Precision Sheet Metal Fabrication Outdoor Carbon Steel Power Distribution Cabinets, Waterproof, Dustproof & Anti-static for Outdoor Application

SanJun Hardware is a seasoned precision sheet metal manufacturer specializing in customized outdoor power distribution cabinets. We adopt carbon steel as primary raw material to fabricate robust electrical cabinets featured with IP-rated waterproof, dustproof and anti-static performance for harsh outdoor environments.
Our biggest competitive advantage: we provide free customized CAD drawing design based on your actual demands, no finished drafts required from buyers. Our in-house one-stop production solves classic industry defects including cabinet deformation, uneven spraying, poor assembly tolerance and failed sealing performance. Widely applied in power grid, energy storage, charging station and outdoor automation projects, we support OEM customization for all sizes and protection grades.

1. Product Overview

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

  1. Resolved cabinet bending & welding deformation: Reinforced frame structure eliminates thermal deformation, keeping cabinet shape stable all year round outdoors
  2. Fixed uneven powder coating & poor anti-corrosion: Multi-layer outdoor weather-resistant baking paint ensures uniform surface, strong UV resistance & rust prevention
  3. Improved assembly dimensional error: Strict tight tolerance control guarantees perfect fitting of doors, locks and sealing strips
  4. Optimized sealing failure issue: Custom rubber sealing strips realize stable waterproof & dustproof performance under temperature variation
  5. 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
  • Surface Finish: Outdoor weather-proof powder coating, anti-rust primer + topcoat, salt spray resistant treatment
  • Protection Performance: IP54 / IP55 / IP65 customizable waterproof & dustproof grade, persistent anti-static property
  • Customizable Items: Cabinet thickness, external size, lock style, ventilation panels, cable glands, mounting brackets

4. Wide Application Scenarios

Outdoor power distribution stations, solar energy storage systems, EV charging pile control cabinets, roadside automation equipment, communication base station power cabinets, industrial outdoor control boxes, municipal engineering power facilities.

5. Factory Quality Assurance

All products comply with ISO quality management system & RoHS environmental standards. Every cabinet passes waterproof test, dust test and dimensional inspection before delivery. We accept small trial orders and mass bulk production, guarantee on-time delivery for global industrial buyers.
