Nucor "CFR"™ Standing Seam Roof System |
The
Nucor "CFR"™ system
is a functional roof specifically designed for low
slopes. Our roof has been extensively tested to
ensure the highest level of performance for weathertightness
as well as structural integrity. The panels have
been tested and approved by Factory Mutual® and Underwriters Laboratories® for wind uplift
as well as hail and fire resistance. Nucor offers
flexible options which provide a number of cost
effective design solutions.
State of the Art Clip Design |
 |
The Nucor CFR™ Clip is a patented clip designed to provide a high degree of flexibility while maintaining excellent lateral purlin support.
Steel roof panels expand and contract with changes in temperature. The design of our patented clip accommodates these thermal movements by sliding back and forth with the metal. The result is a roof connection that maintains the highest degree of system performance while allowing for movement of the roof panels. |
