HIGH QUALITY HOLLOW METAL DOORS

60+ YEARS SUPPLYING, INSTALLING & REPAIRING HIGH QUALITY HOLLOW METAL DOORS

At Capitol Fireproof Door our hollow metal doors are made of the highest quality open-hearth, cold-rolled, pickled, patent-leveled sheet steel. Every door is engineered to meet or exceed the architectural requirements for full flush doors.

  • The inner core can be honeycomb paper or 22 gauge inverted hat shaped steel ribs, welded to outer face sheets running 6” on center throughout the door.
  • Continuous bonding of core to metal face sheets.
  • Rock wool insulation fills gaps between ribs.  Rock wool is packed to a specific density so as to act as a sound deadening material.
  • Doors are mortised and reinforced for any type of hardware.
  • Flush doors can be fabricated of 12, 14, 16, 18 or 20 gauge steel.
  • Seamless, galvanneal manufacturing with top and bottom closed is available.
  • All exposed surfaces are clean and can be finished with one coat of metallic primer.
