In automobile manufacturing, the largest number of cold-drawn profiles are used for trucks and large passenger cars. They are mainly used to make carriage frames, wallboards, floor panels, body frames, bottom beams and door and window frames. The situation of medium bus is similar to that of large bus. Small cars use many kinds of specifications, and most of the cross-sections are more complex, size accuracy requirements are stringent.
For heavy trucks (including light trucks), the number of cold-drawn profiles used in the carriage is the largest. According to different models, the structure of the car is different. For example, the wallboard and the frame of the carriage of some models are integral and the components are of the same thickness, while the wallboard and the frame of the carriage of some models are separate components, and the thickness of the two components is different.

Due to the harsh working environment of the ship, the hull shell is subject to chemical corrosion of seawater, electrochemical corrosion and corrosion of marine organisms and microorganisms; the hull is subjected to large wind and wave impacts and alternating loads; the shape of the ship is complicated by processing methods, etc. Steel for hull structure is strictly required. First, good toughness is the most critical requirement. In addition, high strength, good corrosion resistance, weldability, processability and surface quality are required. Our products are well suited to meet the above requirements.
