Nemaco’s Type 4X products have been designed and tested to meet the NEMA standards and selected enclosure product categories have been approved by UL.
The Type 4X rating per UL 50, 50E & NEMA 250 standards requires that equipment in the enclosure must be protected from ingress of heavy water spray in any direction. Also, prototype sample enclosures must endure and pass corrosion-resistance testing. Call Nemaco for more information about our quality test procedures for standard products and UL approval products. Both ferrous (stainless steel) and non-ferrous (aluminum) metals have distinct advantages and unique physical qualities that are ideal for many applications. Call Nemaco if you have any questions about materials and applications.
Enclosure Materials & Coating
Stainless Steel (304 / 316L)
Nemaco’s Type 4X products are designed and fabricated with the following corrosion-resistance metals: stainless steel and powder-coated aluminum. Both stainless steel and aluminum materials have ideal physical characteristics and advantages. Stainless steel has overall strength, durability and the premium grades of stainless steel (304 / 316L) offer superior levels of corrosion resistance against salt, acids, and other chemicals. In particular, the grade 316L stainless steel has more chrome molecules in the chemical composition and therefore it can provide more corrosion-resistant protection. Most engineers prefer to specify stainless steel for many electrical projects that require superior corrosion resistance.
Aluminum (5052 / 6061)
Nemaco offers Type 4X products in aluminum grades (5052/6061) to better serve customers that request lightweight enclosures and cabinets that have mild corrosion resistance. Most of the enclosures and cabinets are powder coated for better wear and corrosion resistance to marine environments or salt spray. Of course, the powder-coated enclosures look great! Many engineers, designers, and other techie guys like to specify powder-coated cabinets for electrical control systems and other applications.
Nemaco offers both stainless steel and powder-coated aluminum as solutions. Some customers prefer powder-coated aluminum instead of stainless steel. Aluminum has a much lower weight and therefore is much easier to transport to field locations and install by work crews. Also, aluminum has great heat transfer properties. Also, please note that it is easy to powder coat aluminum metal surfaces. And of course, powder-coated bonds (adheres) to aluminum easily.
Both ferrous (stainless steel) and non-ferrous (aluminum) metals have distinct advantages and unique physical qualities that are ideal for many applications. Call Nemaco if you have any questions.
