Q275FTD Wind Power Steel

GB/T 28410-2012 | High Strength Wind Tower Plate | -20°C Impact (47J)

📏 Standard: GB/T 28410-2012
🏗️ Wind Power Towers
❄️ -20°C Impact 47J (Grade D)
💪 Yield ≥275 MPa

Product Overview

Q275FTD is a high-strength structural steel plate manufactured in accordance with GB/T 28410-2012, specifically designed for wind turbine tower construction requiring enhanced load-bearing capacity and low-temperature toughness. This grade provides higher yield strength (275 MPa) compared to Q235 series, excellent weldability, and guaranteed impact properties at -20°C, making it ideal for wind power installations in cold climate regions requiring superior strength-to-weight ratio.

Key Advantages

  • Higher Strength Grade: Minimum yield 275 MPa (≤16mm) for lighter tower designs.
  • Guaranteed -20°C Impact Toughness: Minimum 47J at -20°C (Grade D) – ideal for cold climates.
  • 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.

Frequently Asked Questions

What is the advantage of Q275FTD over Q235FTD?

Q275FTD offers higher minimum yield strength (275 MPa vs 235 MPa) while maintaining the same -20°C impact toughness (47J), allowing for lighter and more efficient tower designs in cold regions.

Is Q275FTD suitable for onshore wind in cold climates?

Yes, its guaranteed -20°C impact energy (47J) makes it ideal for onshore wind farms in cold temperate zones where winter temperatures can drop to -20°C.
