Tubes & profiles.
Start with the section.
A shape becomes a useful specification when its dimensions, material and intended application are considered together.
Profiles
A shaped section needs both its outline and the dimensions that define it. Connection details, finish and application help explain the context.
Profile specification notesConfirm the actual requirement.
Grade range, dimensions, finish, quantity, documentation and supply arrangements need to be confirmed for the specific enquiry. These diagrams explain geometry; they are not a stock list or a production drawing.
