Our team consists of approximately 100 skilled and dedicated staff. We strive to ensure all fabricators hold their AS/NZS 2980 Welding ticket. Our erection crews have their own mobile workshop, containing all the basics for erecting most structures. We also have specialist equipment, such as portable welding plants, various scissor lifts, cherry pickers and cranes, including both a 30 & 20 Tonne Mobile Crane to assist with erecting steel.

Stevensons Structural Engineers was founded in Tokomaru in 1897 by R. J. Stevenson. Since this time, we have developed a proven reputation as leaders in the supply, detailed shop drawings, fabrication, surface treatment and erection of structural steel. Our projects have taken us all around the world, completing contracts in Venezuela, Guam, Nauru (central pacific), Australia, and of course all throughout New Zealand.

We have workshops based in Palmerston North and Wellington, but our head-office and main manufacturing facility is located at Tokomaru, 20Km South of Palmerston North. This is where the basis of steel fabrication and surface treatment is done, and is conveniently located to supply national and international destinations.

Our Tokomaru workshop encompasses our surface treatment facility, where we are able to clean steel using grit blasting to all recognized standards. This is carried-out in our 19.7m × 4.5 m high × 5m wide grit blasting booth equipped with Burwell blasting gear. From here, we are able to apply a multitude of different protective coatings to suit all requirements, including zinc-arc spraying as an industry recognized substitute for hot-dip galvanizing.

Stevensons are extremely proud of their growth and contribution to the construction industry over the years. We hope that our production capabilities and standards continue to be reflected in the successful completion of many major projects in the years to come.

We take pride in providing the best possible product with the best possible service.
