q345r standard properties

Common grades of carbon structural steel plates: A36, A283Grade C, A572Grade 60, A573Grade 70, Q235B, Q235C, S235JR, S275J0, SS400, St37-2, q345r standard, St52-3. Our company can provide carbon structural steel plate thickness ranging from 6 to 300mm. These plates are widely used in various types of engineering structures such as steel structure buildings, construction machinery, heavy vehicles, bridges, pressure vessels. Besides, we can provide Q235B carbon steel plate with Z direction test.

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 q345r standard steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge q345r standard 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.

We do sand blasting and shop primer for various q345r standard steel plates such as carbon steel plates, high strength low alloy steel plates, shipbuilding steel plates, etc. before delivery, so as to protect the steel plates from going rust during transportation. Our sand blasting standard is SA2.5, and shop primer q345r standard thickness is 20μm or so. Our shop primer has been certified by ABS, LR, BV etc. authorities.

When phosphorus, copper, chromium, nickel and other trace elements are added to the weathering steel sheet, a dense and strong adhesion protective film will be formed on the steel surface, which will hinder the corrosion from spreading and developing inside, and protect the substrate under the rust layer, so as to slow down the corrosion rate. That is why the weathering steel sheet, q345r standard has good atmosphere corrosion resistance.

The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
