Constructed of high-quality steel, a security door provides extra protection for homes and businesses against break-ins to the front or rear of the property.
Unlike ordinary front doors made from materials such as timber, uPVC or composite, a steel security door cannot be forced open with basic tools, preventing burglars from quickly gaining entry to the property.
Steel security doors can be used in a range of commercial environments including shops, garages, warehouses, jewellers, offices, pharmaceutical companies and more. They can also provide extra security for residential premises.
