Various types of Chinese wind power steel grades, this product is suitable for wind power generation towers and other scenarios.
- Wind power generation: This is the most important application scenario. This type of steel plate is specially designed to withstand the special environmental conditions and wind force that wind power generation towers face, and has high and toughness.
- Bridge construction: Due to its excellent mechanical properties, including high strength and toughness, this type of steel plate is also suitable for bridge construction.
- High-rise buildings: In high-rise buildings, especially in structures that need to withstand large loads and complex stress environments, this type of steel plate is also used.
- Power transmission tower: In addition to wind power generation towers, this type of steel plate is also suitable for other types of power transmission towers.
- Other engineering projects requiring high-strength structural steel: For example, some structural engineering projects that require special strength and toughness may also use this type of steel plate.
