Supplier's note

  1. Technical Breakthroughs:

    • High-Tensile Carbon Steel: Exceeds Aisi standards with 650 MPa tensile strength in the Pro model, enabling use in earthquake-resistant skyscrapers.
    • Precision Threads: The Advanced Model’s ±0.5% tolerance ensures minimal misalignment in modular construction.
    • Ribbed Surface: Enhances bond strength with concrete by 25% compared to smooth bars.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard residential buildings where cost efficiency is prioritized.
    • Advanced Model: Suitable for commercial projects requiring precise load distribution (e.g., bridges).
    • Pro Model: Recommended for extreme environments (e.g., offshore platforms) needing unmatched strength and corrosion resistance.

Example: With the Pro Model’s 650 MPa tensile strength, engineers can safely reinforce columns in high-rise structures, even under seismic stress. Its zinc-plated coating pairs with the ribbed surface to resist corrosion and maintain structural integrity for decades.
