Structural steel
Strong foundations for award-winning builds.
From coastal show homes in the Whitianga Waterways to large-scale architectural projects in Pauanui, our structural steel delivers strength, precision, and finish that stand the test of time. Every beam, brace, and connection is engineered in SOLIDWORKS, fabricated in our Tairua workshop, and installed on-site by our certified team.
Whether we’re supplying steel for a Master Builders House of the Year winner, reinforcing a complex architectural design, or a standard steel beam to allow for expansive ocean views, our focus never changes. Practical solutions, flawless fit, and steelwork that performs as beautifully as it looks.
