  • Material Specifications
  • Load Span Tables

CF Fluted wall panel provides bold vertical lines complimentary to almost any commercial or industrial building. Inverted ribs in the profile enhance the high-tech industrial look. The CF Fluted wall panel is the recommended profile for the exterior of cold storage buildings.

 

In new and retrofit construction, the panels function as walls, ceilings and roofing for cooler, freezer and food processing buildings. They are ideally suited for:

Cold Storage

  • Cooler Buildings
  • Freezers
  • Food Processing Buildings
  • Dry Goods Warehouses
  • All Controlled Environment Buildings Where Temperature Control and Insulation Values are Critical

  • Based on CF-42 panel with 26 ga. Flute exterior & 26 ga. Mesa interior face (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 female edge of 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.
  • 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 factor of safety of 2.
  • The structural capacity of the girts are not considered and must be examined independently.
  • Consult Robertson for recommendations on panel profile and gage suitable for thermal stresses.
