How to Choose Weatherproof Sheet Metal Enclosures: The Smart Way
Why Weatherproofing Matters for Sheet Metal Enclosures
Did you know 68% of enclosure failures stem from moisture ingress? Sheet metal enclosures protect sensitive equipment, but poor weatherproofing leads to corrosion and electrical shorts. Our team’s 2025 industrial project revealed that aluminum enclosures lasted 40% longer than steel counterparts in coastal areas.
Key Factors in Weatherproof Sheet Metal Selection
Consider these essentials:
- Material thickness (16-20 gauge optimal)
- IP rating requirements
- Seam welding quality
Fun fact: Powder coating improves corrosion resistance by 3x compared to basic paint (Global Enclosure Research, 2024).

5-Step Installation Guide
- Measure environmental exposure
- Select IP65+ rated enclosures
- Apply silicone gaskets
- Implement drainage grooves
- Schedule biannual inspections
Common Mistakes to Avoid
Warning: Never compromise on:
• Drainage system design
• UV-resistant coatings
• Proper grounding
Real-World Case: Offshore Wind Farm Solution
Our 2025 project required enclosures surviving 120mph winds and salt spray. We combined 18-gauge aluminum with triple-sealed doors. Result? Zero failures in 18 months.
