Low alloy high strength structural steel is a kind of steel which contains a small amount of alloy elements and is mainly used in construction and engineering structures. Main Chinese steel grades of low alloy high strength structural steel are: Q345A, Q345B, Q345C, Q345D, Q345E, Q390A, Q390B, Q390C, Q390D, Q390E, Q420A, Q420B, Q420C, Q420D, Q420E, Q460C, Q460E, Q500C, Q500D, Q500E, Q550C, Q550D, Q500D, Q620E, Q690C, Q690E, EN10025-4 steel plate.

The hot rolling method is to heat the EN10025-4 steel plate steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of EN10025-4 steel plate rolling process is usually called semi-finished product production, also called blank production.

As we all know, steel pipes occupy more space in the process of transportation. If there is no good way of packing, the transportation cost for steel pipes will be a big expense. In view of this characteristic, our company is ingenious and adopts the nest package method to solve this problem perfectly. The premise of the nest package is that the diameters of the steel pipes are different, and the small diameter pipe is inserted in the large diameter pipe. This not only saves the volume, but also saves the transportation cost. It also reduces the loading and unloading workload by half, saves precious time, and enables customers to receive goods earlier.

Keep close relationship with all manufacturers and users, cooperate sincerely, share weal and woe together. We are deeply tolerant of travelling with you! We value and value each other's career and friendship. No matter when and where, all our staff will spare no effort to put into the work, and do their best to provide EN10025-4 steel plate satisfactory services for all friends, so as to achieve win-win and multi win for each other.
