MESA
The Metl-Span Striated Mesa insulated wall panel is an attractive and economical alternative to typical flat wall panels. The exterior face is lightly profiled with narrow longitudinal striations and exhibits a virtual flat appearance from a short distance away. The Striated wall panel is an exceptional value combining the aesthetics of a flat wall panel and high insulation ratings of a polyurethane core.
Note: Not intended for exterior walls on cold storage buildings.

attributes & advantages
Metl-Span’s Mesa insulated wall panel with a urethane foam core have a standard FM Class 1 approval and offer the best insulating values available today.
Panels are lightweight and quick to install, significantly reducing construction time.
A double tongue-and-groove offset side joint permits concealed fastening.
Consistent insulating values are achieved with built-in thermal breaks, saving energy.
The metal and foam composite construction creates a rigid panel far stronger than the individual parts. This increases the span capability of the panels and reduces the need for secondary structural steel components.

- Based on CF-36 and CF-42 panel with 26 ga. Santa Fe exterior & 26 ga. Light Mesa interior faces (min Fy=33 ksi).
- For pattern FP1, CF panel clips are fastened to minimum 14 gage steel with (2) 1/4″-14 SDS Tek 3 at interior supports and (1) 1/4″-14 SDS Tek 3 at end supports. For 12 gage or thicker steel, #12-24 SDS or 1/4″-14 SDS Tek 5′s may be used. In lieu of self-drilling screws, self-tapping screws may be used.
- Fastening patterns FP2, FP3, FP4, and FP5, includes CF panel clip attachment plus 1, 2, 3 or 4 Fabloks, respectively, at supports per panel width. Fab-lok spacing is 10.5″ OC from the female edge of the panel seam.
- The through fasteners (FP9) are as follows: #12-24 SDS in min 12 ga. steel; or #1/4-14 SDS in min 12 ga. steel; or #1/4-14 STS in min 14 ga. steel. 4 Fasteners with 5/8″ neoprene bonded washers per panel width @ max 8.4″ OC.
- The through fasteners (FP10) are as follows: #12-24 SDS in min 12 ga. steel; or #1/4-14 SDS in min 12 ga. steel; or #1/4-14 STS in min 14 ga. steel. 5 Fasteners with 5/8″ neoprene bonded washers per panel width @ max 8.4″ OC.
- The allowable suction load is the lowest value of panel bending strength, shear strength, deflection limit and connection strength for each fastening pattern.
- Allowable loads based on panel stress and deflection design criteria are derived from ASTM E72 structural testing and calculated with factor of safety of 2.5 for bending stress, 3.0 for shear stresses and deflection limitation of L/180.
- The panel connection strength was determined from ASTM E1592 testing and the allowable loads are calculated with the factor of safety of 2.
- The structural capacity of the girts are not considered and must be examined independently.
- Consult Metl-Span for recommendations on panel profile and gage suitable for thermal stresses.
