The Heavy Metal Company Limited

The Heavy Metal Company Limited has been casting and engineering metal in Wellington since 1999, undertaking creative projects of all sizes for the New Zealand art and design industries. Heavy Metal incorporates a traditional metal casting foundry and workshop, artist gallery and precision grinding and sharpening service under one roof.

Founded in 1999 by Master Foundryman and Sculptor Brett Rangitaawa, and Product Designer Jen Waterson, Heavy Metal has established itself as one of New Zealand's leading metal workshops, specialising in large and complex casting, metal conservation, restoration and repair.

Our onsite gallery The Foundry Gallery  showcases metal art and object designed and crafted at Heavy Metal; and offers a selection of Maoriana, vintage, retro and industrial collectables, jewellery and curiosity.
