Q345RZ35 steel plate, as a high-end pressure vessel plate compliant with the Chinese national standard GB/T 713-2014, derives its core competitive advantage from its Z35 grade thickness-directional performance (Z-directional property).
This characteristic ensures the steel plate resists lamellar tearing under high pressure, making it particularly suitable for critical equipment manufacturing with stringent safety requirements, such as pressure vessels and boiler drums.
Q345RZ35 steel plate provides reliable safety guarantees in high-risk environments including petroleum, chemical plants, and power stations.
Our production line can roll finished steel plates with a maximum width of 5,350 mm, covering thicknesses from 6 mm to 300 mm, achieving full-range production capabilities for 'ultra-wide, ultra-narrow, ultra-thin, and ultra-thick' specifications. This 'versatile' manufacturing strength enables China to independently supply high-end applications such as large pressure vessels and bridge steel structures for the first time. This breakthrough precisely aligns with the transformation of China's steel industry from 'scale expansion' to 'quality improvement.
