Specialised Doors

We have developed a range of doors to suit special applications such as pump stations, substations and generator rooms. Our doors are manufactured in Stainless Steel (3CR12, 304 or 316), with absolute quality in mind. The doors all adhere to very stringent corrosion requirements. 

Doors are available in light, medium and heavy duty configurations. Suitable for all transformer door applications, but of the best quality possible. Our light doors are much more secure and long lasting than mild steel transformer doors.

The TDL range of 3CR12 secure doors are quickly becoming the defacto standard for critical infrastructure projects. Configured with a built-in panic bar (emergency exit) function, multiple 20mm lock rods, continuous hinge, optional louvres and very high security lock system.

Also visit our LOUVRE page - we have a range of high security ventilation louvres to compliment the range of doors.

Our latest generation transformer door "TDI" and "TDL" doors has been design registered. This range of doors provides a good balance between cost and performance for demanding applications. The doors are highly customisable to suit different project requirements.

We have a brand new hidden hinge that will bring new levels of vandal protection to transformer doors.
