Fabricator markings on LGS steel

These will vary from supplier to supplier. Product markings on strapped packs and sometimes on individual items, identify the frame manufacturer and support verification of compliance of material with relevant design standard(s).

Typically, fabricated parts for LGS frames are coded with information to assist fabricators and erectors in the assembly and installation process. This matches the part information shown on the fabrication drawings and the frame number shown on the site assembly drawings.

Frame manufacturer markings typically include the following details:

  • Job Id
  • Frame Number
  • Part Number
  • Part Usage

In the below example, the job id is “office_sample”, wall is "W005" and "107" is the part number. (Note the Stud-10933 relates to the component and the size, however not all fabricators provide this)

Fabricator markings

In the factory, the fabrication crew uses this information for wall frame and truss assembly. On the site, the frame erection crew can use the same information to identify what the assembly is (“Frame Number”) and where it is intended to be used in the structure.

Different frame suppliers may use slightly different marking systems, but they should all be able to relate the wall frames and roof trusses to the site erection plans supplied.
