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.
SanJun Hardware provides one-stop OEM & ODM full-process sheet metal customization service for photovoltaic AC distribution cabinet housings. Our complete manufacturing workflow includes laser blanking, CNC precise bending, heavy-duty reinforcement welding, custom cable gland holes, air duct heat dissipation processing, full-circle sealing groove forming, anti-UV powder coating and strict dimensional & sealing testing before shipment.
PV AC distribution cabinets feature highly differentiated internal layouts, busbar installation space, wiring ports and protection grade requirements based on different solar inverter power and project environments. Countless global solar engineering clients delay project progress because they cannot get qualified cabinet structural drawings, and hiring third-party industrial designers brings high extra costs and long waiting cycles. Our senior mechanical & electrical structural engineers offer zero-cost drawing development service for every client: according to your inverter power, internal busbar layout, required IP waterproof rating, indoor/outdoor installation method, local climate and electrical component size, we independently complete standardized 2D engineering drawings and 3D assembly simulation models, supporting unlimited free revisions until fully matching your on-site assembly demands. This service drastically cuts your independent design expenditure and shortens the whole project development & sample delivery cycle.
Multiple material options for different application scenarios: cold rolled steel, galvanized steel, SUS304 / SUS316 stainless steel. All semi-finished products go through deburring, rust removal and surface passivation treatment before coating; every finished enclosure passes dimensional inspection, water spray sealing test and static load test before delivery. Our factory holds ISO9001 quality management certification, all products meet international RoHS environmental compliance standards.
Our custom PV solar AC distribution cabinet sheet metal shells are widely deployed in all mainstream global photovoltaic power generation sectors:
