Q275FTC Wind Power Steel

GB/T 28410-2012 | High Strength Wind Tower Plate | 0°C Impact (47J)

📏 Standard: GB/T 28410-2012
🏗️ Wind Power Towers
🌡️ 0°C Impact 47J (Grade C)
💪 Yield ≥275 MPa

Product Overview

Q275FTC 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 reliable toughness. This grade provides higher yield strength (275 MPa) compared to Q235 series, excellent weldability, and guaranteed impact properties at 0°C, making it suitable for wind power installations requiring superior strength-to-weight ratio.

Key Advantages

  • Higher Strength Grade: Minimum yield 275 MPa (≤16mm) for lighter tower designs.
  • Guaranteed 0°C Impact Toughness: Minimum 47J at 0°C (Grade C) – ideal for moderate 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 Q275FTC over Q235FTC?

Q275FTC offers higher minimum yield strength (275 MPa vs 235 MPa), allowing for lighter tower designs or higher load capacity while maintaining 0°C impact toughness (47J).

Is Q275FTC suitable for onshore wind in temperate climates?

Yes, its 0°C impact energy (47J) makes it ideal for most onshore wind farms where minimum operating temperatures stay above -20°C. For colder regions consider D, E, or F grades.
