Part drawings are details of each individual part required on the job.
Parts are individual pieces of plate or lengths of section that need cutting to length notching, drilling or punching.
Each part drawing contains all the information required to fabricate a part, and includes the size and position of holes or notches required.
Parts can be sent directly in electronic NC format to steel suppliers to supply ready punched, notched and cut, leaving only the welding together of the assemblies ready to send to site.
