Case Studies

We are a true recycler of materials, rather than a simple ‘trader’ of materials like all other scrap metal ‘recyclers’ in New Zealand.

How can we apply our expertise in large-scale demolition projects, innovative metal recovery and recycling to your project?

Hayes Metals consistently demonstrates our expertise and innovative capabilities through successful projects that we undertake for our clients. Below are several case studies that showcase our commitment to excellence.

These case studies highlight Hayes Metals' ability to tackle complex challenges and deliver cutting-edge solutions that propel industry advancements. Our unwavering dedication to quality, sustainability, and customer satisfaction is evident in every project we undertake.

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.

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.

Decommissioning

The project involved the decommissioning and removal of transmission towers in some very difficult locations, which required extensive planning and precise execution to ensure that neighbouring properties and buildings were not damaged.

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.

E-Waste (Electronic Waste)

This project had many sites throughout the country, so the logistics, timing and planning were key in having the correct people and equipment onsite in a carefully sequenced order to enable the swift and seamless removal of the equipment that could then be fully recycled back at the Hayes Metals base.

Subsea Structures

The project required complex cutting plans to ensure that the sections were cut safely within a containment bund, such that they were optimised for loading onto our trucks and subsequent recycling.
