SanJun Hardware is a professional sheet metal factory specialized in custom three-door metering distribution cabinets for global power engineering, property management and energy enterprises.
Most overseas purchasers face big troubles: no ready-made cabinet drawings, high design costs, water leakage & dust ingress outdoors, cabinet bending deformation, messy internal wiring layout and inconsistent assembly gaps. We fully solve all these industry pain points with our core service: totally free engineering drawing design, customers don’t need to provide any self-drawn sketches.
We own full production lines for laser cutting, CNC bending, full sealing welding, rainproof structural processing and weather-resistant coating, with machining tolerance controlled within ±0.1mm. Our 3-door meter cabinets reach IP54/IP65 waterproof dustproof standard, pass ISO9001 & RoHS certification, widely used in all kinds of indoor and outdoor power metering scenarios worldwide.
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.
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.
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.
