Waterproof Metal Enclosures for Industrial & Outdoor Applications
Waterproof metal enclosures are designed to protect electrical components, control equipment, and sensitive devices from water, dust, and environmental exposure. They are widely used in outdoor installations, industrial facilities, street lighting, telecom systems, battery enclosures, and OEM electronics.
As a manufacturer of waterproof metal enclosures, we produce waterproof metal boxes, waterproof sheet metal enclosures, custom waterproof enclosures, waterproof electrical enclosure boxes, and customized sheet metal housings 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 Waterproof Metal Enclosures?
Waterproof metal enclosures are protective housings made from sheet metal or fabricated metal parts, designed to prevent water ingress while providing mechanical protection for electrical and electronic components.
Common types include:
- Waterproof metal enclosures
- Waterproof metal enclosure boxes
- Waterproof sheet metal enclosures
- Waterproof electrical enclosure boxes
- Customized waterproof sheet metal enclosures
- IP65 / IP66 / IP67 rated enclosures
These enclosures are used for outdoor control panels, telecom equipment, street lighting, industrial power systems, battery enclosures, and OEM electronics.
Materials for Waterproof Metal Enclosures
Material selection affects corrosion resistance, durability, and environmental protection.
Aluminum
- Lightweight and corrosion-resistant
- Suitable for outdoor and industrial applications
- Can be anodized, brushed, or powder coated
Stainless Steel
- Strong, corrosion-resistant, and suitable for harsh outdoor conditions
- Brushed, polished, or passivated finishes
Carbon Steel
- Strong and cost-effective
- Usually 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
Waterproof metal enclosures are fabricated using:
- Sheet Metal Cutting – laser cutting or punching to create precise openings for cable entry and mounting
- CNC Bending – forming the enclosure body, cover, or panels
- Welding and Assembly – joining parts, adding internal brackets, hinges, or compartments
- Drilling, Tapping, and Hardware Installation – installing screws, PEM nuts, cable glands, and grounding points
- Surface Treatment – powder coating, anodizing, brushing, or painting
- Quality Inspection and Packaging – ensuring IP rating compliance, dimensional accuracy, and surface quality
Applications
Waterproof metal enclosures are used in:
- Outdoor control panels
- Industrial automation equipment
- Telecom devices
- Street lighting systems
- Battery and power supply enclosures
- OEM electronic products
- Junction boxes and distribution enclosures
These enclosures protect electrical components from water, dust, and environmental hazards, ensuring long-term reliability.
Choosing a Manufacturer
When selecting a manufacturer for waterproof metal enclosures, consider:
- Sheet metal fabrication and CNC bending capabilities
