The DefendDoor line of custom-built stainless steel doors and frames from National Custom Hollow Metal continue to be our top seller for many great reasons. At NCHM The Difference is Quality, and you can always count on precision craftsmanship and doors that are built to last. They’re also built to order! We don’t mass-produce doors and let them sit stacked on pallets in a warehouse. When you call us for a custom quote on DefendDoor products, you can also receive a custom quote in two hours or less!

DefendDoor Doors can be built in any 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.

We offer several labeling options for DefendDoor products 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. The doors and frames are as attractive as they are durable and practically maintenance-free!

We take pride in our commitment to craftsmanship, and all of our products are manufactured right here in the USA. Every product that we manufacture is subjected to multi-point inspection before shipping, and we guarantee that your order will be built to meet your exact specifications and shipped on schedule. All NCHM orders include 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 when normal lead times are available. We also offer expedited delivery options when you need your doors in a hurry!

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.
