Hot rolled steel channel, also known as structural channel or C-channel, is a long steel product with a U-shaped cross-section. It is manufactured by heating steel billets and passing them through a series of rollers to form the characteristic channel shape, making it one of the most widely used structural steel sections in construction and engineering projects.

Our hot rolled steel channels are produced in strict accordance with GB/T 706-2016, the Chinese national standard for hot-rolled sections. The channels are available in a wide range of material grades to suit different structural requirements, with Q235B and Q355B being the most commonly used. Q235B carbon steel channels offer excellent weldability, good plasticity, and cost-effectiveness for general structural applications. Q355B low-alloy steel channels provide higher strength (minimum yield strength of 355MPa) and better low-temperature impact resistance, making them ideal for heavy-duty and high-stress applications.

In terms of dimensions, our channels cover a full range of sizes from 5# to 40#, with standard lengths of 6m, 9m, and 12m. The dimensions are specified as height × flange width × web thickness. For example, a 100×48×5.3mm channel has a theoretical weight of approximately 10.0 kg per meter. Additional processing services including cutting, drilling, welding, and galvanizing are available upon request.

Hot rolled steel channels are produced through a well-established rolling process. The production begins with steel billets, which are first heated to approximately 1,200°C in a reheating furnace. The heated billets then pass through a series of roughing and finishing rolling mills. Unlike H-beams which require universal mills, channel steel is rolled using a single set of horizontal rolls. During rough rolling, the billet is gradually shaped into the basic channel profile. In the finishing stage, precision rolls further form the steel into the final U-shaped cross-section with exact dimensions and tight tolerances. After rolling, the channels are cooled on a cooling bed and then straightened to ensure perfect flatness and straightness. Finally, the finished channels are cut to standard lengths (typically 6m, 9m, or 12m) by a flying shear, and undergo rigorous quality inspection including dimensional checks, surface inspection, and mechanical property testing before bundling and storage.

Our hot rolled steel channels are carefully packed to ensure safe delivery to your project site. Channels are bundled by size and length, typically weighing 5-8 tons per bundle for easy handling and container loading. Wooden spacers or steel bars are placed between layers to separate the pieces and prevent surface scratches and friction damage during transit. Special care must be taken when stacking channel steel due to its U-shaped cross-section – channels are stacked in a nested formation (one channel inverted over another) to ensure stability and prevent deformation. High-strength steel strapping is used to secure the bundles tightly. Clear labels are attached to each bundle indicating specification, grade, quantity, and handling instructions. For container shipping, bundles are loaded into standard 20ft or 40ft containers, arranged flat and securely braced with wooden blocks to prevent shifting. For large orders, bulk vessel shipping is also available. All packaging materials comply with ISPM 15 export standards to ensure smooth customs clearance. Customized packaging solutions – including pallet packing, wooden crates, or special labeling – are available upon request.

Hot rolled steel channel is one of the most versatile structural steel profiles, widely used across construction, engineering, and manufacturing industries. In building and civil engineering, channels are used for roof trusses, support beams, floor girders, wall framing, and structural reinforcement. In bridge construction, they serve as cross bracing, stiffeners, and connection components. In machinery manufacturing, channels are used for equipment frames, conveyor supports, machine bases, and brackets. In the transportation sector, they are used for truck trailer frames, railway wagon structures, and shipbuilding components. In the power and telecommunications fields, channels are widely used for transmission tower structures and cable tray supports. Additionally, channels are commonly found in industrial shelving, warehouse racking systems, and as purlins in steel structure buildings. With excellent strength-to-weight ratio, good weldability, and easy formability, hot rolled steel channels are an essential material for a wide range of applications from heavy structural support to general fabrication and maintenance projects.
