You Buy Manufacturing Capability, Not A Fixed Product

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.

Product Overview

SanJun Hardware provides one-stop OEM & ODM custom sheet metal service for 3-door metering distribution boxes. The whole production process includes laser blanking, precision CNC bending, reinforced full welding, independent separated meter compartment processing, cable inlet hole customization, rain-proof eave forming, double sealing slot manufacturing and electrostatic anti-rust powder coating.

Core Advantage: Free CAD Drawing Design, No Drawings Needed From Buyers

Three-door meter cabinets require separated independent compartments for multi-group electric meters, with customized wiring space, lock positions and wall-mounted sizes according to local power grid standards. Many foreign clients stall project progress because they lack professional structural drawings, and hiring external designers brings extra high cost and long waiting time. Our senior electrical structural engineers provide zero-cost drawing customization service. Based on your meter quantity, internal separation layout, required IP protection grade, wall/pole mounting way and outdoor climate environment, we independently finish production-grade 2D engineering drawings and 3D simulation models, supporting unlimited free revisions until fully matching your installation requirements. This greatly cuts your R&D cost and shortens sample & bulk order lead time.

Major Industry Problems We Overcome

  1. Outdoor water seepage, dust accumulation and salt fog corrosion: Integrated rainproof top brim + full-circle double EPDM sealing strip design stably realizes IP54/IP65 protection. Optional hot-dip galvanizing + UV-resistant coating adapts coastal, high-temperature, rainy and dusty harsh outdoor environments, effectively avoiding short circuit caused by water and dust.
  2. Cabinet deformation after long-term wall mounting: Thickened steel plate plus built-in reinforcing frame improves overall rigidity, no sagging or distortion after long-term installation with multiple meters inside.
  3. Uneven gaps between three cabinet doors & inaccurate mounting holes: Strict ±0.1mm machining tolerance ensures neat door seams, aligned mounting holes and convenient quick assembly of electric meters and wiring accessories.
  4. Poor internal heat dissipation & wiring chaos: Independent separated three-compartment layout, reserved layered heat dissipation windows and standardized cable routing channels to prevent meter overheating and facilitate maintenance inspection.
  5. Single fixed size cannot meet different regional grid standards: Fully customizable cabinet dimension, plate thickness, door lock style, number of meter positions, pole/wall mounting brackets and surface color; small trial orders and large engineering bulk orders are both acceptable with flexible MOQ.

Raw Material & Production Standards

Available materials: cold rolled steel, galvanized steel, SUS304 stainless steel. All workpieces are deburred, derusted and passivated before coating. Every finished meter cabinet will go through water spray test, dust test and load test before delivery. Our factory has ISO9001 quality certification, all products comply with RoHS environmental standards.

Applicable Industry & Usage Scenarios

  • Residential community multi-household metering power distribution
  • Commercial plaza, office building outdoor metering boxes
  • Rural power grid reconstruction engineering projects
  • Factory park outdoor power measurement cabinets
  • Outdoor street light monitoring power distribution equipment
  • Agricultural base, greenhouse power metering system
  • Coastal area, mining area anti-corrosion meter cabinet projects
  • Temporary construction site waterproof electricity meter boxes

😩 Typical Buyer Pain Points

  • No mature structural drawings for outdoor meter cabinets
  • Expensive third-party design fees before you can even quote
  • Water seepage and rust at door seams after outdoor installation
  • Compartments too small for multi-group meters and wiring
  • Lock and hinge failure after repeated field access
  • Coating fading and chalking under long-term UV exposure
