Highest Roof Value Through Highest Wind Load Applications
The Zeus Shield system is specified to ZONE III (highest wind load) seaming criteria for the entire roof area. This 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 a variety of wind load zones by either one or 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 more 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.
