Why put your employees in front of anything else?

Everyone deserves to return home safe.

Mayfield Industries is committed to designing and manufacturing products that provide a safe operating environment for our clients, who we recognise are reliant on critical electrical infrastructure to deliver their promises.

Transportable Switchrooms

Designed and Engineered for the sole purpose of creating a protective environment for the sensitive switchgear throughout the life cycle.  The structural design is key to ensuring rigidity, but offers flexibility to optimise a custom solution for our Clients.
