Fire safety is no accident, which is why building codes mandate the installation of fire doors to protect all occupants. During a fire, the doors compartmentalize the affected area to isolate the smoke and flames, and buy the occupants the time they need to exit the building safely.
At National Custom Hollow Metal, we’re well-known for our popular DefendDoor stainless steel doors and frames, as well as our TrustShield lead-lined doors and frames. Our award-winning team is always standing by to build all the custom doors and frames that you need, and ship them to you in a flash. But did you know that we also manufacture pocket doors and arched door frames?
