Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for grade P235GH steel material and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.

We have gradually formed four advantageous products of steel plate, steel pipe, grade p235gh steel material, stainless steel and special steel, and established our own processing center to meet the diversified needs of customers. At the same time, we also set up professional environmental protection, baby carriage and other projects. With the professional team and strong background of steel plate, steel pipe, stainless steel and special steel, it will drive the rapid development of other projects.

Rizhao Steel 5#ESP Headless Strip Production Line Project is a key construction project in Shandong Province. It is also the fifth domestic ESP production line introduced by Rizhao Steel and the sixth ESP production line in the world. Its thinnest design is 0.5mm, which is at the world's leading level. The more than 20 important nodes set by the entire project have been basically completed, and the equipment has entered the commissioning stage. It is expected to be put into operation at the end of November.
