Q690D steel is a low-alloy, high-strength structural steel widely used in bridge engineering, heavy machinery manufacturing, construction machinery, wind power equipment manufacturing, and other fields. It is mainly available in hot-rolled and cold-rolled sheets. Length and thickness can be customized according to customer requirements.
Product advantages
1. Excellent mechanical properties: The bearing capacity is more than 80% higher than that of ordinary steel.
2. Low temperature toughness: Ensures structural safety in extremely cold environments.
3. Good weldability
Application scope of Q690D high-strength structural steel plate
1. In the field of bridge construction, it can be used to manufacture key load-bearing structural parts such as the main beam and piers of large bridges.
2. In heavy machinery manufacturing, it is often used to produce high-strength components such as the frame and boom of mining machinery and the boom of port cranes.
3. In construction machinery, it is suitable for manufacturing important structural components such as excavator booms and dipper arms and loader frames.
4. In wind power equipment manufacturing, it can also be used to manufacture components such as wind turbine towers.
