UL Fire-Rated
NAAMM/HMMA Compliant
Soft segmented arch doors provide specialized architectural openings for commercial and healthcare facilities requiring curved frame profiles. Engineered in stainless or A60 galvannealed steel in 18 to 12 gauge, these hollow metal assemblies offer UL fire-rated protection, NAAMM/HMMA compliance, and versatile core options including polystyrene, polyurethane, steel-stiffened, and temperature rise cores.


Soft segmented arch doors and frames are fabricated in steel gauges ranging from 18 gauge to 12 gauge. This thickness range allows project managers and contractors to select lighter gauges for standard commercial interior openings or heavy-duty 12 gauge steel for demanding, high-traffic commercial building applications requiring structural rigidity.
