Rolled steel can be categorized into different types based on processing methods, product shapes, and specific requirements. These primarily include the following:
1. Hot-Rolled Steel Plate
Hot-rolled steel plate is a steel product produced by rolling a billet at high temperatures. Hot-rolled steel plate exhibits excellent weldability, ductility, and toughness, and is widely used in construction, shipbuilding, machinery, and automotive applications.
2. Cold-Rolled Steel Plate
Cold-rolled steel plate is a steel product produced by rolling a hot-rolled billet at room temperature. It boasts a smooth surface, excellent dimensional accuracy, and surface quality, and is commonly used in automotive, electrical, and construction applications.
3. Shaped Steel
Shaped steel is a steel product produced by rolling a billet into various shapes. It primarily includes angles, I-beams, and channels. Shaped steel exhibits excellent strength, rigidity, and wear resistance, and is widely used in construction, engineering machinery, bridges, and other fields.
4. Steel Pipes
Steel pipes are products made from steel through multiple processing steps. They primarily include welded pipes, cold-drawn pipes, and seamless pipes. Steel pipes offer high strength, corrosion resistance, and compressive strength, making them widely used in the petrochemical, shipbuilding, energy, and construction industries.
5. Steel Plate and Strip
Steel plate and strip refers to thin, sheet-like products made from steel sheets or strips through a series of processing steps. Steel plate and strip are widely used in the automotive, electrical appliance, and steel industries.
