Raw material selection: High-quality low-carbon steel (e.g., Q235 steel) is chosen as the primary raw material.
Heating: Steel billets are heated to high temperatures, typically between 1200°C and 1300°C, to ensure material plasticity.
Hot rolling: Heated steel billets are processed through rolling mills to form the desired flat bar shape. During rolling, the steel's grains are rearranged, improving its mechanical properties.
Cooling: Hot-rolled steel is naturally cooled on cooling beds. Cooling rates are controlled to ensure appropriate hardness and toughness.
Cutting and straightening: After cooling, the flat bars are cut to specified lengths and straightened to ensure linearity.
Surface treatment: Depending on customer requirements, A36 hot rolled flat bars may undergo surface treatments such as pickling, oiling, or galvanizing to prevent oxidation and corrosion.

Features of A36 Hot Rolled Carbon Steel Coils
High quality low carbon steel (such as Q235 steel) is selected as the main raw material.
Steel billets are heated to high temperatures, generally between 1200°C and 1300°C, to ensure the plasticity of the material.
The heated steel billets are processed by rolling mills to form the desired flat - bar shape. During the rolling process, the grains of the steel are re - arranged, which improves its mechanical properties.
The hot rolled steel is cooled naturally on cooling beds. The cooling rate is controlled to ensure the appropriate hardness and toughness.
After cooling, the flat bars are cut to the specified lengths and then straightened to ensure straightness.
According to customer requirements, A36 hot rolled flat bars may be subjected to surface treatments like pickling, oiling, or galvanizing to prevent oxidation and corrosion.
