Which steel rolling process is used to make full-frame rails?

The hot rolling process is commonly used to create full-frame rails due to its ability to manipulate steel at high temperatures, making it easier to form complex shapes with robust structural integrity. During hot rolling, steel is heated above its recrystallization temperature, which allows for significant deformation and shaping without requiring excessive force. This process results in a product that can withstand the harsh conditions and stresses that full-frame rails experience in a vehicle’s construction, such as impact and load bearing.

This method enhances the overall properties of the steel, such as ductility and toughness, making it suitable for the demanding applications found in automotive frames. Additionally, the hot rolling process allows for a smoother finish and better surface properties compared to other methods, which helps improve the joinability and compatibility with other vehicle components during the assembly process.
