Internal steel stiffeners extend the full door width to ensure B18, B16 and B14 Series flush doors meet architectural requirements and industry standards for full flush and steel-stiffened doors. Stiffeners are welded to the door face sheets and bonded to the opposite panel, bolstering strength and durability. Full-height, epoxy-filled mechanical interlock edges provide structural support and stability.
Beveled hinge and lock edges allow tighter installation tolerances, ensure easier operation and eliminate binding and sticking. The B Series doors are 1-3/4” (45mm) thick and offer a wide range of specifiable options covering sizes, glass light designs, edge constructions and mechanical, pneumatic and electrical hardware preparations.
Filled seam: optional edge seam epoxy filled and finished smooth; includes tack welds above and below edge cutouts for hinges, locks and more
Welded edge s¬eam: optional edge seam welded with 1” (25mm) long weld, 2” (51mm) on center, epoxy filled between welds and finished smooth; available on B18, B16 and B14 doors
