Product & Technological Portfolio: Yinlu's strength lies in its extensive and highly customizable product range, designed for a vast array of industries including new energy, industrial automation, petrochemical, telecommunications, water treatment, and power grid applications.

• Stainless Steel Solutions: The company offers a range of stainless steel enclosures built for durability. This includes the Stainless Steel Double-Door Outdoor Communication / Energy Storage Cabinet, made of 316 Stainless Steel with IP65 protection, a double-door design with a stainless steel handle lock and EPDM sealing strip, and built-in 19-inch mounting rails. Similarly, the Stainless Steel Pedestal Box, constructed from 316 Stainless Steel, offers IP55/IP65 protection and a pedestal floor-mounted installation method.
• Outdoor & Weatherproof Enclosures: For general outdoor control, the Rittal-style Free-standing Outdoor Control Cabinet, made of cold rolled steel, provides IP55/IP65 protection and is designed for floor-mounting in exposed environments. The Outdoor Weatherproof Control Enclosure, made of stainless steel, offers a higher IP66 protection level and is designed for wall-mounting.
• Control Consoles & Panels: For command and control centers, Yinlu manufactures consoles like the Industrial Monitoring Console and Modern Dispatch Console. These are constructed from cold-rolled steel (SPCC), offer IP54 protection, and feature a modular/integrated structure with an upper section for monitoring and a lower section for equipment storage. Installation is floor-standing with optional adjustable feet or casters.
• Specialized Custom Enclosures: The company excels in stainless steel non-standard custom enclosures, which are fully customizable in size, structure, and cutouts to protect specialized equipment in harsh industrial and outdoor scenarios, with protection levels up to IP65.
