U / C Channel Metal Steel
C Channel steel is a steel profile with a U-shaped cross-section, consisting of a flat base (web) and two parallel vertical sides (flanges). Often called a "C channel" due to its resemblance to the letter "C," it provides excellent rigidity and is widely used for structural support, framing, and edge protection. |
RUNYING Steel Group is a trusted Tangshan-based manufacturer and exporter of structural U / C Channel Metal Steel Profiles. Engineered with a U-shaped cross-section—comprising a solid flat base (web) and two perpendicular flanges—our steel channels provide exceptional lateral stiffness, high moment of inertia, and reliable load-bearing performance for heavy structural framing, transport equipment, and infrastructure projects worldwide.
Produced under strict ISO 9001 manufacturing quality systems, our mild and high-tensile carbon steel channels comply fully with Chinese GB (GB/T 707) and Japanese JIS (JIS G3192) national manufacturing standards.
High Strength-to-Weight Ratio:
Optimized web-to-flange geometry ensures maximum bending resistance while keeping total structural weight minimal for easier installation and transport.
Superior Weldability & Fabricability:
Manufactured from premier carbon steel billets (Q235B, Q355B, SS400 grade equivalents), allowing seamless site welding, precision punching, and flame cutting.
Versatile Surface Protection Options:
Avilable in Black Mild Finish, Anti-Rust Varnished, or Hot-Dip Galvanized (HDG) finishes to withstand severe atmospheric and marine corrosion.
Building Frameworks & Civil Works: Industrial plant columns, roof truss purlin supports, warehouse mezzanine floors, and stair stringer channels.
Vehicle & Transportation Engineering: Truck chassis frames, trailer side rails, crane gantry support tracks, and agricultural machinery beds.
Machinery & Equipment Manufacturing: Heavy conveyor system guide rails, equipment base plates, and industrial storage shelving racks.
Construction Edging: Edge protection and perimeter framing for doors, window frames, and precast concrete wall panels.
