Metal Expertise

Rooted in nearly a century of practice, our expertise in metals stretches from in-depth knowledge of different metals and their properties, to the mastery of techniques to recycle, smelt, and mold them. This allows us to create high-quality ingots and deliver excellent metal recycling and demolition services.

International Standards

From our humble beginnings in New Zealand to our significant presence across Australasia and the global stage, we've accumulated a wealth of experience dealing with diverse markets and challenges. This international exposure strengthens our ability to serve clients worldwide, respecting regional specificities and standards.

Zero Waste Policy

Our commitment to the environment is unwavering. Our goal is not just to recycle, but to learn more about how we can contribute to a sustainable future where zero waste is the norm.

Smelting Quality Control

Our consistent, high-quality production standards stem from nearly a century of refined quality control processes. In our IANZ and ISO-17025 accredited laboratory, certified metallurgists utilise advanced instruments to test throughout the production process. You receive metal that meets your exact specifications, ensuring confidence in what you are purchasing and using in your project.

Art Casting Alloys

Art Casting Alloys

The design of the artwork or the intended installation environment can often present challenges. Hayes Metals has the experience and expertise to collaborate with the artist or foundry to recommend the most suitable alloy or custom-tailor an alloy to meet the needs of all stakeholders, including the artist, foundry, and artwork owner.

Substation Decommissioning

Substation Decommissioning

Some of the equipment was situated in hard-to-reach areas, making a straightforward lift impractical. We employed our specialised equipment to construct rail tracks, enabling us to safely move the equipment from their locations to an area where we could then lift them using one of our crane trucks.

Scrap Metal

Scrap Metal

The project covered various aspects of collection, ranging from the use of simple scrap bins to handling large items that required individual loading with our crane-equipped trucks, through to the decommissioning and removal of transformers using our specialist equipment, which enabled complete disassembly and recycling within a fully bunded containment area.
