Steel Security Doors FAQ

Does installing a steel door add security to a building?

Absolutely! Our steel doors are virtually indestructible. The strong zintec steel door and frame offers exceptional strength. Quality hardware and locks protected by the anti-jemmy strip provide a secure barrier to unauthorised entry.

Are MDM steel doors made of solid steel?

No. Our steel doors comprise of a composite core enclosed within a hollow zintec steel skin. A solid steel door would be prohibitively heavy and would most likely tear out the hinges. Zintec steel is used for the skin of the door. The door is hung within a zintec steel frame. None of the core is visible on the edges of the door.

What is the reason for the steel doors’ non-metal core, other than the weight factor?

Remember that steel, and most metals, are remarkably good conductors of heat and cold. This is not something that you want for a door. So the cores act as thermal barriers. In fact, studies show that these man-made materials are 500% better at blocking unwanted heat and cold then are solid wood doors. The core also adds strength to the hollow metal door leaf.
