To whom it may concern: Moment Engineering + Design has performed a comprehensive structural review of the Cornell Iron Works Rolling Overhead Door product lines described above, for typical installations in the State of Florida. Statement of Compliance: When constructed and installed per the conditions and design criteria described herein, the Rolling Overhead Door product lines described above are compliant with applicable sections of the design reference documents noted below. Design Reference Documents:  2020 Florida Building Code  2018 International Building Code  FBC Test Protocols TAS 201, 202, and 203  ASCE/SEI 7-16 – Minimum Design Loads and Associated Criteria for Buildings & Other Structures  Proprietary load test data and evaluation (see technical documentation below)  Proprietary sections and materials properties as noted Overview: The doors described in this report consist of a continuous door panel made of interlocking cold-formed steel door slats suspended from an overhead drum roller. The drum roller serves to store the curtain in a coiled configuration when the door is opened. Note that evaluation of the drum roller assembly is not included in this report. The sides of the curtain are constrained from lateral movement along their vertical edges by steel guides attached to the door jambs. This constraint provides resistance to lateral wind forces. Various guide configurations are used for the different door styles included in this report. The lateral wind forces are transferred from the curtain to the guides and then through the attachment elements to the door jamb. The door jambs are part of the main wind force resisting system of the existing structure and are usually constructed of steel, concrete, or concrete masonry units. Resistance of existing structures to design loads from proposed overhead rolling doors is not included in the scope of this analysis and should be evaluated by a registered design professional where required by the authority having jurisdiction. Details of door assembly and associated components appear in the following documents: Table 1.

Door Slats: CP0020 Slats: All non-insulated doors covered in this report use a CP0020 slat with a minimum thickness of 0.0220” (0.0405” thickness for perforated slats). The nominal dimensions of the formed slats are approximately 2- 5/8” height by ¾” depth for all CP0020 slats. CP0001 / CP0651 Slats: All insulated doors covered by this report use a CP0001 or CP0651 slat. The minimum thickness of the front portion of these slats is 0.0220”. The minimum thickness of the back portion of these slats is 0.0220”. The dimensions of the formed slats are approximately 3” height by 1” depth for all CP0001 and CP0651 slats. The CP0001 is injected with polyurethane foam insulation. The CP0651 is filled with mineral wool insulation. Slats may be manufactured using galvanized steel sheet, ASTM A653 HSLAS, grade 40; ASTM A653 HSLAS-F, grade 40; or ASTM A653 structural steel, grade 40. Stainless steel slats may use Type 201, 304, 316, or 430 alloys with minimum specified yield strength of 40 ksi. A rational analysis was made on each tabulated door to determine the structural requirements of the curtain, guide, windlock attachments, and guide attachments for each of the indicated design wind pressures. A comparison with test results was made to substantiate analysis results. I. Door Tests with Non-Insulated Slats 1.
