If you’re unsure of any of the terminology used below, refer to our glossary. You’ll be talking like a pro in no time!



Do your homework and create a wish list! Check out the buildings we’ve done before and make a list of the features your ideal building would include. It’s also handy to know your site location, 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.



Each and every Coresteel Building is custom-designed to the owners’ exact specifications. But that doesn’t mean you’ll be left waiting for a quote! Coresteel’s online system – Constructor – allows us to quote pre-engineered and bespoke buildings in real-time. When your design is confirmed, our in-house team of architectural draughtspeople will detail your project. If you have your own designer, draughtsperson or architect, we can work closely with them 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 be provided with your architectural plans, to be lodged with your local council.



Coresteel structures are proudly made from steel directly sourced from NZ Steel in Glenbrook and are manufactured by our parent company Donovan Group in Whangarei. Each structure is combined with fasteners, wall cladding and roof cladding, before being dispatched direct to your building site. This reduces costs and improves efficiencies for you.



The construction of your building will be managed by your fully-trained local franchise operator.  The speed at which our buildings ‘go up’ surprise many of our customers. Within a few days the entire frame can be erected. This is made possible by our patented Bracketless Portal System, Tapered Box Beam systems and our experienced construction teams.



When the work is done, you’ll be invited to complete a full walk through of your building. When you’re completely happy with the finished product, the keys are yours and the handover is complete!
