DefendDoor box doors are ideal for healthcare, food service, and clinical research facilities where cleanliness is absolutely necessary. Unlike traditional welded doors, our box doors feature seamless construction, so you won’t have to worry about microbial bacteria lurking away in hard-to-reach areas. They’re a cinch to clean and sanitize, and the only thing you’ll ever need to do to keep your doors spotlessly clean is to wipe them down occasionally with water or your preferred cleaning product.

We can build DefendDoor box doors to your specifications from Stainless or Galvaneal steel, and we also offer your choice of 20-minute, 45-minute, and 90-minute Warnock-Hersey fire labeling when you order box doors with honeycomb cores. We perform a rigorous multi-point inspection before your doors are carefully crated and shipped, and all orders include free Quik Ship service with standard delivery times of one week for frames and two weeks for doors. We also offer expedited shipping for our distributors wth rapidly approaching deadlines, including Walk Thru service with turnaround times as quick as one day! Let us know when and where you need your doors, and we’ll take care of the rest!
