The Industry Standard in Industrial Enclosures

Hoffman mild steel enclosures have set the standard for industrial electrical protection for over 75 years. When engineers and electricians think of quality industrial enclosures, Hoffman is invariably the first name that comes to mind. This reputation for excellence, quality, and attention to detail has made Hoffman the preferred industrial enclosure solutions provider worldwide.

Superior Construction and Finish

Hoffman mild steel enclosures are manufactured from high-quality carbon steel using precision forming and welding techniques. Continuously welded seams provide structural integrity and environmental protection. The standard ANSI 61 gray powder coat finish resists scratches, chips, and corrosion, maintaining an attractive appearance throughout the product's service life. Optional finishes, including white and custom colors, are available for specific applications.

NEMA Ratings for Every Application

Mild steel enclosures are available in a comprehensive range of NEMA ratings to meet diverse application requirements:

  • NEMA 1 - General purpose indoor protection
  • NEMA 3R - Outdoor protection against rain and sleet
  • NEMA 4 - Watertight protection for indoor/outdoor use
  • NEMA 12 - Industrial dust-tight and drip-tight protection
  • NEMA 13 - Oil-tight protection for manufacturing environments

Cost-Effective Protection

Mild steel enclosures deliver outstanding value by combining Hoffman's renowned quality with economical material costs. For indoor industrial applications not requiring special corrosion resistance, mild steel provides the ideal balance of performance and price. The durability of Hoffman's powder coat finish means these enclosures maintain their protective capabilities and appearance for decades of service.
