Drafting Conventions For Structural Steel Fabrication

Drafting Conventions For Structural Steel Fabrication


by Estelle Larsen


The structural drafter must possess a drawing technique that reflects the strict control of lines of a drawing for mechanical uses. This is the mark of an authentic and aesthetic engineering accomplishment, with the details of the draft following a stringent uniformity and consistency. While line drafting is rigid, adding stylized techniques to produce artful yet crisp finished work is a crucial contribution to the actual output.

Because the roots of the framework of building depends on the drafts of the engineer and the architect, they should be depicted detail by detail. Such in structural steel fabrication and ironworks, the maker of the draft should be educated in technical lingo, erection, and overall engineering to be able to translate the project well into his sketch. The principles are standard and should be thoroughly followed.

The basic lettering height and dimensioning is three over thirty two. Sketches should be numbered accordingly with the capital letter s hyphenated before the number of the sketch and should have height of one fourth or more. Scales are in standard feet and inches and must be always written. Indicate not to scale if the detail does not scale the notation. Otherwise, write scale as noted in the title block.

Every entity in the draft must contain a title. It could be an elevation, detail, symbols legend, plan view, or note column, among others. It should be large enough to catch attention and underlined, and the height ranges from one fourth to three eighths of an inch.

Deleted sections are depicted through section marks. They are circles with arrows, like in engineering. The circle is typically one half inch in terms of diameter. An forty five degree arrow directs the deletion. They can either be colored or left open. The title of the section view must be included in the upper half moon of the circle, while the sheet reference should me mentioned in the lower half moon part.

Structural presentations should also contain the north arrow as a reference to the components which they relate to. Drawing tools should be used as they are never made freehand. Color can be implemented to strike the viewer, but they should be simple.

Title blocks should contain seven kinds of information. The project title and the drawing name, the name of the client and his address, the name of the structural company and its address, the date when the package was completed, the drawing scale and number, and the professional stamp of the structural engineer must all be present. Lettering should be centered or in a flush margin.

For any modifications prior to the approval of the structural sketch, revision blocks should be used. A list called bill of materials should embody the ingredients of the framework. A border, generally a half inch by line, should wrap the sheet.

The line work should strictly follow the recommended standards, with arrowheads either drawn open, closed, solid, or traditional. Local and general notes should be placed horizontally on the sheet and abbreviations are strongly discouraged. Do not forget to reference each note with a number, and spacing should make the notes distinguishable from each other.
