National Custom Hollow Metal currently manufactures several premium products, including stainless steel, galvanneal, and lead-lined doors and frames. We also now offer Sound Transmission Control (STC doors) that can reduce noise pollution, and Ballistic doors that are capable of stopping a .44 magnum round. But every year DefendDoor custom hollow metal doors and frames continue to be our most popular product line, for many great reasons.

An NCHM, every product built to order by skilled craftsmen in standard and custom sizes. None of our products are ever mass-produced, and we don’t start building them until you place your order. Most importantly, our commitment to customer satisfaction is unrivaled in our industry. From your first phone call to the day that your doors are delivered to your jobsite, we’ll be there every step of the way to make sure that you get the products that you need, when you need them. Here’s a quick look at your options when you place an order for DefendDoor products:

Standard and custom sizes, cores, and labeling-If you can dream it, we can craft it! We can custom build 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. You also have your choice of polystyrene, honeycomb, or vertically stiffened cores, and all DefendDoor products are available with 20 minute, 45 minute, 90 minute, and three hour Warnock-Hersey fire door labeling.

Precision engineering-DefendDoor products 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. The complete unit is closed with 14-gauge steel, perimeter channels, spot-welded at 8″ on center. We also mortise and reinforce our doors with 7-gauge hinge reinforcements, and include 16-gauge box-type lock reinforcements. The doors are durable, attractive, and corrosion-resistant!

Industry leading turnaround on all orders-Every NCHM order comes with Quik Ship service at no additional charge, and we can ship frames in two weeks, and doors in three weeks. And if you’re really facing a tight deadline, we also offer other expedited shipping options.
