M&J was founded in 1990 by Mike, Jasmin and Chris Garland and first began installing and repairing conveyor belts from their first site in Cwm, Ebbw Vale.

​

As the company grew, it expanded into the manufacturing of new conveyors and general engineering, moving twice to new locations. 

​

In 1999, M&J made it's third move to Tafarnaubach Industrial Estate, where it settled, and still remains today.
