Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Structural Support: Designed as C-shaped purlins (U-channel profiles) for roofing, wall framing, and load-bearing applications. The Q235 steel material ensures high strength and durability, supporting heavy loads in both commercial and home use.
  • Multi-Configuration Options: Available in perforated and plain types for diverse needs, such as drainage in roofing systems (perforated) or solid structural support (plain). Customizable via bending, cutting, welding, and punching to fit specific project requirements.

Key features

  • 1. Durable Q235 Steel Construction

    • With Q235 steel material, achieve robust structural integrity and superior load-bearing capacity compared to lower-grade steels*. The non-alloy composition ensures reliability in harsh environments, making it ideal for long-term use in construction and industrial applications.

  • 2. Customizable C-Channel Design

    • With a versatile C-channel shape and perforated/plain options, easily adapt to diverse project needs. On-demand processing services (bending, cutting, welding) enable 2x faster customization compared to rigid, pre-fabricated alternatives*.

  • 3. Precision-Engineered Dimensions

    • With a length range of 100-1200cm and ±1% tolerance, ensure seamless integration into large-scale projects without costly adjustments. This precision outperforms models with looser tolerances, reducing installation errors by up to 30%*.

  • 4. Multi-Scenario Versatility

    • With adaptability for construction, automotive, and manufacturing applications, deploy in both commercial and industrial settings. The perforated design enhances airflow in roofing systems, unlike plain profiles limited to structural roles*.

  • 5. AISA Standard Compliance

    • With AISA certification, meet internationally recognized quality and safety benchmarks that 90% of competitors fail to achieve*. This ensures compatibility with global construction codes and reduces compliance risks.

Product details

c Purlins Sizes and Weights 6 Inch Black Iron Purlingi c Purlin Specification

Supplier's note

  1. Technical Breakthroughs:

    • AISI Compliance: Ensures compatibility with global construction codes.
    • 1% Tolerance: Reduces fitting errors by 30% compared to industry averages.
    • Hot-Dip Galvanization (Advanced/Pro): Doubles corrosion resistance in marine environments.

  2. Version Selection Guide:

    • Base Model: Ideal for standard residential or light commercial roofing where cost-efficiency is prioritized.
    • Advanced Model: Suitable for agricultural or industrial settings needing perforations for drainage or ventilation.
    • Pro Model: Best for heavy-duty applications like warehouses or offshore platforms, where extreme load and corrosion resistance are critical.

With the Pro Model’s 800kg/m² capacity, you can support heavy machinery without compromising safety. Pair its zinc-aluminum coating with perforated surfaces to manage moisture in humid climates, extending lifespan by 50%.
