We’re proud to receive so many positive testimonials from our customers for our engineering services

Sigma 6 workshops have offered a great service to Stone from planning through to completion of both fitting and fabrication work, they show a great professional attitude and are willing to assist in any task through all hours of the day.

The management act in an extremely professional manner and are very accommodating when faced with any challenges thrown their way, they have assisted in some great site tasks where we have struggled to get the man power to work out of hours and have also shown a great deal of after care following any issues with completed tasks.

The team have recently added a site team which have already proved again the credibility of the company with assistance on an extremely challenging task on our Primary Crusher Breaker, working after 10pm on a Friday to complete the task and cause minimum disruption to our production.
