Buy Structural Steel Angles Online
Custom-cut to Order Delivery or Click & Collect
Structural steel angles (often referred to as angle iron, L-angle or L-bracket) are L-shaped steel sections that are essential in construction and fabrication projects.
Equal angles have both legs of the “L” the same length, whereas unequal angles have differing leg lengths to suit specific design needs. Despite this difference, both types feature a 90° angle and provide excellent versatility, strength, and structural support at a competitive price point. These qualities make structural steel angles fundamental components for frames, bracing, shelves, lintels and more in all kinds of builds.
At Edcon Steel, we offer a comprehensive range of both equal and unequal angle profiles, reflecting our status as Australia’s most comprehensive online steel and metal store.

Key Specs & Options: Structural Steel Angles
| Specification |
Details |
| Equal Angles – Size Range | Leg lengths from 25 x 25 mm up to 200 x 200 mm (approx. 1″ x 1″ up to 8″ x 8″). Thicknesses range from 3 mm on smaller angles to 26 mm on the largest standard sections. These cover small-angle irons for light fabrication through to heavy structural angles. |
| Unequal Angles – Size Range | Leg lengths from 75 x 50 mm up to 150 x 100 mm (approx. 3″ x 2″ up to 6″ x 4″). Thicknesses generally range from 5 mm to 12 mm for these sections. Unequal angles provide flexibility where one leg needs to be longer for support or attachment. |
|
Materials Available |
– Mild Steel – Hot-rolled 300PLUS structural steel (min 300 MPa yield) for maximum strength. – Pre-Galvanised Steel – e.g. Duragal® angles (C450 grade) with a light zinc-aluminium coating for internal/external use. – Hot-Dip Galvanised – Mild structural steel angles coated to AS/NZS 4680 standard for full zinc protection (ideal for outdoors). – Stainless Steel – 316 Grade marine grade stainless angles for superior corrosion resistance in harsh environments. – Aluminium – 6060-T5 alloy angles for a lightweight, non-rusting option (suitable for light frames, not structural load-bearing). |
| Finishes / Coatings | Mill finish (raw, uncoated steel with mill scale) is standard for most hot-rolled angles. Customers can optionally get angles primed/painted (anti-rust primer or other paint) or Hot-Dip Galvanised (HDG) for corrosion protection. Galvanising adds a zinc coat ~85 µm thick, bonding to the steel – perfect for exterior use. Stainless angles come in a mill finish (dull gray) unless polished. |
|
Stock Lengths |
Standard stock lengths are 6.0 m for smaller merchant-bar angles and 9.0 m or 12.0 m for larger structural angles. Some sections may also be available in lengths of ~8 m or 6.1 m. Edcon Steel offers custom cutting on all angles – we will supply any length you require, so you don’t have to buy more than you need. Standard long lengths can be delivered or collected from our branches. |
|
Mass (Weight) per Length |
Unit weight depends on size and thickness. For example, a 25 x 25 x 3 mm mild steel angle is about 1.12 kg per metre, whereas a hefty 200 x 200 x 26 mm angle is ~76.8 kg per metre. Most structural angles fall in between these extremes. |
|
Standards |
Edcon’s structural steel angles conform to AS/NZS 3679.1 (Grade 300) for hot-rolled structural steel. This ensures consistent mechanical properties and quality. Hot-dip galvanising meets AS/NZS 4680 for zinc coatings. Stainless structural steel angles meet ASTM standards (e.g. ASTM A276 for 316 profiles). Certifications can be provided upon request. |

Work Smarter with Edcon Steel
Plan Your Lengths: Planning your project around these sizes minimises offcuts and saves on cost. Our team can custom-cut to your specs for maximum value.
Match the material to the job: If your project is outdoors or damp, consider galvanised steel or stainless structural steel angles so you won’t have to worry about rust. In coastal/marine environments or for food-grade projects, 316 stainless angles are worth the investment for their superior corrosion resistance. Always ensure you’re using structural-grade steel (300 MPa) for load-bearing applications, and if weight is a concern (or the angle isn’t structural), lightweight aluminium angles might be an option.
Store steel properly to prevent damage: Keep structural steel angles dry and off the ground during storage. If they’re delivered to site before use, place them on timber skids or racks to prevent moisture accumulation and ground contact, which can lead to rust.
For long-term storage of mill finish (uncoated) angles, consider applying a light oil or corrosion inhibitor spray to the surface – this provides temporary rust protection.
Cut & Handle Safely: Always wear PPE and de-burr sharp edges after cutting. Don’t have the right tools? We’ll cut it for you with clean, accurate finishes, either while you wait in-store or with your online order.
Check with a Professional: All information here is general. Always confirm your steel sizes and load requirements with a qualified engineer or builder before installation to ensure compliance and safety.
Common Uses and Sectors: structural steel angles
Structural steel angles are a go-to solution across many industries thanks to their strength, versatility, and ease of use. In construction, they serve as lintels, purlins, framing components, and wall supports in both residential and commercial projects. Infrastructure and mining sectors use equal and unequal angles for cross-bracing, gantries, towers, and support frames where durability is critical.
In manufacturing and fabrication, angles form machinery bases, shelving, benches, and racking systems. Their simple profile makes them easy to cut, weld, and bolt. Transport and automotive projects rely on angles for trailer chassis, vehicle frames, and 4×4 builds, while marine and coastal applications benefit from corrosion-resistant stainless steel options.
DIYers and farmers use mild structural steel angles for gates, brackets, garden beds, and shed frames due to their affordability and workability.
Whether for structural builds or smaller projects, Edcon Steel supplies angle solutions for every job—backed by decades of experience across Australia’s construction, mining, infrastructure, and industrial sectors.

Where can I buy structural steel angles in Sydney?
Edcon Steel has stores in Brookvale, Revesby, and Blacktown. You can also order online 24/7 for delivery across Sydney and NSW. Our team can help you choose the right angled product for your project.
Do the Orange and Bathurst stores stock structural steel angles?
Yes. Our regional NSW stores in Bathurst and Orange stock a wide range of steel equal and unequal angles. If a specific size isn’t in stock, we can quickly transfer it from another branch or arrange delivery from our central warehouse.
How much do structural steel angles cost?
Steel angle pricing varies depending on the size (dimensions and thickness), the material and grade (mild steel vs galvanised vs stainless), and the finish. Generally, larger and thicker angles cost more per metre due to the greater material volume, and stainless structural steel angles are priced higher than mild steel due to the alloy content and manufacturing process. You can view live pricing and stock availability on our website or request a quote from your nearest store. We sell by the length you need, so you only pay for what you use.
What lengths of structural steel angles can I buy?
Edcon Steel carries extensive stocks of standard angle sizes. Popular sizes are usually available for immediate purchase at our store locations (Brookvale, Revesby, Blacktown, Bathurst, and Orange). Less common profiles or very large sections might be stocked at one central location or available on order with a short lead time (our team can advise on availability).
Any tips for using and maintaining structural steel angles?
Design around standard lengths to reduce waste and cost. Choose galvanised structural steel angles for outdoor or coastal jobs to prevent rust. 316 stainless steel angles are often the best choice in coastal or marine environments with salt exposure. If using plain mild structural steel angles outside, apply a protective coating (primer + paint system or a surface treatment) and be prepared for periodic maintenance, as bare mild steel will rust when exposed to moisture.
