Rocklite® Transformer Doors & Louver Units

ROCKLITE® Transformer Room Doors and Louver Units are made from 1.6mm mild steel; our doors are secure and durable. These doors & frames can also be made from Galvanised steel for coastal conditions, as per customer requirements.


The doors are fitted with 3 x heavy duty brass hinges per leaf, depending on door size and customer requirements.

Door Finishes:

The doors are painted with a red oxide primer, galvanized doors are cleaned with degreasing solution. We do not manufacture doors in hot-dipped galvanized finishes.


Our Transformer Room Doors are fitted with a Pull Handle, Padlatch and Barrel Bolts on double doors. We can also fit a Quick Release Mechanism onto the doors, as per customer requirements.

We specialise in the protection of buildings from fire by the insulation of structural members, walls and tanks against direct attack from flames by maintaining load-bearing members and tank-shells below the critical point at which failure or weakening is likely to occur.
