High-Strength Steel Solutions for Offshore & Tall Wind Turbine Projects

Why Choose S420NL and S460NL for Wind Tower Construction?

As wind energy projects scale up in height, power output, and environmental complexity, the demand for high-strength structural steel plates like S420NL and S460NL has significantly increased. These grades offer higher yield strength than S355 series, making them ideal for:

• Offshore wind turbine towers
• Extra tall onshore towers (120m+)
• Heavy-duty transition segments and flange joints

CJM supplies S420NL steel plates for wind tower fabrication with EN 10025-3 certification, ensuring low-temperature performance and excellent weldability for critical wind energy infrastructure.

Applications and Use Cases

S420NL and S460NL are designed for use in:

• Offshore wind farm tower segments
• Base sections requiring higher load-bearing capacity
• Transition flanges and ring stiffeners
• Wind turbine tower reinforcement systems

These plates are often sourced by EPC contractors, wind tower fabricators, and engineering firms who are bidding on or building high-load wind energy projects in Europe, Southeast Asia, and the Americas.
