Benefits of Using Galvanised SHS Cleats for Timber Connections

Introduction

When it comes to modern construction, especially in mixed-material structures that combine timber and steel, reliability and strength in connections are critical. The SHS (Square Hollow Section) Cleat has quickly become a preferred solution for builders, engineers, and fabricators across Australia.

But what sets galvanised SHS cleats apart from traditional connection methods? Why are they considered one of the most secure and cost-effective options for timber-to-steel connections?

In this post, we’ll dive into the key benefits of using galvanised SHS cleats, explore how they simplify installation, extend the life of timber structures, and help you meet Australian building standards — all while maintaining a professional, safe finish.

What Are SHS Cleats?

SHS cleats are engineered steel brackets designed to connect timber beams, PFC beams, or bracing rods to SHS steel columns or frames. They are typically fabricated from galvanised steel, offering high tensile strength and corrosion resistance.

Each cleat is precision-designed to align with SHS (Square Hollow Section) dimensions — ensuring perfect fitment and stability.

At SHS Cleats Australia, every product is designed and patented to meet PCT standards, meaning they are tested for real-world performance, load-bearing capacity, and long-term durability.

1. Exceptional Strength and Stability

The most obvious advantage of using SHS cleats is superior structural stability.

• Each cleat is designed to distribute loads evenly between the timber beam and the steel section.
• Unlike welded or direct bolt connections, cleats minimise stress concentration, reducing the risk of joint failure.
• Galvanised SHS cleats are fabricated using high-grade steel, making them ideal for both domestic and industrial applications.
  

In other words, when your structure relies on the connection, you can rely on the cleat.

2. Long-Lasting Corrosion Protection (Hot-Dip Galvanisation)

In Australia’s diverse climates — from humid coastal regions to dry inland zones — corrosion is a major concern in structural applications.

This is where galvanised SHS cleats shine.

• Each cleat undergoes hot-dip galvanisation, a process that coats the steel with a protective layer of zinc.
• This zinc barrier prevents rust, oxidation, and degradation even in outdoor environments.
• Unlike painted or powder-coated steel, galvanisation protects inside and out, covering all edges, holes, and welds.
• Our cleats have 500 grams per sq. metre coverage of hot dip galvanising on our products, enough to suit coastal living.

The result? Cleats that last for decades with minimal maintenance — an investment in both quality and peace of mind.

3. Simplified Installation and Alignment

Traditional methods of connecting timber to steel often involve multiple components, including angle brackets, bolts, washers, and welding, which can be time-consuming and error-prone.

SHS cleats simplify everything.

• They are designed to fit seamlessly over standard SHS sections.
• Pre-drilled holes ensure quick alignment and precise bolt placement.
• No need for on-site welding if shear loads are less than 45kN or custom fabrication.

Whether you’re installing a timber pergola, floor bearer, roof beam, or verandah beam, SHS cleats reduce both labour and installation time — keeping your project on schedule and within budget.

4. Compliance with Australian Standards

Safety and compliance are non-negotiable in construction.

All SHS cleats offered by SHS Cleats Australia are manufactured to comply with AS 4100 and other relevant structural steel design codes.

This means:

• Each cleat is tested for load capacity and fitment accuracy.
• Engineers and builders can specify them confidently in their designs.
• You maintain full compliance with Australian building regulations — without extra paperwork or testing.

5. Perfect for Timber Connections

One of the biggest advantages of SHS cleats is their ability to bridge the gap between two different materials — timber and steel.

• The cleat provides a secure interface where timber beams can be bolted or screwed directly onto the SHS column.
• The galvanised finish prevents reaction with treated timber chemicals.
• The mechanical connection allows for flexibility and movement, reducing timber splitting or joint cracking over time.

Whether you’re working on floor bearers, balconies, or verandahs, these cleats ensure your timber elements stay stable and aligned.

6. Versatility Across Construction Applications

galvanised SHS cleats are used in a wide range of structural applications:

• Timber-to-SHS connections
• SHS-to-SHS column or beam joins
• Steel framing systems
• Pergolas, verandahs, sheds, and modular structures
• Light industrial and commercial projects

Because they are modular and prefabricated, SHS cleats can be integrated into both new builds and retrofits, offering complete flexibility to architects, engineers, and fabricators.

7. Reduced Maintenance and Lifecycle Costs

Galvanised SHS cleats don’t just perform well initially — they continue to do so for years.

Thanks to their corrosion resistance and mechanical strength, they rarely require replacement or maintenance.

That means:

• Lower lifetime cost of ownership.
• Reduced downtime for repairs.
• Better ROI compared to non-galvanised or custom-welded brackets.

In environments such as coastal zones or industrial plants, this durability directly translates into cost savings.

8. Precision Design and Aesthetic Appeal

Modern architecture often leaves structural elements exposed — and galvanised SHS cleats fit beautifully into that aesthetic.

• The clean, symmetrical design complements both timber and steel.
• The matte zinc finish adds an industrial yet premium look.
• Engineers appreciate the precision, while designers love the visual detail.

It’s a small component that makes a big visual impact — and one that speaks to craftsmanship and attention to detail.

9. Engineered and Tested for Safety

Every cleat from SHS Cleats Australia undergoes strict quality testing for strength, alignment, and performance.

Because these are PCT-patented designs, you get the assurance that the cleats have been validated in real structural scenarios.

That means no guesswork, no site improvisation — just tested reliability that engineers can trust and builders can install confidently.

10. Sustainable and Environmentally Friendly

Sustainability is now a major focus in construction.

Using galvanised steel cleats supports sustainability by:

• Reducing waste (longer lifespan = fewer replacements).
• Being fully recyclable at the end of life.
• Eliminating the need for chemical coatings or treatments.

This makes SHS cleats not just strong and practical — but also eco-conscious.

Why Australian Builders Prefer SHS Cleats

Australian builders, architects, and engineers increasingly prefer SHS Cleats because they blend simplicity, strength, and compliance into one cost-effective solution.

Unlike imported or custom-fabricated brackets, locally engineered SHS cleats are designed for Australian SHS sizes and load standards, ensuring reliability and faster delivery.

When your project demands both form and function — SHS Cleats Australia delivers.

Conclusion

The benefits of using galvanised SHS cleats for timber connections go far beyond convenience — they represent engineering precision, safety, and longevity.

From corrosion resistance and fast installation to compliance and sustainability, these cleats are built to perform in Australia’s toughest conditions.

If you’re designing or building timber structures with SHS steel columns, there’s no better choice for connection hardware.
