Our company was founded in 2000, which initially committed to providing high-quality steel A283 grade C mild steel coil products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export A283 grade C mild steel coil steel to the international market, opening up the international steel market.
Our company's logistics breaks through the perspective that the center of transportation service is ability, and emphasizes that the purpose of transportation service is customer first. Customer demand determines the content and mode of transportation service, while production is often small batch, diversified and consumer demand tends to be diversified. In the case of personalization, our logistics service also provides personalized service projects.
Rolling steel is the process of pressing to change the shape of the ingot and billet between the rotating rolls. The so-called steel rolling process is a combination of a series of steel rolling processes. The entire rolling production process is always composed of the following A283 grade C mild steel coil basic processes: ① billet preparation:Including the cleaning of surface defects, the removal of surface scale and the pre-heat treatment of billets. ② billet heating ③ steel rolling: it is the core of the entire rolling production process. ④ Finishing.
We supply 3500 tons SA387GR5CL1 steel plates to Pakistan. The main businesses of the Pakistan customer are manufacturing columns & towers, heat exchanger, waste heat recovery boiler, pressure vessel & reactors, tanks, etc. We arranged SGS test for the SA387GR5CL1 steel plates. The test contents include chemical composition analysis, tensile test, impact test, etc. The test results are satisfied. The Pakistan customer gave good feedback after receiving the SA387GR5CL1 steel plates.
