41×21 Pre-Galvanized Serrated (Flowered) Square-Edge C Strut Channel, Full Complete Size Series Available

41×21 square corner serrated C steel is a standardized cold roll formed structural profile developed for lightweight construction frameworks, featuring 41mm web height and 21mm flange width. Different from conventional rounded corner C channel, this product adopts precise square-edge forming technology with inner serrated flowered anti-slip teeth. It is manufactured from premium Q235B / Q355B hot rolled steel strips via professional cold bending processes and fully complies with GB/T 6728-2017 national cold-formed steel specification.

This strut is widely deployed in all kinds of light-duty structural engineering. Standard wall thickness covers 1.2mm to 2.5mm, and custom cut lengths from 4m up to 12m are supported. It adopts pre-galvanized surface finish, which delivers exceptional rust and corrosion resistance, making it ideal for outdoor projects and high-humidity harsh working conditions.

Thanks to square-edge molding, connecting fittings fit tightly with zero gaps without extra grinding work during assembly. The inner serrated flowered teeth increase friction between bolts and the channel body, effectively preventing fastener sliding and loosening caused by long-term static load and equipment vibration. On-site processing is highly flexible; users can cut, punch holes and fasten components with bolts directly.

The product owns four core competitive strengths:

• Unique square edge design: tidy right-angle edges ensure uniform force distribution and superior matching accuracy for projects demanding high alignment precision;
• Inner serrated flowered structure: anti-slip teeth enhance bolt clamping force, prevent loosening under vibration, and improve overall shear resistance of the support system;
• Light weight yet high rigidity: low self-weight paired with optimized sectional inertia delivers strong anti-bending and anti-torsion capacity to satisfy lightweight load-bearing standards;
• Long service life with corrosion resistance: pre-galvanized surface treatment effectively slows down oxidation and extends service cycles;
• Outstanding cost performance: high-precision production boosts raw material utilization and cuts secondary processing expenditure, with universal compatibility for solar support racks, mechanical equipment frames and building partition keels.

Integrating practicality and wide adaptability, this square-edge serrated C strut acts as an efficient, long-lasting preferred structural material for lightweight construction, perfectly matching all refined installation standards.
