Heavy Duty Steel Stiffened Doors

B Series stiffened core doors add internal steel stiffeners, extending the full width and height of the door. These doors are designed to meet the architectural requirements for full flush doors, from heavy to 14 gauge maximum duty. Premium standard door construction combines a beveled lock and hinge side, strong epoxy-filled interlock edges, and unsurpassed 7 gauge hinge reinforcement. B Series doors have a higher than normal resistance to impact damage. Overall door construction exceeds ANSI A250.8-2017 (SDI-100), the standard set by SDI specifying sizes, design, materials, construction, finishing, and performance for standard commercial steel doors and frames Hardware preparations and reinforcements meet ANSI A250.6-2003, and locations meet ANSI/DHI A115 unless otherwise stated Doors meet the broadest fire rating requirements; they are listed for installations requiring compliance to both neutral pressure testing (ASTM E152 and UL-10B) and positive pressure standards (UL-10C) Factory-applied baked-on rust-inhibiting primer meets ANSI A250.10-2011
