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
From flat blanks to finished enclosures, Black Iron Metal supports laser cutting, CNC bending, welding, fastening, finishing, assembly, inspection, and export packing.
Use this service when your project needs a supplier that can manage multiple sheet metal operations under one production workflow.

| 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 |
For sheet metal fabrication in China, the strongest RFQs connect the part use case with the checks needed before export packing.
Inspection usually focuses on door gaps, hinge and lock fit, grounding points, cable openings, coating coverage, and packing protection for visible panels.
Critical checks often include hole position, bend angle, flatness, weld strength, fixture fit, and whether mating hardware can be installed without rework.
Buyers should flag visible surfaces, burr limits, edge protection, hole alignment, label areas, masking needs, and carton separation before production starts.
Multiple sheet metal steps can be coordinated through one supplier instead of separate cutting, bending, welding, finishing, and packing vendors.
Potential manufacturing risks are reviewed before sample or production order, reducing late changes and avoidable cost.
RFQ details, drawing questions, packing notes, and shipment expectations are handled in a way overseas buyers can track.
We support custom enclosures, cabinets, panels, covers, brackets, frames, welded assemblies, and OEM sheet metal parts.
Yes. We support prototypes, pilot runs, and repeat production after drawings, material, finish, tolerance, and packaging requirements are confirmed.
Send 2D drawings, 3D files if available, material grade, thickness, finish, quantity, tolerance notes, packaging needs, and destination country.
Identify critical dimensions, mating features, visible surfaces, coating expectations, assembly fit checks, packing requirements, and the approved drawing revision before production begins.
