At Coresteel, we specialise in the design, manufacture, and construction of steel hangars

Our steel hangars are the first choice for a diverse range of aviation clients. Using our innovative portal systems, we can design and build steel frame hangars of virtually any size without compromising structural integrity.

We’ve built airplane hangars all across New Zealand and are always looking for new projects to work on. Get in touch with our expert team to discuss your steel hangar construction needs.

One-stop shop

Coresteel’s one-stop-shop approach to steel hangar construction means we can manage the entire building process for you. From design, engineering, and manufacturing to full hangar construction, our skilled franchisees will deliver a seamless building experience.

Lasting protection

Nothing beats knowing your investment will be protected against the elements. We bring in-depth expertise to ensure every plane hangar we build is designed to withstand high winds and seismic loads. Plus, every Coresteel hangar is built with hardwearing steel sourced from New Zealand.

Large spans

By combining the benefits of our larger structural steel sections with our experience in design, you can achieve clear spans of up to 75m. Whether you’re in need of a modest-sized helicopter hangar or multiple bays for a commercial fleet, our structural systems grant you design flexibility.

Client testimonial

“Coresteel Buildings meant we could realise the vision of a hangar that was both practical and stylish in its design. The interface with our architect was hassle-free and once the building got to the structural design stage it was great to have an engineering team as part of the Coresteel package.”
