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.
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.
Countless global purchasers halt customization plans due to missing cabinet structural drawings and unaffordable industrial design expenses. SanJun Hardware launches exclusive free drawing optimization service to solve this trouble once and for all.
According to your actual battery dimension, internal component layout, required IP waterproof rating, installation method and local outdoor operating environment, our senior engineers will finish production-ready 2D/3D CAD drawings and targeted structural optimization at zero cost, supporting unlimited revision cycles. This service drastically cuts your independent design expenditure and shortens your whole project launch cycle.
