Coresteel Buildings is Revolutionising Steel Building Construction

We are a commercial building construction company in New Zealand, with over 10 years’ experience in the steel building industry. With our unique design technology and expert design engineers, we create cost-effective steel buildings of any size and shape – without compromising structural integrity.

Our Construction Methods

At Coresteel, our unique construction method has made us a leader in the commercial and industrial steel building industry.

Designed to be long-lasting and spacious, our building solutions are engineered to the highest standards of strength and durability. We can adapt our systems – the patented Bracketless Portal System or the Tapered Box Beam – to create a custom design to meet your exact specifications. We cater for everything, from expansive industrial and commercial buildings for your large-scale retail premises or storage facility, to spacious commercial aircraft hangars, steel frame homes and American-style barns.

Following design and engineering, Coresteel will work with you to manage consents through to full construction.
