Shenzhen Sanjun Hardware & Electrical Co., Ltd. – Custom Sheet Metal Outdoor Cabinets for Global Durability Demands
In the world of outdoor infrastructure, where equipment must survive rain, snow, extreme temperatures, and relentless wear, Shenzhen Sanjun Hardware & Electrical Co., Ltd. delivers bespoke sheet metal solutions that don’t just meet but exceed international standards.
Founded in 2010 and operating from a 5,000㎡ state-of-the-art facility in Shenzhen, we’ve built our reputation on merging cutting-edge technology (AMADA / Taimai Fu CNC punch presses, 3000W laser cutters, and precision bending systems) with decades of sheet metal expertise—making us the go-to partner for international clients seeking rugged, customized outdoor cabinets.
Core Product: IP65-Rated Outdoor Cabinets (Engineered for Extreme Durability)
Our outdoor cabinets are meticulously crafted from high-quality sheet metal, designed to meet the demanding needs of telecommunications, power, and infrastructure industries.
Key Advantages:
IP65 Waterproof & Dustproof Protection: Fully sealed against water ingress (even powerful jets) and dust intrusion, safeguarding equipment in rain, snow, or dusty environments.
Wide Temperature Resilience: Withstands extreme cold (-20℃) and high heat (+60℃), ideal for regions with drastic temperature fluctuations.
Anti-Peeling & Corrosion-Resistant Finish: Advanced surface treatment (powder coating or galvanization) ensures long-lasting color, resisting chipping, fading, and corrosion—even in UV-intensive or salty coastal areas.
Robust Structural Design: Precision-cut and welded for maximum integrity, handling physical impacts and heavy loads. Equipped with lifting eyes for easy installation.
Tailored Customization: Your Design, Our Expertise
We recognize every project’s uniqueness, offering full customization for outdoor cabinets:
Size & Structure Flexibility: Adapt dimensions and internal layouts—from compact enclosures to large-scale cabinets—to fit your equipment and spatial needs.
Functional Add-ons: Integrate shelves, cable management systems, locking mechanisms, or ventilation solutions, all tailored to your operational requirements.
Branding & Aesthetics: Custom colors, logos, or finishing techniques to align with your brand identity.
