Kula Beach Homes | Contrast Constructions | Sunshine Coast

Building with structural steel within 200 metres of the surf means salt air corrosion is the first problem to solve, not the last. On the Kula Beach Homes estate at Mount Coolum on the Sunshine Coast, Network Steel supplied hundreds of interconnecting, hot dip galvanised steel members for a boutique estate of architecturally designed homes, built by Contrast Constructions Pty Ltd. 

How do you protect structural steel from salt air on a coastal build?

You keep the galvanised coating intact. Hot dip galvanising is what stands between coastal steel and corrosion, and site welding burns straight through it. With the Pacific Ocean only 200 metres from the Kula Beach site, protecting that coating was non-negotiable. Network Steel detailed and fabricated every connection off site, so the steel arrived galvanised, complete, and ready to bolt together. 

How do you achieve large clear spans for open-plan living?

The Kula Beach homes were designed around open-plan living, which put a lot of structural demand on the steel. Large clear spans need steel members that carry the load without intermediate supports getting in the way of the space. With four architectural practices engaged across the estate and every home individual in design, each steel member was designed on its own terms. 

Why does 3D steel detailing matter on a project like this?

Because it takes the risk out before the steel is cut. Network Steel had an established working relationship with Contrast Constructions, and used 3D modelling to detail the steel framing for each individual residence. That gave the Contrast team the chance to review the model and make changes so other trades could connect to the steel cleanly, before anything was fabricated. Hundreds of interconnecting members were produced this way and went together on site without a hitch. On a build with this much bespoke steel, the detailing is what turns a complex job into a straightforward one.

FAQ

Does structural steel need special protection near the coast?
Yes. Salt air accelerates corrosion, so steel used close to the ocean needs a durable protective coating. Hot dip galvanising is the standard approach for coastal residential steel. On the Kula Beach estate, 200 metres from the Pacific, every member was hot dip galvanised.

Why avoid site welding on galvanised steel?
Welding burns off the galvanised coating at the join, which creates a corrosion point that is difficult to repair to the same standard. Detailing and fabricating connections off site keeps the coating intact and is the safer approach for coastal builds.

Can you build large open-plan spaces with structural steel?
Yes. Structural steel carries large clear spans, which is what lets you open up living areas without intermediate columns or load-bearing walls interrupting the space. Every Kula Beach home was framed for open-plan living.

Does Network Steel supply structural steel on the Sunshine Coast?
Yes. Network Steel services the Sunshine Coast, including coastal and hinterland builds. For more details on our Kunda Park location, please click here.
