Consultancy

Team of experts.

We work with you to understand your site, goals and performance needs — including early input into concept design and structural considerations.

Design

Start right. Finish better.

Set the foundation for your project’s success early. We listen to you to define the scope and develop a tailored design that optimises buildability, subtrade integration, structural performance, and identifies opportunities for cost savings and efficiencies at every stage, which we demonstrate with your fixed price.

Fabrication

Precision steelwork. Built to perform.

Drawings, fabrication and painting are carried out in-house at our purpose-built production facility. This ensures full control and compliance and enables us to meet and often exceed expectations on quality, cost, and turnaround.

Installation

Seamless delivery. Safe, efficient installation.

The precision and care we take in production extends to the way we work on site. Our highly experienced install team stand it up fast — collaborating with other trades to minimise downtime and deliver your structure to spec, safely and without delays.

What you can expect when you work with HML

Best Value

High-performance structures without the hefty price tag. Smarter design, a fixed-price upfront and an efficient install all add up to better value.

A CUSTOM SOLUTION

No two projects are the same —so we don’t do one-size-fits-all. We don’t cut, paste and tweak from a shortlist of templates, we design for your needs, your site and your budget.

SMARTER DESIGN

We bring the practical, engineering know-how needed to design solutions that minimise cost and risk — and maximise results.

A STRONG STRUCTURE

We build structures that are robust, compliant and engineered for strength, structural integrity, and meet wind, seismic and fire regulations.

TESTIMONIALS

From our clients

I was recently on site at The Junction in Nelson, and the team were full of praise for HML’s work there to date. I normally get the complaints, but was refreshing to see the opposite!

Scott Watson

Director

We have done a good number of projects in the Wellington region with HML Engineering, and their service is great, the Project Management team has good communication which is backed with an efficient install team that works to a high-quality standard. The quality of the steel fabricated is obvious with the speed and accuracy of the install.
