Our outdoor power distribution cabinets are tailor-made carbon steel sheet metal housings designed for long-term outdoor harsh working conditions. Integrated sealing structural design achieves excellent waterproof, dustproof and anti-static effects, which can effectively shield internal electrical components from rain, sand, dust, static electricity and temperature fluctuation damage.
All cabinet dimensions, door structures, ventilation holes, cable inlets, lock configurations and IP protection levels can be fully customized to match your electrical layout and installation scenarios.
2. Core Competitive Advantages & Industry Difficulties We Have Overcome
✅ Exclusive Edge: Free Full CAD Drawing Design Service
Most sheet metal factories require purchasers to supply complete engineering drawings before quotation and production. SanJun Hardware breaks this threshold: you only need to inform us your installation space, internal component layout, required IP grade and functional demands. Our professional engineering team will complete all structural design drawings free of charge. You do not need to prepare any drafts by yourself, saving your R&D cost and communication cycle greatly.
✅ Technical Pain Points Solved Through Precise Sheet Metal Craft
- Resolved cabinet bending & welding deformation: Reinforced frame structure eliminates thermal deformation, keeping cabinet shape stable all year round outdoors
- Fixed uneven powder coating & poor anti-corrosion: Multi-layer outdoor weather-resistant baking paint ensures uniform surface, strong UV resistance & rust prevention
- Improved assembly dimensional error: Strict tight tolerance control guarantees perfect fitting of doors, locks and sealing strips
- Optimized sealing failure issue: Custom rubber sealing strips realize stable waterproof & dustproof performance under temperature variation
- Stable anti-static function: Professional surface treatment effectively eliminates static accumulation, protecting sensitive power modules
✅ One-Stop In-House Fabrication Workflow
Whole procedures finished inside our factory: Laser Cutting → CNC Bending → Seamless Welding → Precision Punching → Outdoor Grade Surface Spraying → Sealing Assembly. No need to cooperate with multiple suppliers, unified quality control, shorter lead time and lower comprehensive procurement cost.
3. Material & Surface Treatment Options
- Main Material: Cold rolled carbon steel, galvanized steel, optional stainless steel for coastal high salt spray areas
