CFR Roof™

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.
