Structural Steel Angles Sydney

At Cedar Steel, we supply a complete range of structural steel angles Sydney builders rely on for strength, uniformity, and compliance. All our angles are sourced from reputable Australian mills and processed using strict quality controls.

Our core range includes:

• Equal steel angle
• Unequal steel angle
• Structural steel angle
• Hot-rolled L steel angle
• Galvanised angle steel
• Custom-cut and fabricated angles

Each angle is manufactured to AS/NZS 3679.1 standards, ensuring consistent dimensions, mechanical properties, and performance.

Equal angles feature two legs of identical length, providing a balanced distribution of load and strength. They are ideal for:

• General structural support
• Bracing frameworks
• Fabrication and welding projects
• Shelving and racking systems
• Architectural steel members

Common Equal Angle Sizes

A selection of typical equal angle dimensions includes:

• 20 × 20 × 3 mm
• 50 × 50 × 5 mm
• 75 × 75 × 6 mm
• 100 × 100 × 10 mm
• 150 × 150 × 12 mm

Custom lengths and processing options (cutting, punching, priming, galvanising) are available upon request.

Unequal angles feature two legs of differing lengths, designed to handle structural loads where directional strength is required. They are widely used in:

• Large-scale commercial & civil structures
• Steel frameworks for industrial projects
• Structural bracing systems
• Reinforcing columns and beams
• Architectural steel detailing

Typical Unequal Angle Sizes

Examples include:

• 65 × 50 × 5 mm
• 100 × 75 × 8 mm
• 125 × 75 × 10 mm
• 150 × 100 × 12 mm
• 200 × 150 × 15 mm

These sizes allow engineers to optimise structural performance without unnecessary weight or material usage.

To ensure longevity and structural integrity, Cedar Steel offers multiple material grades and protective coatings:

Available Grades

• 300+ MPa and 350 MPa structural steel
• Hot-rolled angle steel
• Galvanised angle steel
• Stainless steel options (304/316 for corrosive environments)

Surface Finishes

• Untreated mill finish
• Hot-dip galvanised
• Primed / red oxide
• Custom coatings upon request

Each finish is selected to enhance corrosion resistance, durability, and long-term performance.

We provide complete processing solutions to meet project requirements with precision and speed. Our fabrication services include:

Fabrication Capabilities

• Cut-to-length processing
• Mitre cutting and angled cuts
• Drilling, notching and punching
• Welding and assembly
• Galvanising and protective coatings
• Delivery via our specialised transport vehicles

These solutions enable seamless integration into commercial, residential, and industrial construction workflows.

1. Commercial & Industrial Construction

Steel angles are commonly used in:

• Building frames
• Roof trusses
• Industrial walkways
• Conveyor systems
• Mechanical platforms

Their ability to carry both compression and tension loads makes them indispensable in these environments.

2. Residential & Architectural Builds

Designers and builders use steel angles for:

• Lintels and supports
• Stair frames
• Window and door frames
• Custom architectural elements

3. Infrastructure & Civil Projects

Engineers specify structural angles for:

• Bridges
• Retaining walls
• Civil reinforcement
• Utilities infrastructure

Their strength-to-weight ratio provides exceptional performance in demanding outdoor environments.
