Products Description
C-channel is a type of steel that is automatically processed and formed by a C-shaped steel forming machine. It has the characteristics of thin wall, light weight, excellent cross-sectional performance, and high strength. Its production process includes hot rolled plate cold bending processing. It has a wide range of applicability in the construction field. It is often used as purlins and wall beams in steel structure buildings. At the same time, it can be flexibly combined into lightweight roof trusses, brackets and other building components. In the field of mechanical manufacturing, C-channel is often used to manufacture components such as columns, beams and arms. In addition, C-channel is also used in the fields of automobile manufacturing, shipbuilding, etc. to make shells, chassis, etc.

FAQ
1. What is C-channel steel used for?
C-channel steel is mainly used for structural support systems such as solar mounting structures, cable trays, wall framing, HVAC support, and industrial racking systems.
2. What is C-channel steel made of?
It is typically made from carbon steel such as Q235, Q355, or ASTM A36, and can be finished with hot-dip galvanizing or ZAM coating for corrosion resistance.
3. What does "C-channel" mean?
"C-channel" refers to the cross-sectional shape of the steel profile, which resembles the letter "C", providing strength and easy installation capability.
4. What are the advantages of C-channel steel?
C-channel steel offers high strength, lightweight structure, easy assembly, cost efficiency, and excellent compatibility with bolts and accessories.
5. Is C-channel steel suitable for outdoor use?
Yes, especially when galvanized or ZAM-coated, it provides strong corrosion resistance for outdoor environments like solar farms and construction sites.
6. What sizes are available for C-channel steel?
Common sizes include 41×21 mm, 41×41 mm, 41×62 mm, and custom dimensions depending on project requirements.
7. What is the difference between slotted and solid C-channel?
Slotted C-channel has oval holes for easy installation and adjustment, while solid C-channel has no holes and provides higher structural rigidity.
