Product Description

41×21 Square Edge C Strut Channel, Full Complete Size Series Available

Product Overview

41×21 square corner 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. 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. Multiple surface finishing options are available: hot dip galvanizing, electro galvanization or raw black steel finish. Galvanized variants deliver exceptional rust and corrosion resistance, making them 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. 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;
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: mature surface treatment techniques effectively slow down oxidation and extend 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 C strut acts as an efficient, long-lasting preferred structural material for lightweight construction, perfectly matching all refined installation standards.

Core Product Advantages

This square edge 41×21 C strut comes with outstanding comprehensive performance suitable for diverse engineering applications:

Powerful anti-rust and anti-corrosion performance: Dense, even galvanized zinc layer blocks erosion caused by moisture and air. No extra anti-corrosion coating is required, allowing long-term service outdoors and in damp corrosive environments to prolong the profile’s service life.
Rapid, trouble-free field assembly: Pre-punched holes can be customized with exclusive aperture sizes and hole spacing to fit bolt connection and pipeline penetration directly. On-site secondary drilling is eliminated, drastically cutting construction periods and labor costs.
Stable load-bearing structural performance: Despite its lightweight design, optimized section inertia provides reliable bending and torsion resistance, meeting lightweight load demands steadily while lowering the overall dead load of the whole structure and foundation pressure.
Strong universality & flexible adaptability: Widely applicable to solar mounting frames, equipment support brackets and building keel systems. High dimensional precision and regular shape, customizable wall thickness (1.2–2.5mm) and total length (4–12m) balance practical performance and economic cost perfectly.
