C-shaped steel

High-Precision Cold-Formed C-Shaped Steel (C-Purlins) for Modern Construction

Our premium C-shaped steel is the definitive solution for lightweight structural framing and roofing systems. As a specialized C-purlin manufacturer, we utilize advanced cold-roll forming technology to produce sections with exceptional dimensional accuracy and a high strength-to-weight ratio. Engineered from high-tensile galvanized or black steel strips, our C-channels are widely used as purlins, girts, and wall studs in industrial warehouses and solar mounting systems. Meeting international standards like ASTM A653 and EN 10346, our C-shaped steel ensures rapid on-site assembly and long-term structural integrity for any architectural project.

    Versatile C-Shaped Steel: The Backbone of High-Efficiency Light Steel Structures

    Engineered for Excellence: The C-Section Advantage

    C-shaped steel, also known as C-purlins or C-channels, is a cold-formed structural member characterized by its unique “C” profile. Unlike hot-rolled beams, C-shaped steel is manufactured by feeding steel coils through a series of rollers at room temperature. This process allows for thinner, lighter sections that maintain remarkable structural rigidity, making them the preferred choice for modern pre-engineered buildings (PEB) and renewable energy infrastructures.

    Technical Specifications & Customization

    Our factory operates high-speed, automated production lines capable of delivering a wide range of specifications tailored to your engineering needs:

    • Material Grades: Q235, Q355 (S355JR), ASTM A653 (Galvanized), and high-strength G450/G550 grades.

    • Web Height (H): 80mm – 300mm

    • Flange Width (B): 40mm – 100mm

    • Lip Length (C): 10mm – 25mm

    • Thickness (T): 1.5mm – 3.5mm

    • Surface Treatment: Pre-galvanized (Z120–Z275 coating), Hot-dipped galvanized, or Black (uncoated) for welding.

    Key Benefits of Our C-Shaped Steel

    • High Strength-to-Weight Ratio: Dramatically reduces the overall weight of the steel structure, leading to significant savings in foundation and transportation costs.

    • Pre-Punched Precision: We offer online automated punching services. Our C-purlins come with pre-drilled holes based on your blueprints, ensuring “plug-and-play” installation on-site.

    • Corrosion Resistance: Our galvanized C-sections offer superior protection against oxidation, making them ideal for outdoor solar plants and coastal industrial zones.

    • Cost-Effective Design: Cold-forming allows for precise lengths (up to 12 meters or more), minimizing material waste and eliminating the need for on-site cutting.

    Comparison: C-Purlin vs. Z-Purlin

    FeatureC-Shaped Steel (C-Purlin)Z-Shaped Steel (Z-Purlin)
    ShapeSymmetrical “C” ProfileAsymmetrical “Z” Profile
    OverlappingCannot be overlappedCan be lapped for continuous spans
    Typical UseSimple spans, wall girts, door framesContinuous spans, heavy roof loads
    InstallationEasier to align and boltRequires more complex nesting

    Primary Applications

    Our C-shaped steel is a versatile component found in numerous sectors:

    1. Industrial Warehousing: Secondary framing for roofs (purlins) and walls (girts).

    2. Solar Mounting Systems: The primary structural rails for ground-mounted and rooftop solar arrays.

    3. Light Steel Villas: Load-bearing wall studs and floor joists for residential steel framing.

    4. Mezzanine Floors: Providing lightweight support for internal storage platforms.
