Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, S550MC steel based on a high starting point and high technology, the company has vigorously developed various steel products S550MC steel and deep-processed parts, steel structures, precision castings, seamless pipes.

With the development of multimodal transport in the international shipping market and the increase of the complexity of the integrated transport chain, modern ports, as the intersection of the three transportation modes of sea, land and air, are developing from traditional transfer and product distribution functions to all-round value-added services, becoming the central link connecting the world's production, exchange, distribution and consumption, and supporting the world economy and international trade An important part of the developed international circulation system.

There is an inherent difference between the cold forming properties of low-alloy high-strength steel and carbon structural steel. First of all, a certain amount of permanent deformation of low-alloy high-strength steel requires greater force than S550MC steel, carbon structural steel of the same size. Second, when low-alloy high-strength steel is formed, a slightly larger allowable amount for springback should be given. According to experience, unless the low-alloy high-strength steel is processed to control the shape of inclusions, it is necessary to use a larger bending radius than carbon structural steel during cold forming.

The Indonesia INKA is the only train carriage maker for railway industry in Indonesia. We cooperated with them since 2012 and supply them SPA-H steel. The SPA-H steel is used by them to fabricate train carriage. We have huge stocks for SPA-H steel and can arrange delivery for them in short time after receiving order. Meanwhile, our product S550MC steel quality has passed their test for so many times use. Therefore, they trust us and give us repeat orders regularly. And we also do our best to support them and have never let them down though past cooperations.
