Supplier's note

  1. Technical Breakthroughs:

    • ERW Welding: Achieves seamless joints, reducing leakage risks in hydraulic/fluid systems.
    • Galvanized Coating: Offers 30% better corrosion resistance than uncoated steel in marine environments.
    • API Compliance (Pro Model): Meets stringent industry standards for oil/gas drilling applications.

  2. Version Selection Guide:

    • Base Model (Q195): Ideal for light construction (e.g., residential frameworks) where cost-efficiency is prioritized.
    • Advanced Model (Q215): Suitable for medium-load applications (e.g., industrial machinery supports) requiring enhanced durability.
    • Pro Model (Q235): Best for heavy-duty scenarios (e.g., offshore drilling rigs) needing API compliance and extreme strength.

With the Pro Model’s API certification, you can safely handle high-pressure oil pipelines. Pair its galvanized surface with the ERW weld integrity to ensure zero leakage in corrosive chemical environments.
