100% QUALITY CONTROL

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.

TESTING REQUIREMENT

We test all waterproof enclosure designs to pass NEMA 6 and 6P criteria of UL50, 50E adherence NEMA 250 rating, which enclosures and boxes need to give protection against water in submersion circumstance under 6 ft (1.8 m) of water for 24 hours and must be result in “NO WATER” get inside.

Stainless Steel for Corrosion Resistance

Nemaco offers corrosion resistant grades of stainless steel for the NEMA 6 / 6P Enclosure categories. Here are the most common grades of industrial stainless steel available on the market for customers.

304
304L (low carbon content)
316
316L (low carbon content)

So you might be curious and you want to ask these questions.

Which grade of stainless steel has better corrosion resistance?
Which grade of stainless steel is more common and cost less?

Here is the key difference between the stainless grades: type 316 has typically more nickel, molybdenum and chrome than type 304. Therefore, the grade 316 stainless steel has more corrosion resistance and therefore grade 316 costs more than grade 304.

Choose grade 316 if your enclosure application will have exposure to salt or chlorides. For example, cabinets near the salt water oceans or near a chemical plant, then typically engineers prefer to specify 316 stainless steel for its’ benefit of longer lasting corrosion resistance and the overall better long term value to avoid equipment replacement costs. However, if corrosion is not a strong concern for your application, then the choice of 304 stainless steel would be a better fit and provide cost savings.

Aluminum Alloy Solutions

Nemaco design and manufactures submersible waterproof control cabinets. Typically, the company uses the following grades of aluminum.

5052 Aluminum
6061 Aluminum

Aluminum 5052-H32 and 6061 are excellent materials to use in industrial applications such as; telecommunication cabinets, lift stations, traffic control enclosures and water & waste water treatment facilities. Also, aluminum materials can be used in some submersible applications.

The advantage of aluminum waterproof cabinets are light weight and commonly much easier to field install. Aluminum offers great heat transfer dissipation due to its excellent thermal properties. Also, aluminum can offer some corrosion resistance when compared to ferrous carbon steel. Ask Nemaco about powder coating options.

Powder Coat Surface Protection

To ensure that all aluminum waterproof enclosures and cabinets have much more longevity against harsh environmental weather conditions and water submersion, Nemaco’s aluminum NEMA 6 / 6P enclosures are powder coated with UL Listed coatings. We offer a range of powder coat colors: white, light grey, dark gray and black. Custom colors are available on request: for example … hunter green, blue, yellow or orange.
