At National Custom Hollow Metal (NCHM), quality isn’t just a promise—it’s guaranteed! For more than five decades, we’ve been crafting premium stainless steel doors and frames right here in the USA, and they’re all custom-built by the most skilled craft professionals in the industry. DefendDoor stainless steel box doors are the ideal choice for any building where cleanliness is a must, and we’re ready to give you a custom quote in two hours or less.

Unlike traditional welded doors, DefendDoor box doors feature seamless construction, so you won’t have to worry about microbial bacteria lurking away in hard-to-reach areas. We can build box doors to your specifications from your choice of Stainless or Galvaneal steel, and they’re a cinch to clean. The only thing you’ll ever have to do to maintain their factory-new appearance is to wipe them down occasionally with water!

At NCHM, we strive to understand our clients’ projects and deliver solutions tailored to their unique needs. Like all our products, our box doors are built to order and undergo a meticulous, multi-point quality assurance inspection before being carefully crated for shipping. Our box doors with honeycomb cores are also available with 20-minute, 45-minute, and 90-minute Warnock-Hersey fire labeling! The only information we’ll need to get started on your quote is the dimensions of the door, your labeling requirements, and your desired delivery date.

All NCHM orders include free Quik Ship service with standard delivery times of one week for frames and two weeks for doors. And if you need your doors shipped faster than that, we also offer expedited shipping options, including next-day Walk Thru service! Just let us know when and where you need your box doors delivered, and we’ll handle the rest.

At NCHM, we go beyond simply delivering stainless steel products—we provide solutions tailored to your specific project needs. Every DefendDoor stainless steel door and frame is attractive, durable, and virtually maintenance-free, and you can always place your order with confidence because we stand behind all of our products with a one-year warranty!
