Hardware-installed panels
Panels, covers, brackets, and mounting plates with captive nuts, studs, inserts, screws, hinges, locks, or cable hardware.
Sheet metal assembly service
Sheet metal assembly service in China for OEM parts, hardware-installed components, and export packing.
Black Iron Metal supports finished sheet metal projects that need hardware, labels, subassembly checks, kitting, inspection, and packing requirements reviewed before quotation.
Best fit for finished or kitted sheet metal parts
Use this service when the RFQ needs more than fabricated parts in a carton. Assembly and packing details should be reviewed before sampling or repeat production.
- Hardware-installed panels, brackets, enclosures, covers, guards, doors, rails, and mounting plates.
- Basic subassemblies with captive nuts, studs, inserts, hinges, locks, labels, gaskets, foam, or protective film.
- Kitting and packing requirements for export cartons, pallet layout, warehouse labels, and receiving checks.
- Repeat production review for approved sample baseline, part separation, carton limits, label rules, and revision control.
Assembly and packing RFQ decisions
These details affect labor, inspection, receiving quality, and shipment protection. Define them before comparing suppliers.
| Decision area | Buyer risk | RFQ detail to include |
|---|---|---|
| Assembly scope | Unclear scope can hide hardware, labeling, gasket, insert, or fit-check labor from the quote. | Send assembly drawings, BOM, hardware list, label locations, gasket notes, and photos of the expected result. |
| Hardware sequence | Hardware installed before coating, after coating, or during final packing can change masking and damage risk. | Define captive nuts, studs, inserts, hinges, locks, screws, torque notes, and protected surfaces. |
| Fit and inspection | Parts can pass individual inspection but fail when hardware, covers, doors, or mating parts are assembled. | Mark mating holes, door gaps, alignment checks, label checks, thread checks, and functional inspection points. |
| Kitting and labels | Wrong labels, mixed revisions, or missing accessories can create receiving issues for overseas buyers. | Provide kit contents, part numbers, barcode or label format, bagging rules, revision status, and carton quantities. |
| Export packing | Finished surfaces, sharp edges, and heavy parts can scratch, deform, or be hard to identify after shipment. | Define separators, foam, film, carton limits, pallet method, stacking rules, label positions, and destination country. |
Typical assembly and packing work
These examples help buyers identify when the RFQ should include assembly-level review rather than only part production.
Enclosure subassemblies
Doors, shells, rails, internal brackets, gland plates, labels, gaskets, foam, and protective films prepared for buyer assembly.
Export kits
Grouped parts, accessory bags, labels, carton quantities, separators, and pallet layouts prepared for receiving and warehouse use.
Finished cosmetic parts
Powder coated or brushed parts that need protected faces, clean handling, visual inspection, and surface-safe packing.
Repeat-order packing
Approved carton method, label baseline, carton weight limits, part separation, and receiving notes carried across repeat orders.
Supplier transfer parts
Existing parts where photos, samples, inspection history, and current packing methods help set the baseline before quotation.
Inspection priorities for assembled and packed parts
Inspection should confirm both the part and the final condition the buyer receives after assembly, labeling, and shipment preparation.
Assembly fit
Check hole alignment, fastener position, door gaps, hinge movement, label placement, gasket fit, thread condition, and mating surfaces.
Finish protection
Review scratches, rubbing risk, sharp edges, exposed corners, protective film, bagging, foam, separators, and handling marks.
Receiving readiness
Confirm carton quantity, part number labels, kit contents, pallet method, carton weight, revision status, and destination-specific notes.

Sheet metal assembly FAQ
What should a sheet metal assembly RFQ include?
Send part drawings, assembly drawings, BOM, hardware specifications, labels, installation sequence, torque or fit notes when relevant, inspection points, packing rules, carton limits, destination country, and shipment method.
Which assembly details affect sheet metal quotation?
Quotation is affected by hardware type, fastener access, labels, gasket or foam requirements, fit checks, protective film, packing separation, carton limits, pallet rules, and whether the work is for samples, pilot builds, or repeat production.
How should export packing requirements be defined?
Define part separation, surface protection, bagging, carton size or weight limits, label format, pallet method, stacking limits, moisture protection if needed, and any receiving or warehouse rules from the buyer.
