National Custom Hollow Metal recently celebrated its 50th year of continuous operation, and we owe our longevity to repeat business. We believe in forming lifetime partnerships with our distributors, and you can always count on legendary service after the sale! We proudly offer several lines of custom-built stainless steel doors and frames, including TrustShield lead-lined doors, Sound Transmission Control (STC) doors, and energy-efficient kerf frames. Our original line of DefendDoor doors and frames continues to be our top-selling product line, and we’re ready to give you a quote in two hours or less!

Stainless steel outlasts galvanneal steel and aluminum and is an ideal material for exterior and interior doors. DefendDoor stainless steel doors resist oxidation without special finishes and never have to be painted. They’re beautiful and durable, and the only long-term maintenance you’ll ever have to do is occasionally wiping them down with water!

We can manufacture DefendDoor stainless steel doors in 304 or 316 #4 finish in any size up to 4′ 10 1/4 wide and 12’0” high and frames up to 10’0” wide and 12’0” high. We offer your choice of 20-minute, 45-minute, 90-minute, or three-hour Warnock-Hersey fire door labeling, as well as UL labeling and vertically-stiffened doors that meet hurricane labeling requirements. You can choose from polystyrene, honeycomb, or vertically-stiffened cores, and we’ll help you determine the most suitable materials when you place your order. We can also customize your doors with window and louver cut-outs in any size as long as the kit and glass match or exceed the door’s fire rating requirements.

Like All NCHM products, DefendDoor stainless steel doors and frames are all custom-built and subjected to a rigorous multi-point quality assurance inspection before shipping. With our Quik Ship service, you can expect your frames to be shipped in two weeks and your doors to be shipped in three weeks. And if that’s not fast enough, we also offer expedited shipping for our distributors who have rapidly approaching deadlines. Most importantly, you can always order with confidence because we stand behind every product we sell with a one-year warranty!
