Angle processing refers to all processes involved in forming steel with an L-shaped cross-section (angle steel) into a specified shape and dimensions. Primary processing methods include "cutting" using shearing, bandsaws, or gas/plasma cutting; "drilling" using drills or punching; "bending" using a press brake; and "welding" for joining with other components. Through these processes, angle steel is used in a variety of applications requiring strength and rigidity, such as beams, columns, and braces in building structures, frames and stands for machinery, and reinforcing materials. Processing precision and efficiency directly impact the quality and cost of the final product, making appropriate equipment and technology indispensable.
