NEMA 1, 2, 3, 3R TIGERBOX ENCLOSURES
The NEMA 1, 2, 3, 3R Tigerbox Enclosures are available in carbon steel and EG (electrogalvanized) carbon steel. Special aluminum and 304/316 stainless steel materials are available as an option. The carbon steel and EG enclosures are always cleaned, degreased and then phosphate rinsed to prevent rust corrosion before electrostatic powder coating and/or wet painted. Only "top quality" powder coating and wet paint materials are used. Most of the Tigerbox enclosure coatings are UL listed. Just top quality and tough stuff NEMA boxes.  Sorry, we do "not" use cheap quality materials.

Depending upon the NEMA enclosure style, NEMA listing (if applicable), application and/or any special requirments by a customer, then the enclosures may be fastened by screws, pop-rivets, bolts and/or welded construction. Most of the time, the exterior mtg brackets (if applicable) are welded to enclosure for additional strength.

UL listed gaskets are installed on some Tigerbox 3R Style NEMA Enclosures as an option.

NEMA 4 TIGERBOX ENCLOSURES
The NEMA 4 Tigerbox Enclosures are made from carbon steel (or EG), welded (including stitch and/or plug welding for additional strength) and then cleaned, degreased. All the enclosures are phosphate rinsed to prevent rust corrosion before powder coating. Then the powder coatings are applied by electrostatic spray. Customers may choose from many Super Tiger Colors. And ... also wet paint coatings and many textures are available.

Surface finish options include: our super nice grain finish; and our lower cost 2B (no finish) and/or nice orbital finish. All the enclosures are passivated. Passivation: Nitric acid and/or phosphoric acid electrolysis to reduce residual corrosion and repair the stainless steel surface corrosion resistance on welded sections (corners, edges and mtg brackets). Many of our NEMA enclosures we use UL listed gaskets and they gaskets are installed per UL requirements.   These enclosures "may not" be considered UL listed.  But the most of the NEMA enclosures have "off the shelf" or UL listed gaskets.
