FAQ
Sheet Metal Fabrication RFQ Questions
Which drawing file formats can I upload?
You can upload PDF, DXF, DWG, STEP, STP, JPG, JPEG, PNG or ZIP files. A 3D model or clear PDF drawing is helpful when available.
What information helps you prepare a quotation?
Please share the drawing, required quantity, material, finish, assembly requirements and any critical dimensions or inspection needs.
How are tolerances confirmed?
Tolerances are reviewed against the drawing, material, part geometry, fabrication process and inspection method before the project is released.
Can you support prototype parts before repeat production?
Prototype and early production requirements can be reviewed from the drawing and project priorities before planning the next production stage.
Can welded sheet metal assemblies be quoted?
Yes. Include the welding joints, assembly scope, hardware, finish and any visible or functional requirements in the RFQ package.
Can you provide an inspection report?
Inspection records or reports can be included when they are agreed as part of the quotation and project acceptance requirements.
How are customer drawings handled?
Drawings are used for engineering review and quotation. Share any confidentiality requirements with the RFQ so they can be considered in the project discussion.
Can export packing be included?
Yes. Include destination, packing preferences and any document requirements so export packing can be reviewed with the project scope.
