About this file
The provided document is a technical reference for a 2.5" corrugated commercial/residential roofing panel system. Key details include:
The roofing panels have 211/3" coverage, a minimum 3:12 roof slope, and are exposed fastened. Finishes include MS Colorfast45, Acrylic-Coated Galvalume, and Bare Galvanized. The panels are available in 30, 29, 26, 24, and 22 gauge thicknesses, with corrosion protection ratings of AZ55, AZ50, G60, G90 or G100. The panels are UL rated for impact, fire resistance, and Texas Windstorm. The document provides technical specifications, section properties, and allowable uniform load details for the panel system.
The related federal contract opportunity is for the National Park Service in the Yukon-Charley River National Preserve to procure galvanized roofing materials. The solicitation is set-aside for small businesses, under NAICS code 332322 with a 500-employee size standard. Quotes are due via email, and the resultant award will be a firm-fixed price purchase order.

Overdriven fasteners will cause panel distortions.
Fasteners should extend 1/2" or more past the inside face of the support material.
Thick panels (ex. 18 ga) or supports (ex. 1/2" steel) may require predrilling of holes for screws.

1. Theoretical section properties have been calculated per AISI 2016 'North American Specification for the Design of Cold-Formed Steel Structural Members'.
Ixx and Sxx are effective section properties for deflection and bending.
2. Allowable load is calculated in accordance with AISI 2016 specifications considering bending, shear, combined bending and shear and deflection. Allowable load considers the 3 or more equal spans condition. Allowable load does not address web crippling, fasteners, support material or load testing. Panel weight is not considered.
3. Deflection consideration is limited by a maximum deflection ratio of L/180 of span.
4. Allowable loads do not include a 1/3 stress increase for wind.
