Nemaco manufactures with the highest quality grades of different materials for NEMA rating enclosures and IP rating standard enclosures. We offer carbon steel, aluminum, 304/316 stainless steel, and fiberglass. Each material has different characteristics. Therefore, consider to advantage and disadvantage by comparing them, can make us choose the right material suitable to a particular environment. In addition, we also offer powder coated carbon steel and aluminum for corrosive protection.

We fabricate excellent electrical enclosures adherence NEMA rating standard, to ensure our customer will get the performance and reliable enclosures.


Carbon steel enclosures are the strongest electrical enclosures because carbon is the strongest material. There are some advantage and disadvantage compare to other types of materials. Carbon steel electrical enclosures are suitable for general indoor or outdoor use. It is considered to be one of the most widely used steel metals.

Aluminum enclosures (Aluminum Alloys) yield cost-effective products due to the low melting point. It has a high level of silicon, therefore it is good for casting characteristics. These material enclosures give a lightweight and corrosion resistance characteristic. However, they generally have lower tensile strengths than stainless steel and carbon steel. Read for more information about our aluminum enclosures (we offer both 5052 aluminum and 6061 aluminum).

Nemaco provides both 304 and 316 stainless steel enclosures for customers. We are manufacturing safety rated electrical enclosures designed for comprehensive indoor and outdoor using these materials. Characteristics of stainless steel enclosures are corrosion resistant, and strong. However, it produces a lot of weight, customers need to consider this factor for your applications. We specialize in manufacturing customed enclosures, widely enclosure sizes, add-on options, and enclosure types. Click for more information about our 304 and 316 stainless steel enclosures

Nemaco can offer FRP enclosures in standard materials, FR (flame/fire retardant) and HT (high temperature) plastic resin formulations. This type of material produces corrosion resistant to salt water and many chemicals, as well as electrically non-conductive materials and thermal insulators.
