channels welded to both face sheets.
According to our catalogue data the door offers acoustic performance of up to 32 dB and thermal characteristics of U-factor 0.41 and R-factor 2.44, which makes it a good choice where temperature or noise separation matters as much as fire separation.
Single and double leaf configurations are available in the standard SFD size range, with vision panels and hospital hardware specified per room.
