How to select the cutting method for Special Shaped Steel Cutting in Construction

What are the criteria for selecting a cutting method for Special Shaped Steel Cutting for Construction？
Thickness and Hardness: For thick plates (e.g., exceeding 1 inch), plasma cutting or laser cutting is preferred, while thin-walled steel sections are better suited for abrasive wheel saw cutting to minimize deformation and burrs.
Thick Plate Cutting: Plasma cutting (operating at temperatures of 20,000~30,000℃) can handle steel plates up to several inches thick, producing narrow kerfs and minimal distortion.
Complex Shapes: Laser cutting or CNC-controlled mechanical cutting (e.g., band saws, edge milling machines) enables high-precision machining of complex contours, reducing the need for subsequent processing.
