C Channel

Product Introduction

• Standard Name: C Channel / Structural Channel.

• Common Names: C-shaped steel, channel steel, C-channel steel, structural channel steel.

• Product Definition: A long steel section with a cross-section shaped like the letter “C.” Classified as a structural steel, it is typically manufactured through hot-rolling or cold-forming processes. Its two flanges provide excellent bending resistance, making it widely used in building structures, mechanical frames, supports, purlins, etc., serving as beams, columns, or guide rails.

C Channel Key Features

• C-shaped cross-section design: Open on one side, with a web connecting two parallel flanges, providing

  a high strength-to-weight ratio and good bending resistance.

• Material and Coating: Commonly made of carbon steel (Q235/Q355), with surface treatments such as

  hot-dip galvanizing (HDG), zinc plating (ZP), or painting for corrosion resistance; stainless steel (SS) is

  also available.

• Strength and Rigidity: High bending modulus, suitable for bearing vertical loads; standards comply with

  EN 10346, ASTM A653, or GB/T 2518.

• Diverse Specifications: Height 50-400mm, width 30-100mm, thickness 1.5-6mm, length 6m or customized,

  supporting light-lipped or heavy-duty types.

• Advantages: Lightweight, economical, easy to process (drilling, welding), and quick to install, commonly

  used in support systems.

Working Principle

• Load Bearing: The flanges bear compressive/tensile forces, and the web resists shear and bending.

• Structural Support: The open side facilitates the connection of bolts, clamps, or nesting with other

  components to form a framework.

• Rigidity Distribution: The C-shape provides a high moment of inertia, resisting bending deformation;

  the coating protects against corrosion.

• Installation and Fixing: Fixed to the structure with beam clamps or bolts; the principle involves beam

  theory and mechanical interlocking.

Product Applications

• Construction Engineering: Purlins, wall beams, or roof supports; lightweight C-steel is suitable for

  cold forming.

• Steel Structures: Factory buildings, warehouses, or bridge frames, providing secondary beam support.

• Pipes and Cables: Used with beam clamps to fix pipe supports or cable trays.

• Solar Energy Systems: Main beams for photovoltaic brackets; galvanized versions are durable for

  outdoor use.

• Industrial Equipment: Machine frames or conveyor line supports, economical and durable.
