Substation Doors

Maxium Doors is the UK’s premium Substation doors supplier, where all our steel doors are made to measure and are manufactured here in the UK.

Quality UK manufactured substation doors

Substation doors are high security doors required to provide security and protection to substations and other external buildings in remote or vulnerable locations.  The exposed nature of many substations, often away from the main building or from sight, means high security, protection and resistance to vandalism are prerequisites.

  • Ideal for vulnerable and exposed external door sets.

Advantages of purpose-designed, substation doors.

Our premium, substation steel doors help you secure, ventilate and protect critical outside areas.  With our expert help and advice, we can provide steel security doors designed to keep external buildings regulated in temperature making them perfect for boiler rooms, outside generators, water stations and many more types of outside facilities.

All our doors keep the most important requirement as a priority – that is, the protection of restricted rooms secure against vandalism and forced entry.

Installing a ventilated steel door to any substation has clear benefits over traditional wooden or PVC doors. In fact, to the naked eye, you wouldn’t even know as our steel doors are cleverly coated to look like traditional doors; aesthetically pleasing whilst protecting your premises and everything in it.
