Custom sheet metal, not off-the-shelf — built around your exact requirements.
Every cabinet on this page was built for a specific project. Your dimensions, materials, protection grade, door layout and cable entries are all decided by you — we handle structure design, process planning, fabrication and testing. This page shows what we have done and what we can do for your project.
SanJun Hardware is an OEM factory specialized in precision custom sheet‑metal fabrication, supporting prototype development through mass‑volume serial production. We process premium‑grade stainless steel, aluminum alloy, cold‑rolled steel and galvanized steel materials to manufacture brackets, mounting parts, equipment housings, panels and assorted custom metal components.
Our core manufacturing workflow covers advanced fiber laser cutting, high‑precision CNC bending, stamping, drilling, riveting and welding. Multiple surface finishing options are available including powder coating, anodizing, electroplating, grinding, polishing and wire‑drawing to satisfy diverse appearance and anti‑corrosion demands.
Many overseas integrators face typical custom‑manufacturing pain points: expensive third‑party structural design, poor dimensional repeatability between batches, tolerance mismatch during component assembly, and complicated multi‑vendor sourcing.
We resolve these pain points with our core service: 100% free production‑ready CAD drawing design according to your project requirements. No self‑designed drawings are required from clients.
Our whole‑plant ISO9001 quality‑management system strictly controls every production procedure. Full‑range inspections ensure each finished part meets international quality standards, enhancing buyers’ confidence in long‑term product reliability.
Self‑service kiosk housings, medical equipment, digital signage, industrial control devices, automation machinery, vending machines, new‑energy equipment and other industrial custom hardware projects.
No drawings? No problem. Send your power module specs — our engineers deliver manufacturable CAD drawings free of charge, saving you $500+ in third-party design fees and weeks of engineering time.
