Sheet Metal Enclosure RFQ: What to Send

A practical checklist for engineers and buyers preparing a drawing-based enclosure request. Missing details can be discussed rather than guessed.

Sheet Metal Enclosure RFQ: What to Send — enclosure concept
Illustrative structure, not a customer case study. Supply follows approved drawings.

Start with scope and revision

List part numbers, drawing revisions and quantities per assembly. Distinguish prototype quantity from the expected batch quantity. State whether the request is for loose parts or an assembled housing.

Use drawings to define acceptance

A 3D model describes geometry but may not include tolerances, material or finish. Attach a dimensioned drawing identifying critical interfaces, threads, inserts, welding requirements and the intended inspection points. Flag unresolved dimensions before quotation.

Describe appearance and delivery

Include material grade, thickness, color, texture, masking, printing artwork and packaging requirements. State the requested delivery date and destination for review, without treating either as a confirmed supplier commitment.

When the drawing is confidential

Begin with a non-confidential outline, intended use and quantity. Agree confidentiality arrangements before releasing sensitive files. Do not remove dimensions from a production drawing without marking it as incomplete.

Start a drawing-based review

Share the application, quantity and known requirements. An unfinished drawing can start a discussion. Materials, process, inspection and delivery require project-specific agreement.
