Video: Punching is a process that is used to produce circular, rectangular or complex shaped holes. The ability to punch a material is dependent on the capacity of the equipment and the properties - thickness, strength and brittleness - of the material. Most structural steels, including the structural quenched and tempered grades up to 25mm thickness can be punched, but the process is less suitable for high strength or brittle materials. The ASI would like to thank Sebastian Engineering for their contribution to the suite of fabrication videos included in the Structural Steel Resource Kit.
