Model 790CW 

rolling steel sheet door

When your project requires a door that can handle high wind load conditions, yet is attractive, versatile and economical, the Model 790CW fits the job. This rolling sheet door (790) is rated for a design pressure from 22/-22psf (for a 20’0” wide door) to 41/-41psf (for a 10’0” wide opening), and can be built up to 16’0” tall. The 790CW is available in 11 standard colors.

Fabricated of high strength, 26-gauge galvanized steel curtain sections, 14-gauge universal guides, and steel bottom bar angle, the 790CW is a strong and durable door. With quick-connect components, universal through-hole guide design, and unique curtain profile and stepped counterbalance rings that minimize nesting, the 790CW is designed for fast installation, smooth operation and low maintenance, too.
