Hot Rolled Channels
Hot Rolled Channels
A shape is classed a "Bar Size Shape" when its greatest dimension (length excluded) is less than 3 inches. It is a "Structural Shape" when at least one of its dimensions (length excluded) is 3 inches or greater.
- A36 (UNS K02600)
- Low-carbon steel
- Hot-rolled, mill finish
- Excellent weldability
Overview
Hot Rolled Channels, commonly referred to as C channels or structural steel channels, are essential components in commercial and industrial construction across Los Angeles. Manufactured from A36 steel, these channels are formed through a hot rolling process, resulting in a versatile product with excellent strength and machinability. Their distinctive C-shape provides superior load-bearing capacity compared to angles, making them ideal for both vertical and horizontal support applications. This makes them a fundamental choice for projects involving metal roofing, structural frameworks, and heavy-duty fabrication.
At our Los Angeles metal supply center, we stock a comprehensive range of hot rolled channels, from bar size shapes to larger structural shapes. The defining characteristic is simple: a 'Bar Size Shape' has its greatest dimension (excluding length) under 3 inches, while a 'Structural Shape' has at least one dimension of 3 inches or greater. This classification helps contractors, fabricators, and engineers select the correct channel for their specific needs, whether for a corrugated metal roofing system, a support frame for equipment, or as a replacement for galvanized steel fence posts.
The applications for hot rolled channels are vast throughout the LA region. They are the backbone for industrial mezzanines, truck beds, trailers, and agricultural implements. Their ease of welding, cutting, and forming allows for rapid fabrication on-site or in the shop. When your project demands rigidity and durability?from supporting diamond plate sheets to acting as the main runner in a wall system?hot rolled steel channels deliver consistent performance. We serve a wide array of industries, providing not just channels but also complementary products like square tubing, I-beams, and galvanized sheets from our local inventory, ensuring you get all your metal for construction in one place.
Specifications

Values may vary by mill & heat; verify against the MTR for your order.
Applications
- Structural Framing: Primary and secondary support members in building construction.
- Metal Roofing & Siding: Purlins and girts for supporting corrugated metal roofing and PBR metal panels.
- Industrial Fabrication: Bases for machinery, conveyor systems, and storage racks.
- Transportation: Truck beds, trailer frames, and container reinforcement.
- Infrastructure: Bridge components, guardrail supports, and sign structures.
- Agricultural: Equipment frames, building structures, and implement supports.
Weldability
- Welds readily by MIG, TIG, Stick, or Flux-core processes.
- Select filler based on section thickness, joint design, position, and service requirements.
- Remove mill scale in the weld area for best results.
How to Measure
To specify a hot rolled channel, provide three key dimensions: Depth (D) x Flange Width (B) x Weight per Foot (lb/ft). For example, a C10x15.3 channel is approximately 10 inches deep, with a flange width of 2.6 inches, weighing 15.3 pounds per foot. Always measure the depth from the outside of one flange to the outside of the other. The web thickness correlates to the weight designation. For fabrication alongside other materials like diamond plate sheets or galvanized sheet metal, ensure compatibility of dimensions and finishes.
Order Checklist
- Channel designation (e.g., C8x11.5) and required length
- Grade (e.g., A36) and quantity (pieces or total feet)
- Cutting instructions (standard 20'/40' or custom lengths with tolerance)
- Surface finish requirements (as-rolled, cleaned, primed)
- Any certifications (Mill Test Report - MTR) required for traceability
- Special handling or packaging needs
