A high-rise apartment building wished to offer residents the highest possible security. Double steel security doors were installed in every unit. One day whilst out & about, an elderly tenant had an accident and was taken to the hospital. Neighbours became worried when they noticed his untouched newspaper outside his apartment the following day and called the police to break in to see if the elderly gentleman was in trouble.
UPVC Doors: The UPVC doors are made up of materials like plywood, polystyrene or plastic. These doors are now redeveloped using steel so as to improve security and rigidity. The UPVC doors are suitable for houses but are having a lot of drawbacks attached to it.
Disadvantages: The aluminium doors are not oxidation resistant thus; oxidation appears in them in the either form of residue or pitting. The risk of being corroded always exists with aluminium doors, if certain precautions are not taken from time to time.
