Buy Steel C-Section - Channel Online
Custom-cut to Order Delivery or Click & Collect
Steel C-Section Channels (also known as Parallel Flange Channels or PFC) are steel beams shaped like the letter “C” in cross-section. They consist of a vertical web and two horizontal flanges, resulting in a flat back surface and an open channel on the other side. This shape gives C-section channels a high strength-to-weight ratio and makes them easy to bolt or mount to other flat surfaces.
At Edcon Steel, we supply a comprehensive range of steel C-section channels to suit any project. Our channels are made from high-quality mild steel (Grade 300+) and are often Australian-made, meeting all relevant Australian Standards.
We also offer pre-galvanised high-tensile channels (Duragal® C450L0) for extra strength and corrosion resistance, as well as options in hot-dip galvanised or primed (painted) finish for durability.
Order online for nationwide delivery, or visit one of our stores in NSW (Brookvale, Revesby, Blacktown, Bathurst, and Orange) for expert advice and local pick-up.

Work Smarter with Edcon Steel
Plan Your Lengths: C-section channels are typically stocked in 9 m and 12 m lengths. Planning your project around these sizes minimises offcuts and saves on cost. Our team can custom-cut to your specs for maximum value.
Choose the Right Finish: Mill (raw) or primed steel channels are usually sufficient for indoor or sheltered projects. Choose hot-dip galvanised or Duragal® pre-galvanised channels for lasting rust protection for outdoor, coastal, or high-moisture environments.
Cut & Handle Safely: Always wear PPE when cutting steel. De-burr sharp edges after cutting to prevent injury and ensure a clean fit. Don’t have the right tools? We’ll cut your channel to precise lengths — while you wait in-store or as part of your online order.
Join Smartly: For bolted assemblies, we stock a wide range of plates, cleats, and brackets to help you create strong connections. If welding, remember to remove zinc from galvanised surfaces first and re-coat afterwards to maintain corrosion protection.
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 C-Section - Channel
Steel C-section channels are vital structural components used in residential, commercial, and industrial construction. In building projects, they serve as lintels above doors and windows, floor joists, roof purlins, rafters, bearers, and bracing members. Their flat back makes them easy to bolt to walls, concrete, or timber—ideal for columns, beams, and frames that require clean mounting.
With a high strength-to-weight ratio, C-channels support heavy loads, like roof trusses or mezzanines, without adding unnecessary mass. They’re also a top choice for outdoor and secondary structures, including carports, pergolas, garages, and sheds.
Galvanised options are especially popular for long-term corrosion protection in coastal or high-moisture areas.
Beyond construction, C-section channels are used in infrastructure and industrial settings, from bridge trusses and platforms to equipment frames. They’re also common in manufacturing, mining, and agriculture for machinery bases, trailer chassis, and fencing posts. Whether tackling a home DIY or a large-scale build, C-section channels offer reliable, easy-to-install strength across all sectors.

What lengths of C-section channels can I buy?
We stock standard 9 m and 12 m lengths, but we can cut to any size you need. Our precision saw-cutting service ensures clean, accurate edges, whether you need full lengths for framing or short sections for fabrication work.
Any tips for using and maintaining steel C-section channels?
Design around standard lengths to reduce waste and cost. Choose galvanised or Duragal® channels for outdoor or coastal jobs to prevent rust. Always wear PPE when cutting or drilling, and de-burr edges for a clean finish. If welding galvanised steel, remove the zinc coating in the weld area and re-coat after for continued protection.
