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.
