Product Description

2) Excellent Load-bearing Capacity
3) Outstanding Adaptability
4) Adjustability and Flexibility
5) Environmental Protection and Reusability
2. Q345 Low-Alloy High-Strength Structural Steel: Compared with Q235 steel, Q345 steel has higher strength and better comprehensive mechanical properties. It is suitable for engineering projects with higher requirements for load-bearing capacity, such as industrial plants, large billboards, and wind turbine foundations. It can also be subjected to hot-dip galvanizing or other anti-corrosion treatments to enhance its corrosion resistance in harsh environments.
