IMP-Tuff Wall®

Tuff Wall® is an exceptionally attractive stucco-like insulated metal wall panel that exhibits the natural beauty that many designers and owners prefer. The exterior stucco-like surface of the panel is a hard aggregated fiber reinforced polymer coating created with the factory applied Tuff Cote® finish system. Tuff Cote finish offers an extremely durable impact and abrasion resistant coating that withstands severe weather conditions.

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

  • The masonry look of stucco with the efficiency of an insulated metal panel
  • The field-tested and proven Tuff Cote technology
  • A durable finish that is highly resistant to impact and abrasion
  • A 10-year limited warranty

The stucco and precast textures conform to the aesthetic demands required by many communities and business developments.

IMP Tuff Wall Material Specs

CF-42 TUFF WALL® WALL PANEL ALLOWABLE CONNECTION LOAD

  1. Based on CF-36 or CF-42 panel with 26 ga. Tuff Wall exterior & 26 ga. Light Mesa interior faces (min Fy=33 ksi).
  2. 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.
  3. 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 female edge of panel seam.
  4. 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.
  5. 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.
  6. Allowable suction load is the lowest value of panel bending strength, shear strength, deflection limit and connection strength for each fastening pattern.
  7. 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.
  8. The panel connection strength was determined from ASTM E1592 testing and the allowable loads are calculated with factor of safety of 2.
  9. The structural capacity of the girts are not considered and must be examined independently.
  10. Consult Metl-Span for recommendations on panel profile and gage suitable for thermal stresses.

TUFF WALL® WALL PANEL ALLOWABLE POSITIVE LOAD

  1. Based on CF-36 or CF-42 panel with 26 ga. Tuff Wall exterior & 26 ga. Light Mesa interior faces (min Fy = 33 ksi).
  2. Refer to the allowable connection load chart, for suction loads, which controls support spacing requirements.
  3. Allowable positive load is the lowest value of panel bending strength, shear strength & deflection limit.
  4. 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.
  5. The structural capacity of the girts are not considered and must be examined independently.
  6. Consult Metl-Span for recommendations on panel profile and gage suitable for thermal stresses.
