Q275FTF Wind Power Steel

GB/T 28410-2012 | High Strength Wind Tower Plate | -50°C Impact (34J)

📏 Standard: GB/T 28410-2012
🏗️ Wind Power Towers
❄️ -50°C Impact 34J (Grade F)
💪 Yield ≥275 MPa

Product Overview

Q275FTF is a high-strength structural steel plate manufactured in accordance with GB/T 28410-2012, specifically designed for wind turbine tower construction requiring superior load-bearing capacity and extreme low-temperature toughness. This grade provides higher yield strength (275 MPa) compared to Q235 series, excellent weldability, and guaranteed impact properties at -50°C, making it ideal for wind power installations in arctic, Antarctic, and severe cold climate regions requiring exceptional strength-to-weight ratio and ultimate cold resistance.

Key Advantages

  • Highest Strength Grade: Minimum yield 275 MPa (≤16mm) for lighter tower designs.
  • Guaranteed -50°C Impact Toughness: Minimum 34J at -50°C (Grade F) – ultimate cold resistance.
  • Optimized Weldability: Low carbon (C≤0.18) and micro-alloying elements.
  • Strict Quality Control: Full traceability with EN 10204 3.1/3.2 certification.
  • Versatile Availability: Plates up to 100mm thick, coils upon request.
