Similarities and differences of armored and steel doors
In order to hide the cracks between the frame and the door, metal cashes are welded when installing the armored door.
Unlike a steel door, armored has a large weight, so the most reliable loops are used when installing. Castles must also have a high degree of protection. Insulation and sound insulation of the armored door is made of the same materials as for a steel door.
The cost of an armored door is much higher than ordinary steel, but it will be able to protect you in any situation.
