Cost	More affordable	Long lifespan, lower long-term cost	N/A	Higher upfront cost
Thermal Conductivity	Excellent for heat dissipation	Lower, may need extra cooling	N/A	Poorer heat dissipation
Strength	Moderate, can dent	High, resists dents and wear	Prone to dents and scratches	Heavy, tough to move
Best Use Cases	Coastal, telecom, solar, moderate	Harsh, high-security, hygienic	N/A	N/A

You might also consider non-metallic enclosures like fiberglass or polycarbonate. These are lightweight and resist corrosion, making them perfect for wet or chemical-heavy sites. However, they don’t offer the same impact resistance or EMI shielding as metals. Metal enclosures, like those from Linkwell, provide better physical protection and shield sensitive electronics from electromagnetic interference. Non-metals work well when you need easy installation and don’t face heavy impacts.

Tip: For harsh industrial sites, stainless steel stands up to abuse and corrosion. For lighter, cost-sensitive jobs, aluminum or non-metals can save you time and money.

Protection Ratings (NEMA, IP)

Now, let’s talk about protection ratings. NEMA and IP ratings tell you how well an enclosure keeps out dust, water, and other hazards. NEMA ratings cover a wide range of threats, including corrosion, ice, and oils. IP ratings focus on dust and water ingress.

NEMA Rating	Protection Level	Typical Use Case
NEMA 1	Basic indoor protection	Control panels in dry areas
NEMA 3R	Rain, sleet, ice	Outdoor telecom and utility enclosures
NEMA 4	Hose-directed water, windblown dust	Washdown, outdoor environments
NEMA 4X	Same as 4, plus corrosion resistance	Coastal, chemical, food processing
NEMA 12	Oil, dust, dripping liquids	Industrial manufacturing

When you pick a rating, think about where you’ll use the electrical panel enclosure . Outdoor sites with rain or salt air need NEMA 4X or IP66. Dusty factories do well with NEMA 12 or IP54. Linkwell Outdoor electrical panel enclosure meet UL, CE, NEMA, and IP standards, so you know you’re covered for harsh conditions. Their electrical panel enclosure come with features like UV-resistant coatings, tight gaskets, and certified accessories to keep your equipment safe.
