Why Modern Builders Are Ditching Traditional Welded Connections (And Why You Should Too)
Published: May 2026 | Reading Time: 8 minutes
If you've been in the construction game for more than a few years, you've probably wrestled with the nightmare scenario: pre-welded SHS columns arrive on site, they're slightly off-level, and suddenly you're looking at delays, costly rework, and frustrated site managers. Sound familiar?
You're not alone. This is the reality for thousands of builders across Australia every single day. But here's the thing—it doesn't have to be this way anymore.
The Problem With Traditional Welded SHS Connections
Let's start with the elephant in the room: traditional welded SHS posts and cleats are rigid, inflexible, and expensive.
When you order a standard welded assembly, here's what actually happens:
Factory Pre-Welding: Cleats and baseplates are permanently welded to your SHS columns in a factory environment. Sounds good, right? Wrong.
Heavy Transport: You're now shipping 4-meter welded assemblies that weigh significantly more than separate components. That's increased transport costs and logistical headaches.
Site Inflexibility: Once those cleats are welded, they're locked in place. If your beam levels need adjusting by even 50mm, you've got a problem. You either make it work awkwardly, or you rework the entire assembly.
Hidden Costs: What looks like a cost-saving factory solution ends up burning cash through delays, rework, and inefficiency on site.
And let's be honest—this approach assumes everything goes perfectly during the design phase. We all know that rarely happens on real construction projects.
Enter: Mechanical SHS Cleat Systems
This is where the construction industry has experienced a genuine innovation. Mechanical cleat systems—specifically designed cleats that slide onto SHS columns and secure mechanically—are fundamentally changing how builders approach structural connections.
Instead of pre-welding everything, you assemble components on site. Think of it like building with LEGO for structural steel. Everything connects precisely, nothing is permanently fixed until it's verified on site, and adjustments take minutes instead of days.
Here's What Actually Changes
Speed: No factory lead times for welded assemblies. Your materials arrive ready to use, and assembly happens at your pace on site.
Accuracy: Remember that 50mm adjustment issue? With mechanical cleats, you can slide the connection up or down the column to match exact beam heights. This level of precision dramatically reduces rework.
Control: The builder—not the factory—controls positioning. You see the structure take shape, verify it's correct, then secure everything. This is genuinely empowering for site teams.
Flexibility: Beam levels change? No problem. Use different fastening methods as needed—tek screws, welding, or bolts. The system adapts to your requirements, not the other way around.
Transport Efficiency: Lighter components mean lower freight costs and easier handling on site. This might sound minor until you've coordinated delivery logistics for a large commercial project.
The Technical Advantage: How Mechanical Cleats Actually Work
Most people assume mechanical connections are less robust than welded ones. This assumption is wrong, and it's based on outdated thinking.
Modern SHS cleats are engineered to channel-specific tolerances. They fit standard SHS sizes (65x65mm through 200x200mm) with precision that ensures even load distribution. Once secured—whether by tek, bolt, or weld—the connection is as solid as any factory-welded assembly.
The genius is in the timing. You don't commit to permanent positioning until you're absolutely certain everything is correct. Once you're satisfied:
Tek & Weld: Combines speed with permanent security
Weld Only: Provides factory-like reliability after on-site verification
Bolt Only: Allows complete reversibility (useful in renovation or modular projects)
You're getting factory-quality results with on-site flexibility. That's not a compromise—that's an upgrade.
Real-World Applications Where This Matters
Verandah and Deck Construction
Verandah projects often sit on sloped or slightly uneven ground. Traditional welded posts mean accepting whatever heights the factory provided. Mechanical cleats? You adjust each post independently to achieve perfectly level beam positions. No shimming, no headaches.
Multi-Story Commercial Builds
In larger commercial projects, floor-to-floor heights sometimes vary slightly due to concrete tolerances or design changes. Having adjustable cleats means each beam level can be positioned precisely, ensuring structural integrity and aesthetic alignment.
House Raising and Renovation
When you're raising older properties or adding new structures to existing buildings, flexibility is everything. Mechanical cleats let you work with the reality of what's there, rather than forcing things to fit rigid pre-manufactured assemblies.
Modular Construction
For projects that might need reconfiguration or partial disassembly, mechanical connections provide significant advantages. This is increasingly important as the construction industry shifts toward more modular and sustainable approaches.
The Math: Time and Cost Savings That Actually Add Up
Let's talk numbers, because this is where the real business case emerges.
Traditional Welded Approach:
Factory lead time: 2-3 weeks
Transport cost for 4m assembly: Higher (weight + volume)
Site setup time: Variable (depends on accuracy)
Adjustment capability: Limited/Impossible
Rework potential: Significant
Mechanical Cleat System:
Lead time: Standard stock availability
Transport cost: Lower (lighter components)
Site setup time: Predictable (standard assembly)
Adjustment capability: Easy and unlimited
Rework potential: Minimal
On a typical residential project with 8-10 posts, you're looking at potential savings of several hours on the critical path. On commercial projects? The scheduling benefits compound significantly.
One local builder told us: "We used to budget a day for minor adjustments and rework on every project. Now it's 30 minutes. That's not just money—it's peace of mind."
What the Engineers Say
The technical team at SHS Cleats has pursued engineering certification across Australia for exactly this reason. Their cleats undergo laboratory testing to verify load capacity and structural integrity under various conditions.
The certifications ensure that:
Load ratings are verified: Not estimated or assumed
Connection reliability is proven: Through actual testing, not just calculations
Local standards are met: Australian Building Standards compliance isn't theoretical—it's documented
If you're an engineer, architect, or designer specifying structural components, this level of verification matters. You're not just buying components; you're getting engineered solutions backed by testing and certification.
The Environmental Angle (Because It Matters)
Here's something that doesn't get discussed enough: the sustainability advantage of mechanical connections.
Factory welding consumes energy. Transport of heavier pre-assembled units generates emissions. Site rework and waste add environmental cost. A system that:
Reduces manufacturing steps
Decreases transport weight
Minimizes on-site waste and rework
Allows for disassembly and reuse
...is genuinely more sustainable. This isn't greenwashing. It's just how the physics works out.
For developers and builders increasingly focused on sustainability credentials, this is worth considering.
Common Questions Answered
Q: Are mechanical cleats really as strong as welded connections?
A: Yes, when properly engineered and certified. The key difference is flexibility, not strength. Once secured, they perform identically.
Q: What if we need to change connections during construction?
A: That's actually the point. Unlike welded assemblies, you can make adjustments. This is a feature, not a limitation.
Q: Does this work for all SHS sizes?
A: Mechanical systems are available for standard SHS sizes from 65x65mm through 200x200mm. These cover the vast majority of construction applications in Australia.
Q: What about costs? Are they more expensive?
A: Usually less expensive, when you factor in reduced transport costs, eliminated rework, and scheduling efficiency.
Making the Transition: What You Need to Know
If you've been using traditional welded systems and are considering a shift to mechanical cleats, here's the practical reality:
Your existing suppliers can still provide the components—you're just specifying them differently
Your site teams will actually prefer the flexibility—once they experience it
Your design and engineering process changes slightly—but usually becomes simpler
Your scheduling becomes more predictable—because you control positioning on site
The transition isn't disruptive. It's genuinely additive.
The Bottom Line
The construction industry has a tendency to resist change. We do things a certain way because "that's how we've always done it." But occasionally, something comes along that's genuinely better—faster, more flexible, more cost-effective, and more controllable.
Mechanical SHS cleat systems represent exactly that kind of innovation.
Whether you're managing a small residential build or a large commercial project, whether you're concerned about scheduling, cost, or flexibility—mechanical cleats deserve serious consideration in your next project specification.
The future of structural connections isn't about choosing between quality and flexibility. It's about getting both.

The Future of Construction Isn’t Complicated — It’s Just Smarter
Meta Description: Discover how adjustable SHS cleats are changing real construction work across Australia — faster installs, fewer delays, and less on-site stress.
It Was Meant to Be a Quick Job…
We thought it would take half an hour.
One beam. One connection. Simple.
But the levels were slightly off… maybe 10–15mm. Nothing major — but enough to cause a problem.
Next thing you know, we’re cutting, adjusting, checking again… and waiting.
By the time it was sorted? Half a day gone.
If you’ve worked on a real job site in Australia, you already know — things rarely go exactly to plan.
The Old Way Still Works… Until It Doesn’t
For years, the process hasn’t changed much:
Fabricate everything in the factory
Weld connections precisely
Deliver to site
Install and hope it fits perfectly
And when everything lines up — it works.
But when it doesn’t… that’s where things slow down.
What Actually Happens on Site
Let’s be honest for a second:
Concrete isn’t always perfectly level
Measurements shift slightly
Site conditions change
Designs don’t always match reality
And when that happens?
You’re stuck doing this:
Cut
Re-weld
Adjust
Wait
Every step costs time. Every delay adds pressure.
So What Changed?
At some point, the question shifted:
“Why are we fixing everything in the factory… instead of adjusting it on-site?”
That’s where adjustable SHS cleats came in.
If you’ve ever looked into what SHS cleats actually are and how they work, you’ll realise it’s not some complex innovation… it’s just practical.
How It Works (Simple, No Fuss)
Here’s the process:
Install your SHS columns
Slide the cleat to the required height
Fix your beam
Done
Need to adjust?
Loosen → slide → tighten
No cutting. No delays. No frustration.
Real Impact on Site
Brisbane Verandah Project
Size: 20m × 4m
8 beam connections
Traditional method: ~48 hours Using cleats: ~4 hours
That’s not a small improvement — that’s a completely different workflow.
And this is exactly why many builders are now exploring why SHS cleats are becoming a game changer in modern construction.
The Big Advantage: Control
With traditional methods:
You depend on factory precision
With cleats:
You adapt on-site
That control changes everything.
Why This Works So Well in Australia
Remote job sites
Labour shortages
Rising costs
So anything that saves time = real value.
And when you look at modern connection solutions available today, it’s clear the industry is slowly shifting.
What About Strength?
Yes — properly installed cleats are:
Engineered
Standards-compliant
Flexible in fixing (screws / bolts / welds)
No compromise on strength.
Where It Makes the Most Difference
Verandahs & decks
Residential builds
Small commercial projects
Steel frame structures
Thinking of Using This on Your Next Project?

The Bottom Line
Most construction delays don’t come from big problems…
They come from small misalignments.
And if you can fix those quickly — Everything else moves faster.
How to fill the gender gap in the construction
The construction industry is one of the largest top job-generating industries in our country. And it’s also the second most male-dominated (behind mining). According to the Workplace Gender Equality Agency (WGEA), just 27% of the workforce are women.
And while it’s easier said than done, there are many ways to ensure we close the gender gap and become champions of change. Read more: http://bit.ly/3SzwKQD
