Custom IP66 Outdoor Waterproof Stainless Steel Electrical Enclosure Box Wall-Mounted NEMA 4X

Product Overview

Built around the application.

Premium Custom Outdoor Stainless Steel Electrical Enclosures

Engineered for the most demanding environments, our Custom Outdoor Waterproof Stainless Steel Electrical Enclosures provide uncompromising protection for sensitive control systems, power distribution networks, and industrial automation components. Manufactured by utilizing advanced precision sheet metal fabrication techniques, these enclosures are built to withstand severe weather, corrosive atmospheres, and high-impact physical stress.

Whether you are outfitting a solar farm, a telecommunications cell tower, or a water treatment facility, our electrical control boxes deliver a certified IP66 and NEMA 4X protection rating, ensuring your internal electronics remain safe from water ingress, dust, and environmental degradation.

Key Features & Engineering Advantages

• Weatherproof Sloped Roof Design: Features an integrated rain hood (sloped roof) that effectively repels water, snow, and debris, preventing pooling and extending the lifespan of the enclosure.
• Superior Corrosion Resistance: Forged from premium-grade SUS304 or SUS316L stainless steel, offering exceptional resistance against rust, chemical exposure, and marine environments.
• Seamless Welded Construction: Continuous seam welding ensures maximum structural integrity. The automated robotic welding process eliminates gaps, fully reinforcing the waterproof capabilities.
• Polyurethane (PU) Sealing Gasket: The inner door features a poured-in-place PU foam gasket that guarantees an airtight and watertight seal over years of continuous outdoor use.
• Thermal Management: Equipped with precision-stamped louvered ventilation slots (optional) to allow heat dissipation while preventing rain entry, crucial for high-load electrical components.

Comprehensive Technical Specifications

Internal Configuration & Ease of Installation

We understand that time is money in industrial installations. Our enclosures come standard with a removable galvanized steel mounting plate (thickness up to 2.5mm) to allow engineers to assemble DIN rails, circuit breakers, contactors, and wiring off-site. The bottom features a removable gland plate for easy, secure, and fully sealed cable entry and routing.
