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. It is also utilized for solar photovoltaic mounting systems.

FAQ
1. 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.
2. 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.
3. 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.
4. 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.
5. Can C-channel steel be used for solar panel mounting?
Yes, it is widely used in solar PV mounting systems for ground and rooftop installations due to its strength and modular design.
