<p>SanJun Hardware is a professional non-standard precision sheet metal processing factory based in Rugao, specializing in customized metal housings for blade battery packs and new energy energy storage chassis for global new energy enterprises.<br />
Most overseas buyers face huge troubles when customizing non-standard battery cabinets: lacking structural design drawings, high independent design costs, poor cabinet structural strength, insufficient outdoor waterproof and anti-corrosion performance, and inconsistent assembly gaps. We completely solve these industry pain points with our exclusive service: completely free production-ready CAD drawing design, customers do not need to provide any self-drawn drafts.<br />
Our full-process sheet metal workshop realizes integrated production from laser cutting, CNC bending, full penetration welding to weather-resistant surface coating, with machining tolerance controlled within ±0.05mm~±0.1mm. All non-standard blade battery boxes and energy storage chassis comply with ISO9001, RoHS and IP protection standards, widely applied to household energy storage, industrial & commercial energy storage, new energy vehicles, RV power supply, off-grid solar energy storage and other global scenarios.</p>
<p>SanJun Hardware is a specialized precision sheet metal manufacturer for new energy, dedicated to custom off-grid integrated battery cabinet enclosures for global energy storage integrators and power equipment brands.<br />
Most overseas buyers struggle with unavailable structural drawings and exorbitant industrial design costs for cabinet customization—we break this industry bottleneck by offering 100% free full-grade 2D & 3D drawing design, no design drafts required from clients.<br />
Our professional engineering team thoroughly resolves core industrial pain points: heavy-load cabinet sagging deformation, substandard outdoor waterproof & dustproof performance, uneven assembly gaps, and weak anti-corrosion capacity. We deliver standard machining tolerance of ±0.1mm and ultra-precision custom tolerance up to ±0.05mm. All sheet metal enclosures pass ISO9001, RoHS, EMC and LVD certification, fully adaptable to all indoor & outdoor off-grid energy storage scenarios worldwide.</p>
