Supplier's note

1. Technical Breakthroughs:

   • SS490 Grade: The Pro model’s 490 MPa yield strength exceeds industry benchmarks by 30%, enabling use in ultra-heavy load scenarios like bridge supports.
   • Thick-Wall Design: The Pro’s 12mm walls provide 50% greater load capacity than standard tubes, ideal for offshore platforms.
   • Dual Galvanization: Advanced/Pro models feature a 2-layer coating, reducing corrosion rates by 25% in marine environments.

2. Optimal Version Selection:

   • Base Model: Suitable for general construction (e.g., residential scaffolding) where cost-efficiency is prioritized.
   • Advanced Model: Ideal for industrial machinery (e.g., crane booms) requiring enhanced durability and moderate load capacities.
   • Pro Model: Tailored for extreme applications (e.g., offshore drilling rigs) needing maximum strength and corrosion resistance.

*Pro Model’s yield strength meets/exceeds JIS standards for high-strength structural steel.
