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.

✅ Complex Structural Design
Featured with multi-layer frameworks, densely arranged mounting holes and custom internal reinforcing brackets, they require sophisticated processing capabilities that ordinary sheet metal workshops cannot meet.
✅ Outstanding Structural Stability
Built with high rigidity to resist deformation and loose fitting caused by vibration during operation, transportation and on-site installation. Thick industrial-grade metal sheets and optimized reinforcing structure guarantee strong load capacity and impact resistance.
✅ Reliable Comprehensive Performance
Excellent sealing, heat dissipation and electromagnetic isolation are well balanced. The surface coating provides outstanding anti-corrosion, anti-rust and anti-aging properties, perfectly adapting to outdoor energy storage stations, factory workshops and high temperature & high humidity working conditions.
Burr-free cutting and accurate hole positioning, enabling seamless assembly with electronic components and fittings.
Guarantees uniform specifications and stable structural strength for profiled parts and mass production.
Strict angle tolerance control ensures even and neat assembly gaps across the whole unit.
Eliminates gaps thoroughly and greatly improves the overall tightness of cabinets.
Forms a thick protective layer that is scratch-resistant, UV-resistant and anti-corrosive, effectively prolonging the service life in harsh scenarios.
As a professional manufacturer specializing in high-difficulty sheet metal products for new energy industry, we stand out from general processing factories:
🔹 Rich experience in producing high-precision, complex-structured and high-sealing enclosures for energy storage and industrial control equipment.
🔹 Capable of tackling various customized challenges, including irregular cabinet shapes, complex hole layouts, ultra-flat surface requirements and strict sealing standards.
🔹 Complete in-house production lines covering all procedures from cutting, stamping, bending, welding and polishing to automatic powder coating, realizing one-stop manufacturing and timely delivery.
🔹 Rigorous tolerance management keeps assembly errors to a minimum. Our professional engineering team can optimize designs based on clients’ drawings to reduce weight, improve heat dissipation and enhance structural stability, helping clients boost product competitiveness.
