Custom Outdoor Electrical Enclosures for Harsh Industrial Environments
Outdoor electrical enclosures are designed to protect electrical systems, sensitive electronics, networking equipment, automation systems, and power distribution components from environmental exposure. These enclosures must withstand rain, dust, humidity, UV exposure, temperature fluctuations, and corrosive conditions while maintaining internal equipment safety and operational stability.
HLH manufactures custom outdoor electrical enclosures engineered for long-term outdoor performance. Our enclosures withstand rain, dust, UV exposure, and corrosive conditions while maintaining equipment safety. Our fabrication capabilities allow us to produce a wide range of enclosure configurations including:
- Wall-mounted enclosures
- Floor-standing cabinets
- Telecom enclosures
- Battery storage cabinets
- EV charger enclosures
- Junction boxes
- Climate-controlled cabinets
- Long-lasting control enclosures
We work with customers to customize dimensions, ventilation systems, cable management layouts, access panels, locking systems, and mounting configurations based on application requirements.
Material Options for Outdoor Electrical Enclosures
Selecting the correct material is critical for outdoor enclosure performance. Environmental conditions, corrosion exposure, structural requirements, and thermal performance all influence material selection.
HLH Sheet Metal Commonly Manufactures Outdoor Electrical Enclosures Using:
Stainless Steel
Stainless steel provides excellent corrosion resistance, structural strength, and long-term durability for outdoor applications exposed to moisture, chemicals, or coastal environments. Stainless steel 304 and 316 are commonly used for harsh industrial environments and infrastructure systems.
Aluminum
Aluminum enclosures provide lightweight strength, corrosion resistance, and excellent thermal conductivity. Aluminum is widely used for telecom systems, EV charging infrastructure, and outdoor electronic systems requiring weight reduction and heat dissipation.
Galvanized Steel
Galvanized steel offers cost-effective outdoor protection and strong structural performance. It is commonly used for utility enclosures, industrial control systems, and power distribution applications.
Surface Finishing Options
Powder coating, Anodizing, Galvanizing, Brushed finishes, Silk screening, and UV-resistant coatings.
