“Thank you once again for the delivery of the panel on time and in full working order. We have the panel mounted and wired up and we were able to complete our in house factory acceptance test today in preparation for a visit by RioTinto tomorrow. In fact, this was one of our best FATs in a while, with everything functioning exactly as it should.

I can assure you that the word amongst our engineers is “we have complete confidence in Metroid, and know that when they deliver a panel it will work first time, every time”.

It has been a pleasure to work with you on this project and you were able to rise to the challenge of a tight delivery schedule and technical complexity…and in the end you made it look easy.”

- Ivan, Project Manager

“Love the excellent quality products and the fast response to quote requests.”

- Luke, Sales Engineer

“Metroid provide an excellent service for all of our electrical engineering needs. Our industry demands innovation which Metroid are always providing on each new project.

The entire team make a project easy from the initial tender through to the design and commissioning process. We look forward to many more successful projects in the future!”

- Steve, Project Manager

“Leadtimes are very competitive.”

- Jason, Project Manager

“Just a quick note of thanks to the Metroid team for your fast and accurate technical help with the controls for this ultrafiltration package.

Emails were responded to within the hour and client queries addressed very professionally. This assistance and level of support for critical plant such as controls for this Ultrafiltration package is much valued and gives us the needed confidence for future repeat business.

Rod is an excellent commissioning engineer and his “hands-on” expertise on site was much appreciated – we will definitely use Metroid again!”

- Drew, Project Manager

“Please pass on our thanks to Martin and your estimating team for your timely technical quotations received recently.

The short turn-around time has really helped us get our packaged treatment plant proposal into client well before deadline. Waiting for supplier quotes is one of our biggest delays in getting quotes to clients on time and Metroid’s speedy service is much appreciated – whilst fast we noticed you covered all the detail very thoroughly as well – good job keep it up!”

- Matt, Project Manager

“It is awesome to have Rod assisting with our projects. He is an excellent operator.”

- Brendan, Engineer

“We always get fast response, and good communication on all stages of a project. Everyone is very knowledgeable.”

We’ve had nothing but good service from Metroid and it doesn’t go unnoticed.”

- Cobey, Contracts Manager

“Metroid’s people have definitely left a good impression on this first job with professionalism and pleasant natured people to deal with.

Please pass this feedback onto the others and let them know the effort to dispatch prior to the Christmas break is much appreciated. We look forward to working with you on future projects and wish you all a safe and happy Christmas.”

- Chris, Project Engineer

“Quick turnaround on switchboard pricing, drawing design/changes and fabrication of panels.”

- Michael, Project Manager

“Congratulations to the team at Metroid. We really appreciate you working towards achieving a tight delivery time frame, whilst still being able to respond to the complex specifications.

Looking forward to receiving the panel next week, and having your professional staff commission it with us.”
