DefendDoor stainless steel doors are high-quality center-seamed box doors engineered to meet the strict requirements of pharmaceutical, food service, medical, government, and education facilities. All DefendDoor products are custom-built to your specifications in 304 or 316 #4 finish and shipped on your schedule; we can manufacture DefendDoor stainless steel doors in both standard and custom sizes 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 manufacture your doors to suit most labeling requirements, including Underwriters’ Laboratories labeling and 20-minute, 45-minute, 90-minute, or three-hour Warnock-Hersey fire door labeling. And if you’re building in a coastal area, we offer vertically-stiffened doors to help you meet your hurricane labeling requirements.

Stainless steel is beautiful and durable and outlasts both galvanneal steel and aluminum. Your doors won’t have to be painted, and they’re also corrosion-resistant. In fact, the only long-term maintenance you’ll ever have to do is to occasionally wipe them down with water!

We offer coast-to-coast shipping, and all orders include free Quik Ship service. We can ship most frames in around two weeks and most doors in three weeks, and if that’s not fast enough, we also offer expedited Hot Rush and Walk Thru service. Let us know when and where you need your doors, and we’ll ensure that they’re carefully crated and shipped on schedule! DefendDoor stainless steel doors and frames have been our top-selling product since day one, and you can order with confidence because we stand behind all orders with a one-year warranty!
