Equipment enclosures
Inspection usually focuses on door gaps, hinge and lock fit, grounding points, cable openings, coating coverage, and packing protection for visible panels.
One-stop fabrication
Sheet metal fabrication in China for OEM parts and assemblies.
From flat blanks to finished enclosures, Black Iron Metal supports laser cutting, CNC bending, welding, fastening, finishing, assembly, inspection, and export packing.
Visual fabrication RFQ routes
Use these image-led paths to match your drawing package with the right process, product family, and export packing notes before requesting a fabrication quote.
Cut blanks and panels
Laser-cut profiles, cut-edge quality, hole patterns, sheet thickness, nesting notes, and burr expectations.
Bent brackets and covers
Bend radius, flange length, hole-to-bend distance, fit dimensions, and formed part repeatability.
Welded assemblies
Weld size, fixture control, distortion risk, cleanup level, visible surfaces, and inspection points.
Finish and visible faces
Powder color, gloss, texture, masking zones, corrosion exposure, approval samples, and handling marks.
Enclosures and control boxes
Doors, mounting plates, cable entries, grounding points, ventilation, hardware, and repeat production context.
Assembly and export packing
Hardware sequence, fit checks, labels, carton limits, separators, pallet rules, and destination notes.
Best fit for complete metal fabrication projects
Use this service when your project needs a supplier that can manage multiple sheet metal operations under one production workflow.
- Custom enclosures, cabinets, panels, brackets, covers, doors, frames, and welded assemblies.
- Materials commonly include stainless steel, carbon steel, galvanized steel, and aluminum.
- Process planning for cutting, bending, welding, riveting, hardware insertion, surface finishing, and assembly.
- Export-oriented packing for sea, air, or courier shipment, with labeling and carton requirements confirmed before production.
Fabrication scope
| Stage | What we handle | Buyer inputs needed |
|---|---|---|
| Drawing review | Manufacturability, bend feasibility, weld access, tolerance risks, finish conflicts | 2D drawing, STEP file, material, thickness, finish, critical dimensions |
| Fabrication | Laser cutting, punching where suitable, CNC bending, welding, grinding, hardware insertion | Annual demand, order quantity, visible surfaces, assembly notes |
| Finishing | Powder coating coordination, plating, anodizing, brushing, passivation where applicable | Color code, gloss, corrosion expectation, masking areas |
| Quality and packing | Dimensional checks, appearance inspection, fit checks, protective packing, labeling | Inspection priority, packing rules, carton limits, destination country |
Common buyer projects and inspection focus
For sheet metal fabrication in China, the strongest RFQs connect the part use case with the checks needed before export packing.
Mounting brackets and frames
Critical checks often include hole position, bend angle, flatness, weld strength, fixture fit, and whether mating hardware can be installed without rework.
Control panels and covers
Buyers should flag visible surfaces, burr limits, edge protection, hole alignment, label areas, masking needs, and carton separation before production starts.
Why overseas buyers use this service
Less supplier coordination
Multiple sheet metal steps can be coordinated through one supplier instead of separate cutting, bending, welding, finishing, and packing vendors.
DFM before production
Potential manufacturing risks are reviewed before sample or production order, reducing late changes and avoidable cost.
Export communication
RFQ details, drawing questions, packing notes, and shipment expectations are handled in a way overseas buyers can track.
Sheet metal fabrication FAQ
What types of sheet metal parts do you make?
We support custom enclosures, cabinets, panels, covers, brackets, frames, welded assemblies, and OEM sheet metal parts.
Can you support both prototypes and repeat production?
Yes. We support prototypes, pilot runs, and repeat production after drawings, material, finish, tolerance, and packaging requirements are confirmed.
What should be included in a fabrication RFQ?
Send 2D drawings, 3D files if available, material grade, thickness, finish, quantity, tolerance notes, packaging needs, and destination country.
Which inspection details should buyers define before production?
Identify critical dimensions, mating features, visible surfaces, coating expectations, assembly fit checks, packing requirements, and the approved drawing revision before production begins.
