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.
Full Custom Sheet Metal Machining Solution
We can customize overall length, width, depth, hole position, port quantity and installation bracket structure fully per your drawings or samples. Precision CNC bending & laser cutting controlled within ±0.1mm tolerance, no secondary modification after motherboard assembly, greatly improving your assembly efficiency.
Pre-reserved Multi-Interface Layout, Wide Compatibility
Standard chassis reserves abundant space for VGA, HDMI, serial communication ports, Gigabit Ethernet, USB, terminal wiring and RF antenna ports. Suitable for POE monitoring host, motion controller, edge gateway, industrial gateway and various embedded industrial computer equipment integration.
Rugged SPCC Steel Structure & Premium Surface Treatment
Adopt thickened SPCC cold-rolled steel plate structure with strong compression & deformation resistance. Whole cabinet undergoes electrostatic anti-rust powder spraying, scratch-resistant, dust-proof and corrosion-resistant, adapting to harsh industrial workshop, outdoor cabinet and equipment room long-term operating environments. Designed with slotted ventilation vents for effective internal heat dissipation to prevent mainboard overheating.
Wall-mounted Installation Design, Space-saving Installation
Equipped with side fixed mounting brackets for easy wall-mounted installation, saves cabinet space, widely used in automation production lines, security monitoring engineering, intelligent transportation, industrial edge computing and on-site control cabinets.
Direct Source Factory Supply & Stable Delivery Capacity
No middleman markup, competitive ex-factory price for bulk orders. Support small trial order & large batch project orders, complete pre-production sample confirmation, full-process incoming & finished product QC inspection to guarantee uniform batch appearance and dimension. We provide one-stop OEM & ODM service including silk screen logo, color customization, surface finish upgrade for global industrial equipment manufacturers and system integrators.
