Carbon Steel Channel Overview
Carbon Steel Channel is one of the most widely used structural steel sections in modern construction, infrastructure, machinery manufacturing, transportation equipment, and industrial engineering projects. Its U-shaped cross-section provides excellent load-bearing performance, high bending resistance, and efficient weight-to-strength ratio.
At Xi'an Dongmeng Group Co., Ltd, we manufacture and export hot rolled carbon steel channels in accordance with ASTM, EN, JIS, and GB standards. Our channels are available in ASTM A36, ASTM A572, Q235B, Q345B, S235JR, S275JR, and S355JR grades, making them suitable for structural frameworks, support systems, equipment bases, bridge structures, solar mounting systems, and industrial platforms.
With advanced rolling mills, strict quality control procedures, and global logistics capabilities, we supply steel channels to customers throughout North America, Europe, the Middle East, South America, and Southeast Asia.
Carbon Steel Channel, also known as C-Channel, U-Channel, or Structural Channel, is a hot-rolled or cold-formed steel profile widely used in building structures, machinery frames, bridges, and industrial fabrication.
