Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Structural Support: Designed for load-bearing applications in construction and infrastructure, featuring high-strength steel grades (Q195-Q345) and ERW (Electric Resistance Welded) technology for seamless joints.
  • Corrosion Resistance: Hot-dipped galvanized surface ensures durability in outdoor and corrosive environments, extending service life in harsh conditions.

Key features

  • 1. Corrosion-Resistant Hot-Dip Galvanized Steel

    • With a zinc-coated galvanized surface, protect against rust and corrosion in outdoor or industrial environments. Outperforms uncoated steel pipes in longevity and durability*.

  • 2. Precision-Engineered ERW Construction

    • With Electric Resistance Welded (ERW) technology and ±1% tolerance, ensure structural integrity for high-pressure or load-bearing applications. Achieve tighter fits than non-ERW pipes*.

  • 3. CE & International Standard Compliance

    • With CE certification and adherence to ASTM, AISI, and JIS standards, meet global safety and quality requirements. Trusted for commercial and industrial use over non-certified alternatives*.

  • 4. Versatile Application & Customization

    • With EMT, API, and thick-wall variants, adapt to plumbing, construction, or oil industry needs. Customize lengths and shapes via punching, cutting, and bending services for tailored solutions*.

  • 5. High-Strength Steel Grades for Durability

    • With Q345/Q235 steel grades, deliver superior tensile strength for heavy-duty use. Outperform lower-grade materials in harsh or dynamic conditions*.

Supplier's note

  1. Technical Breakthroughs:

    • Galvanized Coating: Triple the corrosion resistance of uncoated steel, extending lifespan in marine or chemical environments.
    • ERW Welding: Seamless joints reduce leakage risk by 30% compared to traditional welded pipes.
    • Precision Tolerance: ±1% accuracy ensures compatibility with automated machinery.

  2. Version Selection Guide:

    • Base Model: Ideal for standard construction (e.g., residential framing) where cost efficiency is prioritized.
    • Advanced Model: Suitable for heavy industrial use (e.g., oil rigs) requiring higher pressure resistance.
    • Pro Model: Engineered for extreme conditions (e.g., offshore platforms) with corrosion resistance exceeding industry benchmarks by 40%.

*Pro Model available upon request for specialized projects.
