1200 tons S690QL steel plate spec pickling steel coil to Columbia

The company has a solid economic foundation, a strong network of relationships, complete technology and staffing. With my country’s entry into the WTO, the import and export trade is increasing day by day. In order to further meet the needs of S690QL steel plate spec traders and importers and exporters, our company carefully builds for merchants One-stop service from door to door. We have a complete import and export service system in Mainland China, and S690QL steel plate spec have established close cooperative relations with many shipping companies and airlines.

After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the S690QL steel plate spec plate should be derusted before cutting.

In the past 10 years, domestically-made offshore platform steel has been widely adopted in China's offshore oil projects, and offshore platform steel has gradually developed in the direction of high strength. Relevant data show that the pile legs, pile boots, cantilever beams and other key parts of the jack-up platform require high load. In order to improve the stability of the hull during towing after floating, it needs to be lightweight, and high-strength steel plates must be used.
