Equal Steel Angles Sydney – Perfect Balance for Universal Applications

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 Steel Angles Sydney – Optimised Strength for Load-Bearing Applications

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.

Material Grades & Surface Finishes for Every Environment!

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

Available Grades

  • 300+ MPa and 350 MPa structural steel
