Custom-cut to Order Delivery or Click & Collect

At Edcon Steel, we supply a comprehensive range of steel flat bars to suit projects of any size. Our flat bars are made from high-quality mild steel (Grade 300+), ensuring reliable strength and performance.

Our stock also includes high-tensile pre-galvanised flat bar (Duragal® C450L0) for extra strength and built-in corrosion resistance, as well as options in hot-dip galvanised or primed (painted) finishes for added durability. Stainless steel flat bars (grades 304 and 316) are also available for specialised applications that require superior corrosion resistance or a polished look.

Steel flat bars (also called flat steel bars or flat bar stock) are rectangular, solid metal sections with a flat profile. Thanks to their simple shape and full-density steel cross-section, flat bars are highly versatile for a wide range of construction and fabrication projects.

Order online for nationwide delivery, or visit our NSW stores in Brookvale, Revesby, Blacktown, Bathurst, and Orange for expert advice and local pick-up.

Work Smarter with Edcon Steel

Plan Your Cuts: Steel flat bar is typically stocked in 6m lengths. Plan your project around this when possible to minimise waste and save on cost. Our team can help you optimise your cuts to get all your required pieces out of the fewest bars.

Weld or Fasten correctly: Drill clean holes for bolts and use washers for support. Before welding, remove coatings from the galvanised flat bar and reapply after welding.

Choose the Right Finish: Use mill or primed flat bar for indoor work. For outdoor or coastal areas, opt for hot-dip galvanised or Duragal flat bar. Need long-term rust resistance or a clean finish? Stainless steel is ideal for use in marine and food-grade applications.

Cut & Handle Safely: Always wear PPE and work in a well-ventilated area. 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: Steel Flat Bar

Steel flat bar is widely used across numerous industries for structural support and fabrication. In construction, it functions as brackets, cleats, and base plates, strengthening beams, columns, or timber structures. Its flat profile makes it ideal for bracing frameworks or flush mounting against surfaces.

Flat bar is commonly used in rural and DIY projects, such as forming gate frames, fence posts, shed bracing, benches, or garden edging. Outdoor uses often utilise galvanised or primed flat bar for rust resistance in harsh weather.

Industrial and infrastructure applications rely on flat bar as connector plates, stiffeners, gusset plates, and machine parts due to its solid strength and load-bearing capacity. Similarly, the transport and marine sectors use flat bar for trailer frames, truck bodies, and boat fittings (often choosing stainless steel for corrosion resistance).

Overall, steel flat bar is valued for its strength, versatility, and ease of use for projects ranging from small DIY tasks to heavy engineering projects.
