Waterproof Submersible Enclosure Rating Chart
Our waterproof enclosures are compatible with both NEMA and IP ratings: NEMA 6/6P and IP67/IP68.
100% Waterproof Performance Tested – Quality Guaranteed
Nemaco has factory quality control standard procedures on all waterproof enclosures manufactured and tested before shipping to customers. The basic standard requires that every enclosure is tested for a full 24 hours under simulated environmental conditions and inspected to have no leaks on the gaskets or any conduit hubs, pipe fittings or windows if applicable.

Standard QC Testing Requirement
We test all waterproof enclosure designs to pass NEMA 6 and 6P criteria of UL 50/50E and NEMA 250 standards, ensuring protection under 6 ft (1.8 m) of water for 24 hours.
Top Quality Materials Only
Quality corrosion-resistant materials are used for the NEMA 6P rating. Each application might be different, and our team will work with you to select the right material.
Stainless Steel for Corrosion Resistance
Nemaco offers corrosion-resistant grades of stainless steel for NEMA 6/6P enclosures. Common grades include:
- 304
- 304L (low carbon content)
- 316
- 316L (low carbon content)
You might ask:
- Which grade has better corrosion resistance?
- Which grade is more common and cost-effective?
Type 316 contains more nickel, molybdenum and chromium than type 304, offering superior corrosion resistance (and higher cost). Choose 316 for salt-water or chemical exposures; choose 304 when corrosion risk is lower to save cost.
Choosing between these details can be tricky—contact the Nemaco team today.
Aluminum Alloy Solutions
Nemaco designs and manufactures submersible waterproof control cabinets using:
- 5052 Aluminum
- 6061 Aluminum
5052-H32 and 6061 are lightweight, thermally conductive and corrosion-resistant—ideal for telecom, lift stations, traffic control and water/wastewater treatment. Aluminum enclosures are easier to install and dissipate heat effectively. Ask Nemaco about powder-coat finishes.
Powder Coat Surface Protection
To maximize longevity against harsh environments, Nemaco’s aluminum NEMA 6/6P enclosures are powder coated with UL-listed epoxy finishes in white, light grey, dark grey or black. Custom colors (hunter green, blue, yellow, orange, etc.) are available on request.
