Edge or end condition
- Edge or end condition is confirmed from the product form, standard and downstream fabrication need.
Testing and inspection
- Tests required by the governing purchased standard.
- PMI, NDE, corrosion, roughness or other supplementary inspection only when specified and confirmed in the quotation.
Order documents
- Inspection document type and content as ordered.
- Heat or lot traceability and supplementary reports when included in the accepted inspection plan.

Choosing the right finish
Most fabrication work uses 2B — the smooth, matte cold rolled finish that welds and forms predictably. BA (bright annealed) suits appliance fronts and reflectors; No.4 and hairline are the standard brushed decorative finishes; 8K mirror is used for elevator cabins and feature walls. Protective film can be specified and is confirmed with the finish and packing route.
Tolerance and flatness
Thickness tolerance follows the governing dimensional standard. Tighter thickness, flatness or diagonal tolerances for laser-cut panels must be stated in the RFQ and accepted for the quoted processing route.
What you receive
Inspection documents, PMI and other verification are supplied only when included in the accepted order and inspection plan. See our quality control process for the full inspection flow.
