Sectional Steel Doors Model C-20

Wayne Dalton Models C-20 & CX-20 commercial steel sectional doors are designed, engineered, and constructed to assure smooth, efficient operation and to save installation time and effort.

These steel sectional doors feature pre-finished 20-guage hot-dipped galvanized sections roll-formed to a full 2” thickness for ultimate strength and durability. Optional insulation consists of 1-5/16" expanded polystyrene which provides an R-value* of up to 7.64 and a U-value as low as 0.13.

Model CX-20 incorporates tongue-and-groove construction with self-forming rivets clinched to face and rails for superior stability throughout the door. Both steel and Polylaminate backer choices are available to ensure the CX-20 is well suited for a wide-range of commercial applications.

Model C-20’s unique 2” x 3” box-stile design, plus tongue-and-groove construction, adds vertical stability and strength. Stiles are continuously-bonded to the skin surface with high-strength adhesive, resulting in the strongest possible unit. The surface is ribbed for added strength. Independent tests show that these doors are significantly stronger compared to leading competitors.
