4 legged self-support steel lattice tower is generally made of angular steel plates and flat steel plates. The 4-leg lattice tower is generally divided into several sections and the sections are connected by flat connecting plates with bolts and nuts. Each tower section is made of angle steelt plates and flat plates. All the steel plates are prefabricated with cutout, holes and hot dip galvanization.
Q355B And EN10025
Why is it in line with the European standard?
Compared with the European standard EN10025, it is known that not only the brand names are similar, but also the chemical composition and mechanical properties are similar. For example, the first element C, the old national standard B level is less than or equal to 0.20, and the same as the European standard JR level. 0.24, of course, this is only one of the reasons. There are other aspects and performances that are almost identical to the European standard. In other words, the largest quantity of S355 in the conventional trade, the national standard and the European standard can already be equal.
Q355B Equivalent To S355
In terms of use: CEIBS has cooperated frequently in many fields in recent years. Many projects have come to purchase steel in China, and different standards will cause a lot of trouble. For example, the purchase of S355JR steel, most of which must be ordered from steel mill, and after the implementation of the new national standard The S355JR can be directly replaced with the Q355B. It can be said that the zero difference is docked, as long as the design strategy is slightly changed.
Future Of Q355B Steel
Production: Although the demand for European standard products has gradually increased in recent years, due to different standard systems, different composition properties, production organization and its inconvenience, resulting in increased production costs, and after this change, S355JR and Q355B can almost judge each other. For the plate, it is basically to change the warranty book. Unlike the previous two brands, it is impossible to judge each other. If the S355 stream is single, it can only be used when it is available, and the price will be much lower. The Q345 series is also different from other aspects of the European change. The European standard order can only be regenerated, and the new national standard is not only the B-level intercommunication, but also several other levels, such as S355J0, J2, etc.
