Keep Your Premises Secure with Metal Security Doors

Posted on 18/07/2017

We supply a wide range of Metal Security Doors – all of which are built to the highest standards. If your commercial or industrial premises is unoccupied at night, you want to be certain that it is as secure as humanly possible. Doors provide possible entrance points to unwanted intruders. A locked Steel Security Door from Cooks Industrial Doors Ltd will ensure the casual burglar looks for an easier option elsewhere.

The Door


The door is 48mm thick. Two sheets of corrosion-resistant steel are locked together around a rigid core to give a steel armour thickness of 2.4mm. The door blade is reinforced with an astragal that should prevent anyone jemmying open your door. Between the two sheets of steel that form the exteriors of your door, there are integral steel stiffeners and mineral wool that provide additional strength and insulation. 


The Door Frame


A door is only as strong as its frame. Everything described above would be useless if screwed into a weak timber frame. Our Metal Security Doors are installed along with a fully welded steel frame and anti-jemmy sub frame. The door and frame are attached by stainless steel hinges and security dog bolts.

  • Transom windows
