Stainless Steel Mesa and Light Mesa Wall Panel

product-stainlessmesalightmesa

  • Description
  • Advantages & Attributes
  • Material Specifications

The Metl-Span CF Stainless wall panel has a highly reflective surface and the same attractive profile as the Metl-Span CF Mesa wall panel. The panel is suggested for use in areas where the faces are exposed to high-pressure wash-down and chemical cleaners. Note: Use of chlorides for cleaning may cause corrosion of stainless steel surfaces if not thoroughly rinsed off.

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.

Uses and Applications

In new and retrofit construction, Mesa 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 Warehoues
  • All Controlled Environment Buildings Where Temperature Control and Insulation Values are Critical

  • 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, repsectively, 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 Building Systems for recommendations on panel profile and gage suitable for thermal stresses.

  • Refer to the allowable connection load chart, for suction loads, which controls support spacing requirements.
  • Allowable positive load is the lowest value of panel bending strength, shear strength & deflection limit.
  • 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.

  • Based on CF-30, CF-36 and CF-42 panel with 26 ga. Light Mesa exterior & 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 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.

  • Based on panels with 26 gage exterior and 26 gage interior face (min Fy = 33 ksi) for single span condition.
  • Allowable span is the lowest value of panel bending strength, shear strength and deflection limit.
  • The spans based on panel stress and deflection design criteria are derived from E-72 structural testing.
    The allowable loads are calculated with a factor of safety of 2.5 and 3.0 for bending and shear stresses, respectively
    and deflection limitation of L/120.
  • The structural capacity of support members and panel attachment to the support members are not considered
    and must be examined independently.
IMPORTANT NOTES:
  • Deflection caused by temperature differential induced thermal bow is not addressed in the above table
    and may result in allowable spans that are less than the spans listed above and may require the use of heavier 24 or 22 gage panel
    facings at added cost. Except for self-supporting the dead weight of the panel, partition wall panels are non-load bearing. Ceiling
    panels must be supported from the structure above or by an internal support structure. Panel skins must be captured at both ends of
    the panel by supporting members designed to support reaction pressures from a 5 psf interior pressure. CF-42 = 42″ wide. CF-45 =
