Steel coils are processed and shaped into various products through a series of manufacturing processes. First, the steel coil is uncoiled and cleaned to remove any impurities. Then, it goes through a process called leveling, where the coil is flattened and straightened. Next, the steel is cut into the desired length or shape, using techniques like shearing or slitting. After that, it may undergo additional processes such as forming, bending, or rolling to give it the desired shape. Finally, the steel is often treated with coatings or finishes to enhance its durability and appearance.
