Whether you’re after the full turn-key service, a steel structure or a shell to fit out yourself, Coresteel can help.

No matter our involvement, you can be assured we can offer the most comprehensive solution in the marketplace.



Take the time to sit down with others to create a list of everything your ideal building would include. Each and every Coresteel Building is custom-designed to the owners’ exact specifications. Check out the buildings we’ve done before for ideas. Knowing your site location is a huge advantage, as this has implications on the design and engineering style and costs.



Take the first step – give us a call, send an email, fill in our website enquiry form or send us a message on Facebook. With franchise locations from the Kaitaia to Invercargill, we have New Zealand covered.



Coresteel’s online system – Constructor – allows us to quote pre-engineered and bespoke buildings in real-time. When your design is confirmed, Coresteel’s in house team of architectural draughtspeople will detail your project. We can also work with you and your designer, draughtsperson or architect to ensure a smooth process.



All Coresteel buildings are fully engineered to the highest standards by our team of in-house engineers. A signed producer statement (PS1) will accompany architectural plans for council lodgement.



Coresteel’s parent company Donovan Group, custom-manufacture all cold formed steel sections and the larger Tapered Box Beam sections in their Whangarei plant. Each structure is combined with fasteners, wall cladding and roof cladding, before being dispatched, thus reducing costs and improving efficiencies for you.



The construction of your building will be managed by your fully-trained local franchise operator.  Customers are often surprised by the construction speed of our buildings, which is made possible by our patented Bracketless Portal, Tapered Box Beam systems and our experienced construction teams.



When the work is done and you’re completely happy with the finished product, the handover is complete.
