Coresteel is Donovan Group’s commercial construction flagship, offering two unique steel frame building systems: the Bracketless Portal System and the Tapered Box Beam. Coresteel’s structures push the limits of traditional design with clear spans up to 75m and over 20 franchise operators based around New Zealand to bring these buildings to life. KiwiSpan brings the design and manufacturing capabilities of Donovan Group to the consumer, with quality steel sheds designed specifically for them. Trenz Create A Home enables residential home builders to utilise the power and efficiencies of Donovan Group’s construction, design, and manufacturing systems. With a nationwide network of experienced franchisees, Trenz empowers the consumer to take back control over the design and cost of their new home.


The Design Station team works with a specialised software and engineering system to engineer and detail both standard pre-engineered and specially designed steel buildings. With 3D modelling and designs detailing construction down to the finest features, Design Station delivers precise instructions for manufacturing and construction. Donovan Group Advanced Manufacturing has long been the driver behind the automation, precision and efficiency of our construction projects. The manufacturing team and plant are a critical element in delivering Donovan Group’s end-to-end experience – from design, through to construction.
