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 Vertical Seam
roof system. The floating clips for the Vertical Seam 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.
SYSTEM EXPANSION / CONTRACTION
Vertical Seam Clip
Vertical Seam panel clips - 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.
The following chart should be used to determine proper fasteners required for clip installation on the selected applications.
(See Fastener Selection Guide page 16 for other fasteners available.)
* Length of Deck Screw will vary depending on the total thickness of the rigid insulation and metal.
** Contact your local Metal Sales branch representative for more information (see pages 2 and 3).
