Black Iron Metal sheet metal fabrication workshop in China

Official export site of Wenzhou Black Iron Technology Co., Ltd.

Black Iron Metal sheet metal fabrication for global OEM buyers.

Black Iron Metal helps sourcing teams identify the official Wenzhou-based export contact, then turn drawings into consistent custom electrical enclosures, medical device enclosures, EV charger cabinets, industrial control boxes, OEM metal housings, brackets, and welded assemblies with clear DFM feedback and export packaging.

Step 1: type your work email. We reply with drawing checklist questions; files can follow later.

Click the email box first; one valid work email is enough to start.

After first contact, sales asks for drawings, material, quantity, finish, and packaging notes. Prefer direct email? Send drawings to sales@blackironmetal.com.

Start from the buyer path that matches your project.

Choose a product page when the enclosure type is clear, or review an industry page when application requirements need to be aligned before sending drawings.

MarketsGlobal OEM buyers, with focused support for North America, Europe, Australia, and other export markets

Built for buyers who need more than a low piece price.

Global OEM buyers usually care about repeatability, communication speed, traceable requirements, and shipping readiness. Black Iron Metal is organized around those buying criteria, with focused support for North America, Europe, Australia, and other export markets.

  • Drawing review for material, bend radius, tolerance stack-up, hole-to-edge spacing, welding distortion, and finish constraints.
  • One-stop process covering laser cutting, CNC bending, welding, riveting, powder coating coordination, assembly, inspection, and packing.
  • Useful RFQ guidance so buyers know what to send: 2D drawings, 3D files, material grade, finish, annual demand, packaging notes, and destination market.
  • Clear internal linking from broad service intent to specific quote-focused landing pages.

RFQ review

We check drawings, quantities, finish, packaging, and timeline, then ask focused questions before quoting.

DFM feedback

Engineers flag manufacturability risks and suggest practical changes for cost, repeatability, and assembly.

Sample or pilot run

Parts are produced with the selected process route, inspected, and documented before moving to repeat orders.

Production and export

QC checks, finish coordination, labeling, packing, and shipment support are handled as one workflow.

Representative work

Representative part categories include cabinets, equipment housings, EV charging enclosures, medical device covers, and precision cut components.

Questions buyers ask before sending drawings

Is Black Iron Metal the same as Wenzhou Black Iron Technology Co., Ltd.?

Black Iron Metal is the export brand used by Wenzhou Black Iron Technology Co., Ltd. for overseas OEM sheet metal fabrication inquiries from Wenzhou, Zhejiang, China.

What files should we send for a fast quote?

Send 2D drawings, STEP or STP files when available, material and thickness, finish, quantity, annual demand, packaging notes, and delivery destination. The sheet metal RFQ checklist shows the full preparation list.

Can you support prototypes and production orders?

Yes. The workflow supports prototype validation, pilot builds, and repeat production after drawings and process requirements are confirmed.

Do you help improve designs for manufacturability?

Yes. DFM feedback can cover bend feasibility, tolerance risks, welding distortion, fastener selection, finish constraints, and cost-saving alternatives.

Ready to source sheet metal parts from China?

Send drawings and sourcing requirements. If online submission is unavailable, the RFQ form opens a prefilled email so your inquiry is not lost.
