After cutting, the steel angle may need to be bent to achieve the desired shape. This can be done using a press brake or a rolling machine. Bending helps in creating the required angle and ensuring the steel has the necessary strength and stability. Once the steel angle is cut and bent, it may need to be welded to join the different pieces together. Welding is a crucial process that ensures the strength and integrity of the steel angle. It involves heating the steel to its melting point and fusing the pieces together using a filler material. Finally, the steel angle goes through a finishing process. This may include surface cleaning, grinding, or polishing to remove any imperfections or rough edges. The finishing process helps in enhancing the appearance of the steel angle and also improves its corrosion resistance. Overall, the fabrication processes involved in manufacturing steel angles are cutting, bending, welding, and finishing. These processes are essential in creating steel angles that meet specific design requirements and quality standards.

Q:What are the different surface coating options for steel angles?: There are several different surface coating options available for steel angles, depending on the specific requirements and desired properties.
