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.
Our custom sheet‑metal enclosures are professionally engineered for 120 kW and 160 kW high‑power DC EV charging piles. As a professional sheet‑metal fabrication factory, we integrate industrial‑grade structural stability, extreme weather resistance, and refined industrial aesthetics into each housing. Every cabinet is tailor‑made for high‑power charging equipment, perfectly adapting to complex outdoor environments including public charging stations, highway service stations, commercial parking lots, industrial parks, and residential charging hubs. Adopting one‑stop OEM & ODM customized production, our enclosures deliver comprehensive protection for long‑term stable operation of electric vehicle charging equipment.
We supply multiple high‑strength industrial metal material options, including cold‑rolled steel, galvanized steel, and SUS304 stainless steel with customizable plate thickness. All raw materials feature high rigidity, strong impact resistance, compression resistance and load‑bearing capacity, which can effectively resist external collision, extrusion and mechanical damage under outdoor conditions. With outstanding anti‑corrosion, anti‑UV, anti‑aging and weatherproof performance, the housings withstand harsh environments such as heavy rain, snow, high temperature, low temperature and strong ultraviolet radiation, preventing rust, fading, deformation and aging over long‑term outdoor service.
We follow full‑process standardized sheet‑metal manufacturing procedures, covering precision laser cutting, CNC bending, high‑precision stamping, seamless welding, and outdoor electrostatic powder coating. All processing is strictly controlled under industrial tolerance standards to guarantee accurate hole positions, smooth assembly and zero structural deviation. Robust seamless welding improves overall airtightness and structural firmness, while thickened outdoor powder coating boosts scratch resistance, anti‑fading performance and surface texture. Every production step undergoes rigorous inspection to rule out defective units and maintain consistent high‑quality output.
The enclosure adopts a reinforced integrated frame structure, effectively enhancing overall rigidity and anti‑deformation performance to avoid structural loosening after long‑term operation. Human‑engineered reserved wiring openings, mounting holes and internal installation positions greatly simplify equipment assembly, cable arrangement and routine maintenance. Fitted with high‑quality waterproof rubber gaskets and professional cable glands, the cabinet achieves IP54 / IP65 dust‑proof and water‑proof ratings. The independent heat‑dissipation channel balances cooling efficiency and dust resistance, lowering module operating temperature and extending the service life of charging hardware. Meanwhile, the anti‑theft lock design blocks unauthorized access and safeguards equipment security.
We support comprehensive personalized customization to satisfy diverse brand and project requirements. Customizable items include overall dimensions, outer shape, interface locations, hole layout, shell color (full RAL color matching), laser‑engraved logos and internal structural schemes. Our professional engineering team delivers free CAD drawing design, 3D scheme optimization and DFM technical support. From prototype sampling to mass production, we provide one‑stop customized solutions for various brands of 120 kW / 160 kW high‑power charging piles.
All charging‑pile enclosures receive 100% thorough quality inspection prior to shipment, including dimension testing, waterproof‑performance testing, structural‑stability testing and surface‑quality checks. Products comply with CE, RoHS standards and operate under the ISO9001 quality‑management system, fully meeting EU market‑access requirements. Stable, reliable product quality supports 24/7 continuous safe operation of charging equipment under all‑weather outdoor conditions.
