Fabricate a welded steel frame, 2000 mm long, with a backing run on the main butt joint.
The suffix brings together two independent metrics from the standard: en iso 13920-bf
The code specifies the precision level required for the manufacturing of a welded part: Fabricate a welded steel frame, 2000 mm long,
Specifying is a clear signal to the fabrication floor: "Build this with standard professional care." It eliminates the need for individual tolerance notes on every single weld, streamlining the design process and ensuring that everyone from the engineer to the quality inspector is on the same page regarding what "good enough" looks like. Always refer to the latest version of ISO
