Preliminary, IFA or IFC? Understanding Structural Steel Drawings

Preliminary. IFA. IFC.They might look like small notes on a set of structural steel drawings, but they tell you something pretty important: where those drawings are in the process – and whether they're ready to build from.At Alted Engineering, our structural steel drawings move through defined stages before fabrication and construction. Understanding which version you're looking at helps make sure everyone – builder, architect, engineer and fabricator – is working from the right informatio...

Why Structural Steel Installation Is Quoted as an Estimate

When we quote structural steel for a project, you'll often see the fabrication priced separately from the installation.There's a reason for that.We can accurately price the steel components we're fabricating in our workshop. We know what's on the drawings, what materials are required and what's involved in making them.Installation is different.There are simply more variables once we get to site. That's why at Alted Engineering, structural steel installation is generally provided as an estimate r...

Opening Up a Waihi Beach Home with Structural Steel

Creating open-plan living often starts with removing walls. But before anything comes out, you need to make sure the structure above has somewhere else to go.That's exactly what this recent renovation at Waihi Beach involved.Working alongside Hamish and the team at Nextgen Construction, our team was brought in to design, fabricate and install the structural steel required to transform the ground floor of this home into one large, open living space. The finished result feels effortless, but ...

Corten Screening and a Family Crest on a Hilltop Home

For a coastal-based engineering business, not every steel job is structural. Some are there to be looked at.This one sits on a hill at Te Rerenga, north of Whitianga. The brief was clear enough: screening that did a job, without looking like something bolted on afterwards. It had to sit with the house and the landscape around it. Corten steel was the answer....

Structural Steel for a Large Architectural Home in Morrinsville

It's a 460sqm architectural home near Morrinsville, built by Jeremy Eulink from Bareacre Builders. He found us online and rang around for quotes. He wasn't after a supplier to chase up. He wanted an engineering company to partner with going forward, and what he backed was the way we work....

A Pauanui Handrail and Why Access Matters on the Coromandel

Not every install comes with fresh blueberry muffins. This one in Pauanui did.An elderly couple needed a safe way down their front steps. Bennet met them on site, talked through what they needed, and designed a custom 316 stainless handrail to suit the deck and the height that worked for them. Their family lives out of town and were stoked to know mum and dad could safely navigate their own stairs.It's a small project on the surface. But it sits inside a bigger story about how people live on the...

What Is a Cantilever Gate? And Why Rural Waikato Properties Are Using Them

Most sliding gates work fine - until they don’t.If you’ve got a sealed, flat driveway, a ground track will do the job. But the minute you’re dealing with gravel, camber, or a bit of ground movement, things start to go wrong.Tracks fill with debris. Gates start dragging. Rollers wear out faster than they should.That’s usually the point people start looking at cantilever gates....

Structural Steel for a Hillside Build

Not every project starts with an easy site.Set above Tairua on the slopes of Paku, this build presented a combination of tight access, elevation, and coastal exposure - the kind of conditions where planning and precision matter from the outset.For this project, our team at Alted Engineering was engaged to deliver the structural steel package, working alongside Taylor Projects and Solutions on a new build that required both accuracy in fabrication and discipline on site.From fabrication through t...

Why Your Steel Project Timeline Starts at Deposit (Not “Let’s Go”)

One of the most common conversations we have is around timing.A client is ready to move forward, the project’s been discussed, and the question comes: “How soon can you start?”The honest answer?Your project timeline doesn’t start when you say “let’s go”.It starts when your deposit is paid.And there’s a good reason for that.Step One: Securing Your Place in the ScheduleWe’re often working across multiple projects at once, such as residential builds, council work, custom fabr...

Getting Structural Steel Right Before It Reaches Site

Before steel ever reaches site, the outcome is already decided.For this Coromandel build with Taylor Projects and Solutions, our focus was on fabricating the structural steel components that would later be installed on a challenging hillside site in Paku.While the location brings complexity, it’s the work done in the workshop that determines how smoothly installation runs....

Corten Steel vs Mild Steel: What Actually Lasts Outdoors?

Most people think rust is just rust. It’s not.Two pieces of steel can look almost identical – that same weathered, burnt-orange finish – but behave completely differently over time.And when you’re building anything outdoors, that difference matters....

Council Fencing & Coastal Steelwork for Thames Coromandel

When you’re building for public spaces, “good enough” doesn’t cut it. Every weld, every bolt, every detail needs to be right the first time. Why? Because the community relies on it.

Smart Fencing in Tairua

There’s a fine line between keeping a property secure and keeping the view intact — especially when the brief includes aesthetics, Thames Coromandel District Council compliance, and coastal conditions.That was the challenge for our latest fence and gate install in Tairua. Bennet Gage-Brown and the Alted Engineering crew delivered a custom galvanised steel solution that balanced durability, discretion, and design.What the Client Needed:✅ Keep fence height around 1m to preserve harbour and b...

Building Skills, Certifying Quality, and Backing Our Team

When you care about quality, you don’t cut corners — you certify them. And when you see potential in your crew, you back it.Over the last couple weeks, we've been deep in both: weld test certifications on one side of the workshop, and the launch of Cooper’s Heavy Fabrication apprenticeship on the other. Two very different moments, but both tied to the same idea — doing the job properly, and building a team that takes pride in getting it right.That’s why March was a big month behind the...

The Power of Good Drawings: How In-House Design Sets Alted Apart

At Alted Engineering, steel is only part of the story. Before any steel portal is lifted into place or a ridge beam is bolted down, there’s a crucial phase that shapes everything to come: the drawings.Two recent residential builds—one perched high above the coastline at Paku, the other nestled into a quiet street in Pāuanui—show just how important that design phase is. Both required smart structural steel solutions. Both had site-specific challenges. And both were made easier thanks to ha...
