    Commercial Hollow Metal Door and Frame, 20 Gauge Honeycomb Core Door with 16 Gauge Drywall Knock Down Frame, Lever Lock, Made in New York City

    Universal Fireproof Doors commercial hollow metal steel doors are the highest quality in the industry. Manufactured from heavy-duty 20 gauge steel, these doors are designed for installation in any commercial building. The drywall door frame is shipped in knockdown form and assembled very quickly. The drywall frame is designed to wrap around an interior wall with drywall. The drywall frame is manufactured from heavy-duty 16 gauge steel and provides a durable structure for the hollow metal door.

    Commercial Grade - 20 Gauge Steel Door & 16 Gauge Steel Frame

    Universal Fireproof hollow metal doors are manufactured per order and designed specifically for use on commercial buildings. When we say commercial grade, we mean it. Our doors are manufactured from thick 20 gauge heavy-duty steel, and the door frames are constructed from 16 gauge steel. This is the industry standard for any hollow metal door and frame used in any commercial building, and it offers the best security. Unfortunately, many residential-grade open metal doors on the market today are advertised as commercial-grade. Many of these residential-grade steel doors purposely do not specify the gauge of steel the door is constructed from. The harsh reality is that if the door's steel gauge is not advertised or listed, it is most likely built from thin 24 or 26-gauge steel with no insulated core and designed for residential light-duty homes. When residential steel doors are installed in a commercial building, the metal doors dent and deform within days of installation. The thin gauge residential grade steel provides much less security than a commercial grade 20 gauge steel door. You will not have this issue with our hollow metal door system. Universal open metal doors feature heavy-duty 20 gauge steel with an insulated honeycomb core, lock reinforcement, and hinge reinforcement. Our frames are designed using 16 gauge steel, so they will not bend or dent easily.

    Best Value For Security

    Universal hollow metal doors are ideal for security doors. Unlike wood or aluminum glass doors, steel doors provide more security and durability. Wood doors often crack, and storefront glass doors are vulnerable to broken glass. If your commercial building is in an area subject to abuse or break-ins, the Universal commercial steel door is your best option with the best value. Heavy-duty door construction and frame are much more durable than aluminum or wood. Steel doors also have a much higher impact resistance than commercial wood or storefront doors.

    Energy Efficient

    Our hollow metal steel doors come standard with an insulated honeycomb core. This core type helps retain your commercial building's energy.
