In April 2018, our Philiphine customer purchased 1008 Tons API5L Gr.B ERW&Q345B SMLS pipe for offshore oil field resources drilling project. This is a regular demand almost two month, and we has been cooperated more than three times, totally around 2100 tons steel pipe since 2015 year.
Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s GL-F40 ship building vessel steel domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.
