Q235FTE Wind Power Steel
GB/T 28410-2012 | Arctic-grade Wind Tower Plate | -40°C Impact
Product Overview
Q235FTE is a specialized structural steel plate manufactured in accordance with GB/T 28410-2012, specifically designed for wind turbine tower construction requiring superior low-temperature toughness. This grade provides optimal strength, excellent weldability, and guaranteed impact properties at -40°C, making it ideal for wind power installations in extremely cold climate regions such as high-altitude or subarctic environments.
Key Advantages
- Guaranteed -40°C Impact Toughness: Minimum 34J at -40°C (Grade E), designed for arctic conditions.
- Optimized Weldability: Low carbon (C≤0.18) and controlled alloying elements.
- Strict Quality Control: Full traceability with EN 10204 3.1/3.2 certification.
- Versatile Availability: Plates up to 100mm thick, coils available.

Frequently Asked Questions
What is the difference between Q235FTE and Q235FTD?
FTE guarantees impact toughness at -40°C (34J), while FTD guarantees at -20°C (47J). FTE is specifically designed for arctic, subarctic, or high-altitude wind farms where temperatures can drop below -40°C.
Is Q235FTE suitable for offshore wind in northern seas?
Yes, its -40°C toughness makes it ideal for North Sea, Baltic Sea, and other cold offshore environments. For extreme Arctic offshore, consider Q235FTF (-50°C).
MOQ?
25MT for plates, 50MT for coils. Flexible for trial orders.
Third-party inspection?
SGS, BV, TÜV available upon request.
