Steel roofing panels are subject to dimensional changes after installation due to exposure to varying temperatures. The greatest
influence is solar energy. Steel roofing absorbs various amounts of heat depending upon color, finish, angle of exposure, and time
of exposure.
The relationship of ambient temperature to building structural temperature must be considered when designing a Clip-Loc roof
system. The clips for the Clip-Loc panels are designed for expansion and contraction of the panels in the longitudinal direction.
Lateral expansion and contraction is accommodated by the configuration of the panel cross section and causes negligible panel
movement.
When the total length of panel run exceeds the capability of the clips to accommodate the thermal movement, expansion joints
must be designed into the structure.

Clip-Loc Clip
Clip-Loc Panel Clip - Clips are placed along the male leg of each panel prior to installing adjacent panels. Design wind uplift
must be considered for proper clip spacing.
* Length of Dekfast will vary depending on the total thickness of the rigid insulation and metal (see page 17).
** Based on UL580. Subject to project loading requirements, closer clip spacing may be required. Contact your local
Metal Sales branch representative for more information (see pages 2 and 3).
