No matter where you are in New Zealand, there’s a local Coresteel franchise that can help to get your building project off the ground.

We pride ourselves on working with you throughout the entire process, from the first contact with your local franchise operator, through to design and engineering, manufacture and construction.

Throughout the process, Coresteel’s Constructor software provides a direct link between Coresteel’s designers/engineers and your local franchise, which means that they can follow the progress of the project online and inform you when milestones are reached along the way.

By getting involved with your project early and overseeing the entire building process, we head off as many potential delays to eliminate cost overruns.
