  • Description
  • FW-120 – Properties
  • Allowable Uniform Loads In Pounds Per Square Foot

The FW-120 panel is a concealed fastener wall and liner panel that provides a flat appearance. FW-120 is commonly used for architectural, commercial and industrial markets. The heavy gauge offering provides for large spanning capabilities, particularly in composite wall applications. FW-120 is available in a flat profile with one bead or two beads.

Air Infiltration and Water Penetration

The FW-120 Panel has been tested by a certified independent laboratory in accordance with ASTM test procedures for Air Infiltration and Water Penetration at the sidelap. Test results show no air leakage at 1.57PSF and no water penetration at 6.24PSF differential pressure.

Allowable Uniform Loads Notes:
  1. Strength calculations based on the 2012 AISI Standard “North American Specification for the Design of Cold-Formed Steel Structural Members.”
  2. Allowable loads are applicable for uniform loading and spans without overhangs.
  3. POSITIVE WIND LOAD capacities are for those loads that push the panel against its supports. The applicable limit states are flexure, shear, combined shear and flexure, web crippling at end and interior supports and a deflection limit of L/60.
  4. The weight of the panel has not been deducted from the allowable loads.
  5. THE ABOVE LOADS ARE NOT FOR USE WHEN DESIGNING PANELS TO RESIST WIND UPLIFT.
  6. The use of any accessories other than those provided by the manufacturer may damage panels, void all warranties and will void engineering data.
  7. This material is subject to change without notice. Please contact Robertson for the most current negative wind loads.
