National Custom Hollow Metal has been manufacturing premium stainless steel doors and frames right here in the USA for over four decades, and The Difference is Quality. We don’t mass produce doors in an overseas factory and ship them in a stack of containers. Every product that we manufacture is subjected to multi-point inspection before shipping, and we take pride in our commitment to craftsmanship. We will work with you every step of the way to make sure that your order is perfect, and built to meet your exact specifications. We also offer quotes in two hours or less, and expedited shipping options to deliver directly to your jobsite.

We offer several product lines including our TrustShield Lead-Lined doors and frames, SafeShot Ballistic Doors, and custom solutions including pocket doors. But our DefendDoor line of custom stainless steel doors and frames continue to be our top seller. We can manufacture DefendDoor Doors in sizes up to 4′ 10 1/4 wide and 12’0” high in either 304 or 316 #4 finish, and frames up to 10’0” wide and 12’0” high.

All DefendDoor doors are internally reinforced with continuous 16 gauge stainless steel rails that span the entire height of the door on both the hinge and lock stiles, and across the top and the bottom. We also mortise and reinforce our doors with 7-gauge hinge reinforcements, and include 14 or 16-gauge box-type lock reinforcements. We enclose the complete unit with 14-gauge steel and perimeter channels that are spot-welded at 8″ on center to guarantee a finished look. The DefendDoor line of stainless steel doors and frames are as attractive as they are durable, and corrosion resistant. An occasional rinse with water will keep them looking as new as the day they were delivered.

If you need to meet labeling requirements, we offer several options including 20 minute, 45 minute, 90 minute, and three hour Warnock-Hersey fire door labeling. You also have your choice of polystyrene, honeycomb, or vertically stiffened fiberglass insulation filled cores.

All orders from NCHM come with free Quik Ship service, and you can expect your frames to be shipped in two weeks, and your doors to be shipped in three weeks. We also offer expedited delivery options.

If you have any questions, or would like to receive a quote on doors and frames in two hours or less, contact us online, or give us a call at 800-334-3070.
