Buyer Guide

Quote Sheet Metal Parts from Sample Photos

A guide for buyers who have old parts, rejected supplier samples or reference photos but do not yet have complete CAD files.

Photos can start the review, not finish it

Sample photos help identify process route, visible defects, material clues and missing details. They are useful for a first feasibility screen, but final pricing still needs dimensions, material and tolerance assumptions.

Measure the dimensions that change fabrication

A few marked dimensions are more useful than many unmarked photos. Overall size, thickness, hole diameter, bend height, cutout locations and hardware positions help the reviewer judge the route.

Explain why the sample matters

State whether the sample is a good reference, a rejected part, a supplier rescue issue or an old part that needs replacement. The reason changes how the quote should be reviewed.

InputWhy it matters
Reference photosFront, back, side, detail views and any damaged or rejected areas.
Basic measurementsOverall size, thickness, hole diameters, bend heights and critical spacing.
Material cluesKnown material, magnet test, finish type, weight or environment.
Process needLaser cutting, bending, welding, hardware insertion, finish or replacement route.
Risk notesFit issue, coating defect, packing damage, supplier rescue or missing drawing.
Next file requestWhich DXF, STEP or PDF details are needed before final quote.

Next step

Use the guide to prepare a cleaner inquiry, then attach the best available files through the RFQ form. If an item is unknown, say so directly so the first reply can separate quote assumptions from confirmed requirements.
