Tuff-Cast™ and Tuff Wall® insulated metal panels have a factory applied, hard aggregated fiber reinforced polymer coating called Tuff Cote®. Tuff Cote® finish offers an extremely durable, impact-and abrasion-resistant coating that withstands severe weather conditions.

Tuff-Cast™ is an exceptionally attractive insulated wall panel that provides the appearance of finished pre-cast concrete with a tilt-up look.

Tuff Wall® panels mimic a stucco-like finish that provides the masonry look that many designers and communities desire.

Unlike field-applied finished that are vulnerable to damp or cold weather during installation, Tuff-Cast™ and Tuff Wall® panels can be erected in virtually any weather conditions. The interior face of the panel is finished with an attractive Mesa profile and painted with a white polyester coating.

Notes:

  1. The Load Span Table above is based on Allowable Stress Design (ASD). For loads calculated based on ASCE 7-10 (LRFD), please refer to section 2.4.1 of ASCE 7-10 for the applicable load combinations using Allowable Stress Design.
  2. Based on CF-42 panel with 26 ga. Tuff-Wall/Tuff-Cast exterior and 26 ga. Light Mesa interior face (min Fy = 33 ksi). For 5″ and 6″ thick panels, the exterior face is 26 ga. Mesa.
  3. For connection FP1, CF panel clips are fastened to min. 14 gage steel with (2) ¼”-14 SDS Tek 3 at all supports. For 12 gage or thicker steel, #12-24 SDS Tek 5 may be used. In lieu of self-drilling screws, self-tapping screws may be used.
  4. The fastener pattern, FP2, FP3 & FP4, includes CF panel clip attachment plus 1, 2, and 3 Fabloks, respectively, at supports per panel width. Fab-lok spacing is 10.5″ o.c. from femaleedge of panel seam.
  5. The through fasteners (FP9) are as follows: #12-24 SDS in min 12 ga. steel; or ¼”-14 SDS in min 12 ga. steel; or ¼”-14 STS in min 14 ga. steel. 4 Fasteners per panel width @ max 8.4″ o.c.
  6. The through fasteners (FP10) are as follows: #12-24 SDS in min 12 ga. steel; or ¼”-14 SDS in min 12 ga. steel; or ¼”-14 STS in min 14 ga. steel. 5 Fasteners per panel width @ max 8.4″ o.c.
  7. Allowable positive or suction load is the lowest value of panel bending strength, shear strength,deflection limit and connection strength for each fastener pattern.
  8. 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 shearstresses and deflection limitation of L/180.
  9. The panel connection strength was determined from ASTM E1592 testing and the allowable loads are calculated with factor of safety of 2.
  10. The structural capacity of the purlins are not considered and must be examined independently.
