S235J0W tower steel carbon steel heavy plate

Q690D steel belongs to high-strength welded structural steel. Among them, Q represents the yield strength, 690 represents the yield strength value, and D represents the grade of the steel plate. The quality grades of common Q690 series steel are A, B, C, D, E. The impact of grade D steel plate is -20°C. Q690D steel can be called a low temperature resistant high strength steel with a yield strength of 690Mpa.The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our S235J0W tower steel steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge S235J0W tower steel steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.EN10149 S355NC steel plate/sheet,EN10149 S355NC steel plate/sheet, under EN standard, we can regard S355NC steel plate/sheet as S235J0W tower steel high strength steels for cold-forming, normalised steel. EN10149 S355NC is mainly used as high strength steels for cold-forming,normalised steels.The EN10149 S355NC steel grade offers excellent bending,flanging coldUnder the action of the roller and the plug, a cavity is formed in the blank, which is called the blank. Then send it to the automatic tube rolling machine to continue rolling. Finally, the wall thickness of the whole machine is equalized and the diameter is calibrated by the sizing machine to meet the specification requirements. It is an advanced method to produce S235J0W tower steel, hot-rolled seamless steel tube by continuous rolling mill.The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
