Our History

As co-founders of New Zealand’s steel industry, our family has been in the Steel business since 1952. We’re still 100% family owned and operated. Our name is recognised throughout New Zealand, Australia and the Pacific Islands as an industry leader.

We were the first non-manufacturing company to win the New Zealand Export Award for Outstanding Contribution to New Zealand Trade, and we’ve maintained our reputation for quality, service and innovation. While we’ve changed our trading name from RC Macdonald to Macdonald Steel, our values have stayed the same.

To us, everyone is entitled to the same service, regardless of the size of their job. Contact us and you’ll speak to one of our friendly team. Our personal service and commitment to meeting your needs is one of the reasons many of our customers have been with us for decades.
