Ordinary wooden doors offer little resistance to a determined attack and, when used on a block of flats, can actually attract the attention of undesirables. The consequence is frequently a complete lack of security, vandalised halls and staircases and a marked increase in burglaries.

Steel doors represent a totally different proposition and provide serious problems for vandals. Available with security fixings for closers, proximity readers and magnetic locks, they provide over a metric tonne of holding force.

A ‘Fireman’s Switch’ complies with fire regulations and the doors themselves are available in a choice of colours and designs. Each installation is tailor made to the property.

Delta Security are proud of their pioneering achievements in the design and technology of these doors, which are installed to numerous properties throughout London.
