Established in 1987 by Graeme & Trisha King, Mainline Sheetmetals now employs an experienced team of 18 people. Collectively, we have a wealth of experience and industry knowledge that can only be gained by time spent in the industry.
Located at 209 Ellis Street in Hamilton, our workshop is a modern, purpose built facility to suit our business.

We strive to provide our customers with excellent service and quality workmanship and guarantee our products are working as they should be when you receive them.
As we are a manufacturing business, we can provide you with products that can be tailored to meet your specific requirements.

We have manufactured fuel storage tanks since 1987. Over the years there have been many changes, with improvements both in quality and design and of course many changes to the legislation surrounding the storage of fuel.
Our tanks are HSNO compliant and the range available will provide you with plenty of options to manage the way you store and use fuel.

Mainline also manufacture a range of products for feeding and housing animals in farm and city environments.
These include dog kennels (3 sizes) and tow bar mounted dog carriers, mobile chookhouses suitable for 6 – 8 chooks, hay racks – tow along and fence mounted, feed troughs and silos. Find out more on the product pages.

The fabrication workshop manufactures air conditioning ducting which is made to order and jobbing work as required by the customer.
The welding workshop has the capability to manufacture from 3mm to 5mm sheet steel.

In June each year we can be found at the NZ National Agricultural Fieldays at Mystery Creek in Hamilton. Our site location is G20 in the dairy exhibition area. During the fieldays, we showcase our products to you which often provides the opportunity to meet many of our customers in person.

Taking care of the environment is another important factor in our workplace. Minimising waste and recycling we view as being good for business and good for the environment. Whether it is reducing electricity usage by turning off lights and machines when not in use to recycling metal, plastics, glass or food waste to our chooks, it all helps.
