Model: SFD 502
Double-leaf fire rated steel door for wide openings — up to 180 minutes, 50 mm leaves, sizes from L 1500 to L 2200 mm, with panic hardware and vision panels.
The SFD 502 handles the wide openings that single doors cannot: loading corridors, main stair lobbies, production-floor exits and plant rooms that need equipment access. Both leaves share the SFD construction — 50 mm thick, 1.2 mm cold-rolled steel skins, honeycomb or rock wool core — and the assembly is rated for up to 180 minutes.
Double doors are where hardware matters most. We supply them with UL-certified stainless steel hinges, imported smoke seals around the frame, and can fit UL-marked panic exit devices, closers and door coordinators so both leaves close in the right order. Vision panels use 6 mm tempered glass with a standard exposed area of 450 × 150 mm.
Standard double-leaf sizes run from L 1500 × H 2100 mm to L 2200 × H 2400 mm. Tell us the clear opening and the door handing and we will confirm the leaf split.
