At National Custom Hollow Metal, The Difference is Quality. For the past four decades, we have been manufacturing custom-built hollow metal frames and doors to order right here in the USA. We don’t mass produce our products in an overseas factory, and every product that we manufacture is subjected to multi-point inspection before shipping. All of our products are guaranteed for 1 year and many outlast the buildings where they’re installed!

The only thing stronger than our doors and frames is our commitment to legendary customer service. We will work with you every step of the way to make sure that the doors and frames that you order meet your exact specifications, and we offer just in time delivery to the jobsite.

Our DefendDoor Doors can be manufactured 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. We offer polystyrene, honeycomb, or vertically stiffened cores, as well as 20 minute, 45 minute, 90 minute, and three hour Warnock-Hersey fire door labeling. The doors are all 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 16-gauge box-type lock reinforcements. We also enclose the complete unit with 14-gauge steel, perimeter channels, 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 they day they were delivered, and you can always count on them fastening smoothly and securely.

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 under normal lead times. And if you’re on a really tight schedule, 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.
