FAQ
Questions international buyers ask
Which files can I send for a quotation?
You can send PDF drawings, STEP/STP, IGES/IGS, DXF, DWG and ZIP files, together with quantity, material, critical tolerances and delivery country.
Can material certificates be supplied?
EN 10204 3.1 material certificates can be supplied when requested and agreed during quotation. Source, form, dimensions and purchase conditions affect availability.
What if CMM inspection or a detailed dimensional report is required?
Dimensional inspection uses suitable conventional measuring equipment. Where CMM inspection, detailed dimensional reports or third-party verification are required, these services can be coordinated through a qualified measurement network.
