Understanding RHS & SHS Steel in Melbourne

June 2, 2025

Brimbank Steel understands the vital role steel plays in the construction and manufacturing industries across Australia. When it comes to durable and versatile materials, RHS & SHS steel in Melbourne continues to be a popular choice for builders, fabricators, and engineers alike. But what exactly are RHS and SHS, and why are they preferred?

In this blog, we’ll explore the structure, applications, and benefits of RHS (Rectangular Hollow Section) and SHS (Square Hollow Section) steel. We’ll also share how to choose the right material for your project and where to source reliable steel supplies in Melbourne. Please call us at (03) 9364 5892.


Applications and Benefits of RHS & SHS Steel

RHS (Rectangular Hollow Section) steel is characterised by its elongated rectangular shape, offering strength along its longer axis, which makes it ideal for columns, beams, and frames where directional strength is required. In contrast, SHS (Square Hollow Section) provides a symmetrical profile, making it perfect for balanced load distribution in general construction and architectural design.

Both RHS and SHS offer several benefits:

• High strength-to-weight ratio: Ideal for modern builds demanding structural integrity without excess weight.

• Aesthetic versatility: Their clean lines and uniform shapes make them appealing for exposed architectural features.

• Ease of welding and fabrication: Their consistent shape and thickness allow for smoother joins and consistent finishes.

• Corrosion resistance (when galvanised): Extended lifespan in outdoor and industrial settings.

Whether you're constructing support frames, trailers, furniture, or fencing, RHS & SHS steel in Melbourne are go-to options for reliable performance and visual appeal.


Choosing the Right Steel for Your Project

When selecting RHS or SHS steel, consider factors such as load-bearing requirements, environmental exposure, and finish preferences. For instance, galvanised sections are ideal for coastal or outdoor projects due to their increased corrosion resistance.

Dimensions and thickness also matter. Lightweight SHS may be sufficient for balustrades or gates, while a more robust RHS may be needed for commercial framework or platforms. Consulting with knowledgeable steel suppliers in Melbourne helps ensure you're using the right steel grade and profile to meet Australian Standards.


Why Local Sourcing Matters

Sourcing steel supplies in Melbourne ensures not only fast delivery but also compliance with local regulations and building codes. Local suppliers understand regional requirements and can offer technical guidance for optimal results. Plus, it reduces lead times, costs, and carbon footprint associated with long-distance shipping.

By partnering with Melbourne-based suppliers, builders and fabricators can streamline their operations and maintain high standards of quality and safety.


Real-World Examples of RHS & SHS Steel Usage

• Residential Projects: SHS is often used for balcony railings, fencing, and decorative structures thanks to its clean look and uniform strength.

• Industrial Facilities: RHS is favoured in warehouses and workshops for framework and structural supports.

• Transport Fabrication: Trailer manufacturers often rely on RHS and SHS for chassis and subframe builds due to their strength and weldability.

These applications highlight how adaptable and efficient hollow steel sections are across a range of industries.


Conclusion:

When it comes to RHS & SHS steel in Melbourne, quality, compliance, and expert advice are key to successful outcomes. Whether you're a project manager, fabricator, or builder, trust a local supplier to deliver premium steel supplies in Melbourne tailored to your needs.
