Long Steel U Channel S275JR Q235B Q345B JIS SS400 Structural Steel Channel
Long Steel U Channel S275JR Q235B Q345B JIS SS400 Structural Steel Channel
１．Product Overview
Steel U channel is widely used in structural steel fabrication, industrial buildings, equipment supports, machinery frames, and infrastructure projects. The channel-shaped section provides reliable load-bearing performance while maintaining efficient steel consumption.
This product is manufactured according to JIS G3101 SS400, ASTM A36, EN10025 S275JR, GB700 Q235B, and Q345B standards for international structural applications.
２．Technical Solution
Hot rolled U channel steel is designed for structural support and frame reinforcement. The channel section improves bending resistance and structural stability under vertical and horizontal loads.
Different steel grades are available for light structural fabrication, medium-duty steel frames, and heavy industrial structures.
SS400 and ASTM A36 are commonly selected for general structural fabrication, while Q345B and S275JR provide improved yield strength for demanding engineering projects.
