At Edcon Steel, we stock a comprehensive range of steel square bar in different sizes and finishes to suit jobs big or small. Most of our square bar is Australian-made 300PLUS® grade mild steel,which means consistent quality and compliance with Australian Standards.
Steel square bar is a solid steel profile with equal-width sides, forming a perfect square in cross-section. This simple but sturdy shape is widely used in construction, fabrication, and general engineering. Its strength and versatility make it a go-to choice for projects ranging from industrial frameworks to decorative metalwork.
Tradespeople value steel square bar for its reliability in structural bracing, gates, and supports, while DIY enthusiasts appreciate how easily it can be cut, welded, or drilled for home improvements.

Key Specs & Options: Steel Square Bar
| Specification | Details |
|---|---|
| Dimensions (Across Flats) | ~6 mm square (smallest standard) up to ~75 mm square (largest commonly stocked). Intermediate sizes available in both metric and imperial equivalents.* |
| Material Types | Hot-rolled mild steel (Grade 300+) for general use (strong, weldable, great for most projects).
Bright Mild Steel 1020 (cold-finished) for a smoother surface and tighter tolerances – ideal for precision work. Medium Tensile Carbon Steel 1045 for higher-strength engineering applications. Stainless steel (304/316) square bar available by request for superior corrosion resistance (often used in marine and food industries). |
| Available Finishes | Mill finish (black, uncoated raw steel) is standard for mild steel.
Hot-Dip Galvanised (HDG) available in select sizes for long-term corrosion protection (zinc-coated after fabrication). Primed/Painted finish can be arranged on request (e.g. red oxide or zinc primed) to provide a ready-to-paint surface and basic rust prevention. |
| Stock Lengths | Standard stock length is 6.0 m for most mild steel square bars.
Bright mild steel bars often in 3.0 m or 4.0 m lengths. Edcon also provides convenient pre-cut 1.0 m and 2.0 m sections in popular sizes at our stores (subject to availability) – perfect when you need a quick piece without full-length purchase. |
*Sizes outside the standard range may be available by special order. Contact us if you have a unique size requirement.

Work Smarter with Edcon Steel
Plan Your Cuts: Most square bars come in 6 m lengths. Designing with this in mind helps reduce off-cuts and save money. Measure twice, and ask our team for help optimising your cut list.
Cut & Handle Safely: Wear PPE and secure your bar firmly before cutting. Use a quality metal saw and de-burr sharp edges. No tools? We’ll cut your steel to size – in store or online.
Guard Against Rust: For outdoor use, choose galvanised square bar or apply primer and paint to raw steel. Indoors, mill finish is fine, but a protective coat adds durability.
Buy Only What You Need: Skip full lengths if you only need a short piece. We cut to size with no minimum order, saving you on both cost and freight. Shorter lengths are cheaper and easier to ship.
Check with a Professional: For structural jobs, confirm size and grade requirements with an engineer or builder. Not sure? Our team can help you choose the right steel for the job.
Common Uses and Sectors: Steel Square Bar
Steel square bar is a versatile material used across residential, commercial, and industrial projects. In building and construction, it’s ideal for formwork, bracing, handrails, fence pickets and security grilles. Its solid profile suits custom tools, pins and components in engineering and manufacturing, while automotive and trailer builders use it for hinge pins, tow hooks, and supports. Farmers and machinery builders rely on it for rugged pins and wear parts, and its clean lines also suit furniture frames and modern metalwork.
From home DIY to infrastructure projects, square bar fits a wide range of jobs. Whether you’re reinforcing concrete, fabricating a gate or repairing farm gear, there’s a size and grade to match. Edcon Steel supplies customers across NSW, from Sydney metro to Bathurst, Orange and beyond, with cut-to-size square bar ready for pickup or fast delivery. With Australia-wide shipping, we make it easy to get the steel you need, wherever you are.
