Hardware buying guide
Define the stock, cutting, forming, and finishing your part needs. A flat cut panel and a welded enclosure require different manufacturing scopes.

Build a sheet metal brief →03 / Compare
Use the same stock grade, thickness, bend specification, hardware, and finish for each quote. Separate flat cutting from forming and assembly, and confirm whether dimensions apply before or after finishing.
Compare provider details →Show the intended assembled shape and the interfaces that matter. Confirm who generates the flat pattern and which bend assumptions the supplier will use. SendCutSend publishes material-dependent bend specifications; apply the proposed fabricator's reviewed rules to the chosen stock rather than carrying assumptions from another shop.
Ask the supplier to review cutting, bending, hardware, joining, and finish as a sequence. A quote for cut panels does not establish that a finished enclosure is included. Get an answer for the complete scope and the inspection evidence that will demonstrate fit.
Use these evidence requests to resolve the project scope before ordering.

| Question | Evidence to request | Needs clarification |
|---|---|---|
| Are the bends feasible in this stock? | A review of material, thickness, flange geometry, and bend sequence. | A flat-cut quote that never addresses the formed shape. |
| Are hardware and finish included? | Named hardware, installation scope, finish, and exclusions. | A single fabrication line item with no secondary-operation breakdown. |
| How will assembled fit be checked? | An agreed fit check or measurement plan tied to the formed drawing. | Only flat dimensions are checked even though assembly depends on bends. |
Illustrative project: a 25-unit electronics enclosure needs bent sides, threaded hardware, powder coating, and a lid that closes. Send both the flat and assembled views, with one revision identifier. Ask each candidate to price the same finish and hardware and explain how lid fit is checked. If one supplier proposes a different bend radius, review its impact on the assembly before approving a new file.
Ask each candidate to review it against its tooling and bend assumptions. Keep the formed geometry and critical interfaces controlled while agreeing any flat-pattern revision.
Confirm joining explicitly. Cutting, forming, hardware installation, welding, and finishing may be separate operations or outside a provider's scope.
Start with the interfaces that determine assembly and use. Agree the required measurements and whether they apply before or after finish.

Documented service scope
These records have an official capability source. Details may cover one service within a provider's wider offering; confirm the process and material combination for your project.
Processes: Sheet metal laser cutting, Tube laser cutting, Metal punching, CNC machining, Finishing and assembly coordination
Scope and buying questions: Confirm the partner sites and who owns each manufacturing step. How are changes, quality exceptions, and handoffs controlled across processes? Specify the finished assembly's acceptance criteria and which inspection records reach your team.
Official capability source →Processes: Laser cutting, Sheet metal fabrication
Scope and buying questions: Which secondary operations are supported for the chosen material and thickness? Confirm bending, hardware, finishing, and inspection in the quote. Check the final dimensions and revision used for production; testimonial examples are not acceptance specifications.
Official capability source →Processes: Laser cutting, Laser engraving, Bending, Tapping, Design for manufacturability review
Scope and buying questions: Confirm the stock, thickness, edge condition, bend allowance, and tapped features. Does the quote include all secondary work? Check units and drawing revision, and agree on inspection of the finished part rather than only the flat cut profile.
