The Zeus Shield system is specified to ZONE III (highest wind load) seaming requirements for the entire roof area. This preference ensures the total roof area is completed with the same seaming method for maximum uplift performance. There is no need to change purlin spacing, panel thickness or to install external clips over the seam. This results in a lower overall cost of both materials and installation man-hours.
- Zone I: LOWEST LOAD - main field of the roof (about 80% of total roof surface)
- Zone II: INERMEDIATE LOAD - area around the perimeter of the roof (about 15% of total roof surface)
- Zone III: HIGHTEST LOAD - at each corner of the roof (about 5% of the total roof surface)
Other roof systems accommodate these various wind load zones by either
one of a combination of the following: reduced purlin spacing at higher
zone roof areas, thicker panel material in these areas, reduced panel
width or exterior clamps over the panel seams. All of these conventional
methods call for increased materials, inconsistent structural spacing
and added complexity during installation.
Our patented roof system accommodates all three roof zones - simply and
efficiently - by executing one of two seaming shapes. Each shape is formed
in the field after the roof panels have been installed, meeting precise
roof wind loading requirements for each roof zone without added materials
or altering panel/purlin placement.
