Something a bit different, but definitely needed!

This container had been shortened in a previous life, with small stitch welds and silicone used to seal it back up. Trouble was, it hadn’t kept the moisture out and rust had set in.

We were asked to sort it properly.

First up, pulling out all the old silicone and prepping everything for welding. We then added a new bottom rail, fully welded the exterior, and coated the raw steel with a two-pot zinc-rich epoxy before the top coat went on.

Should be good for another generation now. 💪

Pretty cool seeing not one, but two Alted jobs taking out Gold at the Master Builders House of the Year Awards. 👏

Both of these Whitianga homes featured plenty of Alted work behind the scenes - from structural steel through to a range of the external finishing details.

A huge congratulations to and .ltd on the Golds. Great homes, great result, and pretty satisfying for our team to see our work sitting behind both of them.

Nice one, team. 💪

Stone walls. Cast-in hinges. Five custom aluminium fin gates. Automation. Sensors.

About to kick off in Whitianga at The Moorings. Lots of planning going into this one!

Twenty years old doesn't mean you stop improving it.

This Ducati Monster S2R rolled into the workshop looking for a modern update, without losing the character that makes it a Monster.

Every part started with a problem to solve.

The factory lighting made way for slimline LED components throughout, including a new halo headlight, discreet bullet indicators, an integrated stop/tail light and LED number plate light.

Then came the custom fabrication.

From cardboard templates and scissors through to SOLIDWORKS, laser cutting and powder coating, we designed and built:

• Custom headlight brackets to mount the new LED headlight and indicators
• Rear brake and chain guards with a clean laser-cut finish
• A new tail light mount integrated into the tail tidy
• An instrument cluster panel with a dedicated daytime running light switch
• Modified Renthal Fat Bar mounts to suit the new high-rise bars and lock-on grips

Nothing off the shelf. Every bracket designed, fabricated, finished and installed in-house.

Sometimes the best engineering isn't about making something new.

It's about making something you already love even better.

Opening up the ground floor of this Waihi Beach renovation was a little more involved than simply removing a few walls.

To create one large, open living space, we installed two structural steel beams, supported by new timber framing and foundations.

The sequencing was the real challenge. Existing walls had to be carefully propped to support the upstairs structure while foundations were dug around the existing footings, reinforcing steel tied in, and the new beams lifted and hoisted into place.

With detailed site measurements and careful prefabrication, everything fitted exactly as planned - making the install as smooth as possible once the steel arrived on site.

A great project to be involved in alongside Hamish Bain and the team at . Thanks for having us on board.

The finishing touches can take just as much planning as the big bits at the start.

We've been involved in this Tairua new build from day one. Structural steel early in the project, and now back again helping finish things off with the final details.

So, what did we do?
- Aluminium handrails
- Powder coated to match the joinery
- Stainless steel support brackets for the timber screening

Simple, clean, and in keeping with the style of the rest of the house.

Big shout out to on this one. You've built an awesome place mate!

Great to have been involved from start to finish.

Kids in, dogs in, we're winning 🙌

The new owners of this St Andrews home in Hamilton needed a gate installed quickly. With a narrow gap between the house and boundary wall, the priority was simple - keep the kids and dogs where they're meant to be. And yes, a bit of privacy and security too.

Fabricated in Tairua, the team hit the road to install a custom aluminium gate built to suit the space exactly, featuring:
- Vertical slats for privacy
- Powder coating matched to the home's joinery
- Stainless hinges fixed directly to the block wall
- A support wheel to make it easy for everyone to open and close

Strong, tidy, and built to last. Just the way we like it. 💪

Big openings. Six-metre chimneys. 450sqm+ of architectural ambition 👌

This Morrinsville build with Bare Acre Builders Ltd has been a great one to be part of.

Our scope included structural steel for large-span garage openings, steel through the main living areas, and framing for one of the two six-metre-high chimneys.

And a shoutout to LAD Architecture! Bennet reckons some of the clearest drawings he’s worked from... When details are sorted upfront, fabrication and install become a whole lot smoother.

Good people. Good planning. Good outcome.

Keen to keep doing more work like this across the Waikato 💪

Not every steel project is structural. Some are more of a statement piece!

For this hilltop home, the brief was clear: create functional screening that looked like it belonged with the property and surrounding architecture.

The client asked us to design and fabricate custom Corten steel panels in two locations:
- Garage screening panels
- A custom enclosure to conceal bins, gas bottles and utilities behind the sleepout - complete with a large sliding access door

To make it personal, we also incorporated the family crest into the design, converting the artwork into a laser-cutting file for the Corten steel.

Everything was modelled upfront, including hidden fixing locations and post placement, to ensure a clean finish once installed.

Big shout out to Dan and the team at Urban Homes whose crew helped make the final fitment seamless.

Not every install comes with fresh blueberry muffins 🧁 This one in Pauanui did!

An elderly couple needed a safe way down their front steps. met them on site, talked through what they needed, and designed a custom handrail to suit the deck and the height that worked for them. Hose holder welded straight onto the rail too, so the garden hose has a proper home.

One small surprise on install. When Bennet pulled up the decking planks to secure the rail, the brace beams weren't where he'd expected. No drama. Off to the store, back with what he needed, job sorted.

316 stainless steel. CNC mandrel bent tube. Built for coastal conditions, built to hold real weight.

The family lives out of town and were stoked to have peace of mind that mum and dad can safely navigate their own stairs.

Hopefully word gets around the Pauanui club 😎 We can do plenty more of these!
