2000 * 3000mm size S355ML beam with low price

The company adopts the S355ML beam international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety S355ML beam management system, and has realized the comprehensive integration of the three systems.

After extrusion, the S355ML beam tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.

For Q345B steel plate, Q stands for the yield of Q345B material. The 345 at the back refers to the yield value of Q345B material, which is about 345MPa. The yield value will decrease with the increase of Q345B steel plate thickness. Q345B steel plate has good comprehensive performance, low temperature performance, cold stamping performance, welding performance and machinability. It S355ML beam is widely used in bridges, vehicles, ships, buildings, pressure vessels, etc.

On the whole, on the one hand, under the support of better macroeconomic expectations and high costs, macro funds have disturbed the futures market from time to time and promoted the phased rise of S355ML beam prices. On the other hand, the current steel market's actual demand performance is average, and once S355ML beam prices rise too quickly, there will be fear of heights. In the short term, S355ML beam prices may fluctuate strongly.
