[0002] The aluminum columns of curtain walls are usually processed at the processing yard of the project site. Lines are drawn on the surface of the columns, and the pin holes are drilled using a bench drill or other equipment. When positioning and drilling holes at the processing yard, usually only lines are drawn on the surface of the columns.
