Frequently Asked Questions.
Do you offer welding for heavy machinery in New Zealand?
Yes, we provide certified welding services including MIG, TIG and arc welding for structural and mechanical applications.
Can you repair a cracked excavator bucket or boom?
Absolutely. We specialise in welding, re-plating and reinforcing cracked or worn buckets, booms, arms and more.
What is line boring and when is it needed?
Line boring restores worn pivot points, bores and pin holes to OEM spec. It’s typically needed when components show excessive play or wear.
Do you fabricate custom attachments or machine mods?
Yes. We build custom guards, mounts, access steps, toolboxes, and structural mods to suit specific machines or work environments.
Can I get hardfacing done to reduce bucket wear?
Yes. We apply wear-resistant overlays to high-impact or high-wear areas, extending component lifespan significantly.
Do you offer mobile engineering or field welding?
We offer limited mobile welding and line boring services, depending on region and scope. Enquire with your local branch.
What brands or machines do you repair?
We support most major OEMs including CASE, Metso, ASV, McCloskey, and legacy brands like Kobelco and Moxy.
Can you rebuild damaged trailers or truck decks?
Yes. We repair or fabricate structural components for transport gear, including ramps, brackets and tie-down systems.
