Introduction to open plate

     The open plate is a steel plate with a certain thickness and width rolled according to the user's requirements. The original flat plate is rolled into the size required by the national standard when the steel factory leaves the factory. Generally, the original flat plate has strict size, good performance and high price. The flat panel is relatively cheap, and the size is slightly different.

      It is a more colloquial name. In gb709 being revised, the flat plate and the original flat plate should be called shear steel plate and single rolled steel plate respectively. When the steel plate comes out of the steel plant, it is rolled. The flat plate after these steel plates are leveled by the machine is called "flat plate". Just like the whole roll of toilet paper, the internal stress level of the flat plate is high, so the dimensional stability is poor. With the different process parameters during leveling operation, the internal stress distribution is also different, and the bearing capacity will be different in different directions of vertical length, and this bearing capacity is difficult to be measured by general strength index. Therefore, the open plate will have great welding deformation during welding, which is difficult to adjust. Therefore, the parts with high requirements for appearance quality cannot use the flat plate.

The thickness of the split plate is 1.5-20mm, and the materials are Q235 and q355. It is mainly used on non pressurized containers and storage tanks.
