Information about our Security Doors

Steel Security Doors

Our steel security doors are made to the highest quality guidelines and incorporate a multi-point locking system which locks 12 points around the steel frame. Like all of our products our steel security doors come CE marked which is a legal requirement for any type of door sold in the UK/Europe.

Our single doors are available in either a standard or heavy duty version. The main difference between the 2 is the thickness of steel which is used on the door blade and steel frame (technical specification is shown on each products page) our steel security doors are also available in a double locking version and these are manufactured to the heavy duty specification.

A Steel Shield

Our steel security doors and steel door products offer the highest protection against security threats to your property.

Serving industrial, domestic and commercial needs, we offer unparalleled service and product knowledge, all at competitive prices.

Our steel security doors include a multi-point locking system as standard. This locks into the top of the frame and all around the side of the frame with 2 anti jemmy studs on the hinge side of the door for extra protection. If you look on our accessories page we can also offer upgraded security accessories such as our digital locks and upgraded security cylinders.

Peace of Mind

Manufacture & Installation

Every aspect of our steel security doors’ design, manufacture and installation guarantees that you are obtaining the very best security for your commercial or domestic premises. This offers a peace of mind that is hard to find with other types of steel doors and should be a priority to most business owners who are looking to buy a reliable steel security door at the best possible price.

Although steel fire doors can be purchased, businesses will still receive excellent protection against the spread of fire with our steel security doors. Please speak to one of our experienced sales staff with any questions that you may have regarding any of our steel security doors.
