Doors made from fiberglass provide an extra layer of security from intruders. The double or triple pane, glass will not shatter should an intruder attempt to break it. They also have a minimum 12 inch (30.48 cm) lock block that adds more strength, should a burglar attempt forced entry.
These doors require separate welding equipment.
Steel security doors with the vision panel are known for the better visibility if Obscure glass used in the security doors is of the high quality. So when any stranger came to your house, you can easily view him though the glass panel used in the security door. People are always worried that if the intruder can break the glass and enter the premises but steel doors are having the small glass panel so that intruder is not able to enter the house and if you are available at that time you can easily and clearly view him.
Disadvantages: The aluminium doors are not oxidation resistant thus; oxidation appears in them in the either form of residue or pitting.
Plus, although \"fire doors\" can be purchased, businesses still receive excellent protection against the spread of fire with steel security doors. Steel doors also provide increased energy efficiency, since they insulate the cold air from outside up to 4 times better than wooden doors.
