Hot-rolled steel is a steel that has been heated and rolled at high temperature. Its strength is not very high, but it is sufficient for our use. Its plasticity and weldability are better, so we often use it; cold-rolled steel is ordinary hot-rolled steel. The steel that has been drawn by force and exceeds the strain hardening stage has high strength, but poor toughness and weldability, and is relatively hard and brittle. Hot rolling is processed at high temperature. Hot rolling means that the material needs to be heated during or before rolling steel. Generally, it is heated above the recrystallization temperature before rolling.
Carbon steel, also known as carbon steel, is an iron carbon alloy with an internal carbon content of nearly 2%. In addition to carbon, carbon steel contains many other elements, such as manganese, sulfur, or silicon. Generally speaking, the higher the amount of carbon contained in carbon steel, the greater its hardness, the higher the strength will be produced. Just note that the higher the carbon content, the lower the plasticity.

Cold-rolled steel is steel produced by cold rolling. Cold rolling is a steel plate in which the steel plate is further thinned to a target thickness at room temperature. Compared with hot-rolled steel sheets, the thickness of cold-rolled steel sheets is more accurate, and the surface is smooth and beautiful, and it also has various superior mechanical properties, especially in terms of processing performance. Because cold-rolled raw coils are relatively brittle and hard, they are not suitable for processing, so cold-rolled steel sheets usually require annealing, pickling and surface smoothing before being delivered to customers. The maximum thickness of cold rolling is below 0.1--8.0MM. For example, the thickness of cold-rolled steel sheets in most factories is below 4.5MM; the minimum thickness and width are determined according to the equipment capacity of each factory and market demand.

A steel bar is a strip of steel, a type of building material. For example, in reinforced concrete, the skeleton used to support the structure. Steel bars are tensile but not compressive, concrete is compressive but not tensile, the combination of the two has good mechanical strength, the steel is protected by the concrete and will not rust, and the thermal expansion coefficient of the steel and concrete is approximately the same, and it will not produce rust. Corrosion due to cracks, so it has become an ideal material for modern buildings, and has become a widely used reinforced concrete building.
