Weatherproof & Sealed Metal Enclosures for Outdoor Electrical Systems
Weatherproof and sealed metal enclosures are designed to protect electrical components, control systems, and sensitive devices from rain, dust, wind, and other environmental hazards. They are widely used in outdoor installations, industrial facilities, telecom systems, street lighting, and OEM electrical projects.
As a manufacturer of weatherproof metal enclosures, we produce weatherproof metal boxes, sealed metal enclosures, outdoor electrical enclosures, lockable metal housings, and custom sheet metal enclosures with padlock hasps according to customer drawings, samples, or project requirements.
For a broader overview of IP rated, waterproof, and outdoor metal enclosures, sheet metal fabrication processes, and industrial applications, you can also read our IP65 / Waterproof / Outdoor Metal Enclosure guide.
What Are Weatherproof & Sealed Metal Enclosures?
Weatherproof and sealed metal enclosures are protective housings designed to prevent ingress of water, dust, and other environmental contaminants while maintaining structural integrity for outdoor and industrial use.
Common features include:
- Weatherproof and sealed construction
- Dustproof and water-resistant design
- Lockable covers or padlock hasps
- IP65 / IP66 / IP67 / IP68 ratings
- Sheet metal fabrication
- Hinged or removable covers
- Grounding points
- Cable entry holes and knockouts
- Wall, pole, or floor mounting options
These enclosures are widely used for outdoor electrical panels, control systems, telecom devices, street lighting, battery enclosures, and OEM electronics.
Materials for Weatherproof & Sealed Enclosures
Material selection is critical for durability, corrosion resistance, and environmental protection.
Aluminum
- Lightweight, corrosion-resistant
- Suitable for outdoor and industrial applications
- Can be anodized, brushed, powder coated, or polished
Stainless Steel
- Strong, corrosion-resistant, and durable
- Suitable for harsh outdoor or industrial environments
- Brushed, polished, or passivated finishes
Carbon Steel
- Strong and cost-effective
- Powder coated or painted for water and weather protection
Galvanized Steel
- Provides basic corrosion protection
- Can be powder coated for additional outdoor durability
Fabrication Process
Weatherproof and sealed metal enclosures are fabricated using:
- Sheet Metal Cutting – laser cutting or punching for precise openings, cable entry, and mounting
- CNC Bending – forming the enclosure body, cover, or panels
- Welding and Assembly – joining parts, adding brackets, hinges, or compartments
- Drilling, Tapping, and Hardware Installation – installing PEM nuts, screws, grounding points, and padlock hasps
- Surface Treatment – powder coating, anodizing, brushing, painting, or polishing
- Quality Inspection and Packaging – ensuring IP rating compliance, dimensional accuracy, and surface quality
Applications
Weatherproof and sealed metal enclosures are used in:
- Outdoor control panels
- Industrial automation equipment
- Telecom devices
- Street lighting systems
- Battery and power supply enclosures
- OEM electronic products
- Metering and monitoring systems
- Security systems
- Automation equipment
They provide protection from rain, dust, wind, and other environmental hazards while supporting safe installation and long-term durability.
Choosing a Manufacturer
When selecting a manufacturer for weatherproof and sealed metal enclosures, consider:
