Find the Right Finish for Your NEMA 13 Enclosure
Although some companies may provide the option to order NEMA 13 enclosures in polycarbonate or ABS plastic, Bison Profab exclusively recommends reliable metal fabrication. Plastic does not match the durability and dependability of our high-quality aluminum, stainless steel and steel.
Stainless Steel
Stainless steel is a premium option that provides excellent corrosion resistance. At Bison, we craft your enclosure from your selected type and gauge of stainless steel to meet NEMA 13 rating requirements.
Aluminum
Aluminum resists rusts and other forms of corrosion, ensuring the longevity of your electrical enclosure. Due to its lightweight nature, aluminum is easy to install in your indoor facility. Bison uses aluminum alloys to build enclosures that excel in harsh, high heat, high wear environments.
Carbon Steel
Carbon steel is a resilient and heavy-duty material, perfect for enclosures at risk of damage from impacts. Bison Profab makes NEMA 13 enclosures from cold-rolled carbon steel in order to help meet your thickness and flatness requirements.
Steel provides heavy-duty protection for enclosures at risk of any impacts. Your steel electrical enclosure can be made corrosion resistant with a coated finish.
