Specialists in Maintenance, Fabrication, Machine Shop and Certified Pipe Welding

Providing expert maintenance services to multiple industries has been a key part of our business since 1972. It can be a complex and risky job, and we stand by our commitment to deliver services safely, to the right standard, on budget and on time.

We routinely help customers with:

  • planned 24/7 shutdowns
  • preventative plant maintenance
  • emergency break downs and call outs

Our Nelson facilities are a great base from which to service both local and nationwide customers. With years of experience providing specialist maintenance services to nationwide customers, often in remote and hostile locations, we’ve had ample opportunity to refine our skills in mobilising people and plant. For an idea of what we can do check out some of our projects.

Our multi-skilled fabrication team provides a range of steel services to diverse industries.

Projects large and small have been completed from our dedicated fabrication workshop in Nelson. We also have experience working at customer sites nationwide.

Just some examples of our specialist fabrication work are shared below:

  • Fabrication of structural elements for buildings, seismic upgrades and industrial plant.
  • Fabrication projects including the supply and install of structural steel for the new Nelson Airport terminal.
  • Fabrication projects on The Buffalo, Holcim’s cement carrier.
  • Fabrication and installation of thermal oil pipes and pipe bridges and other processing equipment for the timber industry.

When you engage our project managers you will also have access to our inhouse designers and estimators, so your project will be in the safest of hands from start to finish. The availability of our other skilled teams including fitters, machinists and certified pipe welders also creates opportunity for bundled solutions when required.
