The patented ZEUS-Shield Metal Roof System consists of three roof panel profiles.
- ZS-T24 predominately for low pitch roof applications up to 3/12 pitch.
- ZS-A16 Architectural designed series for steeper single or double sloped
rectangular areas.
- ZS-A18 Architectural designed series for steeper single or double sloped
rectangular areas.
The patented ZEUS-Shield Metal Roof System has earned the following recognized certifications and listings:
- Underwriters Laboratories UL-90 Classification Construction No. 506
- Factory Mutual Class 1-90 and 1-165 Listing
- Corps of Engineers CEGS 07416 uplift Test
- ASTM E 1592 Uplift Test (three tests each span each gauge)
- ASTM E 1680 Air Infiltration
- ASTM E 1646 Water Leakage
The ZEUS-Shield Metal Roof Panel System has been tested and certified by independent testing agencies and laboratories and achieved the loads and listings shown in the Underwriters Laboratories Inc. chart below:

ASTM E 1680 Air Infiltration all seams 24" wide panels = .0005 CFM/sq.ft
ASTM E 1680 Air Infiltration all seams 16" wide panels = .005 CFM/sq.ft
ASTM E 1646 Water Leakage all seams 16", 18" & 24" wide panels = None at 12 psf
- The above tabulated loads are generated from ASTM E-1592 testing
- Design loads contain a safety factor of calculated per AISI
- COE design load contains a 1.65 safety factor per COE 07416
- Allowable wind uplift loads have not been increased by 33% as allowed by some codes when wind load controls
ZEUS-SHIELD roof system and its components are covered by US Patent numbers 5,692,352 - 5,737,894 - 6,301,853 B1 and other patents pending.
