At National Custom Hollow Metal, we offer the industry’s best selection of custom hollow metal doors, with a variety of premium product lines. Year after year, our top-selling product line is DefendDoor! DefendDoor doors and frames are always built to order, and offer the perfect blend of both form and function.

When you’re looking for the highest quality stainless steel doors and frames in the industry, you owe it to yourself to insist on DefendDoor. Here are three big reasons DefendDoor continues to be our top seller:

1. Unrivaled Strength and Durability-All doors are 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. The complete unit is closed with 14-gauge steel, perimeter channels, spot-welded at 8″ on center. We also mortise and reinforce our doors with 7-gauge hinge reinforcements, and include 16-gauge box-type lock reinforcements. You can always count on every DefendDoor product to give years of dependable service, and they will outlast the building in which they’re installed. And all that you have to do to maintain their factory-fresh appearance is occasionally wipe them down with water.
2. Unlimited Customization Options-Every DefendDoor product is custom-built to your specifications, and you will never receive something that was mass produced and sat for months in a warehouse. We can build doors 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. You can pick from polystyrene, honeycomb, or vertically stiffened cores, and all DefendDoor products are available with 20 minute, 45 minute, 90 minute, and three hour Warnock-Hersey fire door labeling.
3. Lightning Fast Shipping -We offer a fast lead time on all orders, and can ship frames in two weeks, and doors in three weeks. But if you’re really in a hurry, we also offer expedited shipping, including Hot Rush service where we can ship doors in five business days, and frames in three business days, and Walk Thru service where we can ship frames as early as the next business day and stainless doors in 3 days.
