SanJun Hardware is an experienced OEM & ODM sheet‑metal manufacturer specializing in custom air‑cooled ESS AC‑DC integrated cabinet housings for global energy‑storage integrators and EPC contractors.

Overseas energy‑storage buyers frequently face tough custom‑manufacturing pain points:
‑ No mature structural drawings and expensive third‑party design expense
‑ Cabinet deformation under heavy‑weight battery pack load
‑ Mismatched air‑cooling duct structure, poor heat dissipation efficiency
‑ Failed outdoor sealing causing dust and water ingress
‑ Uneven welding seams and insufficient anti‑corrosion performance for long‑time field deployment

We solve these headaches with our core service: **100% free production‑ready CAD drawing design based on your project requirements. No self‑designed drawings from clients are required.**

Our complete manufacturing process includes high‑precision laser cutting, CNC bending, heavy‑load reinforced welding, reserved air‑cooling duct mounting positions, customized sealing structure, reinforced frame treatment and weather‑resistant powder coating. We strictly control machining tolerance, guarantee stable mechanical performance for heavy‑duty energy‑storage equipment.
