Premium Steel Flush Doors

L Series flush doors are designed to meet the architectural requirements for full flush doors, from light 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.

• 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
• The continuous bonding of the laminated core to steel face sheets provides an attractive, flat door, free of face welding marks.
• Tests have proven that the L Series door has a high resistance to impact damage, low thermal conductivity, and high STC ratings.
