DefendDoor stainless steel doors are high-quality center-seamed box doors suitable for any office space or commercial center. We also offer optional fully seam-welded vertical, or three or four-sided seam-welded box doors suitable for food preparation and healthcare facilities. Defendoor products are available in your choice of 304 or 316 #4 finish, and they’re rust-prohibitive and corrosion-resistant. They never need to be painted, and the only long-term maintenance you’ll ever have to do is to occasionally wipe them down with soap and water!

We can manufacture DefendDoor stainless steel doors to your specifications 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 can also help you meet most labeling requirements, including Underwriters’ Laboratories labeling and 20-minute, 45-minute, 90-minute, or three-hour Warnock-Hersey fire door labeling. All of our products are thoroughly cleaned and finished at our factory, and will be carefully crated for damage-free delivery. We include free Quik Ship service on all orders, with a standard turnaround time of one week for frames and two weeks for doors. And if that’s not fast enough, we also offer expedited shipping options, including Hot Rush and Walk Thru service. Just let us know when you need your doors shipped, and we’ll take care of the rest!

The Difference is Quality at NCHM, and you can always order with confidence because we stand behind all of our products with a one-year warranty!
