At National Custom Hollow Metal, The Difference is Quality! We’ve been manufacturing premium quality stainless steel doors and frames in the USA for five decades, and every product we ship is custom-built to your specifications! We offer industry-leading turnaround times on all orders and love partnering with distributors running just-in-time operations. We’ve recently made several new upgrades to our plant to expand our capabilities and offer several great product lines. DefendDoor stainless steel doors and frames have been our top-selling product line since day one, and we can give you a quote in two hours or less!

We can manufacture DefendDoor stainless steel doors to your specifications in 304 or 316 #4 finish in sizes up to 4′ 10 1/4 wide and 12’0” tall and frames up to 10’0” wide and 12’0” tall. You can choose from polystyrene, honeycomb, or vertically-stiffened cores, and we’ll help you determine the most suitable materials for each order. We offer your choice of 20-minute, 45-minute, 90-minute, or three-hour Warnock-Hersey fire door labeling, and our vertically-stiffened doors meet hurricane labeling requirements; we also offer window and louver cut-outs in any size as long as the kit and glass match or exceed the door’s fire rating requirements. Our team members will ensure you get an accurate quote, and we offer industry-leading turnaround times on all orders.

Stainless steel is as durable as it is attractive and outlasts both galvanneal steel and aluminum. It also doesn’t have to be painted and resists oxidation without special finishes. The only thing you’ll ever have to do to keep them looking as great as the day they were delivered is occasionally wipe them down with water!

All NCHM orders include 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 love working with just-in-time operations and offer Hot Rush and Walk Thru service for distributors with rapidly approaching deadlines. Most importantly, we stand behind every order with a 100% satisfaction guarantee!
