NOTES:

1.     Stress loads are total loads limited by maximum bending stresses based on calculated properties
2.     Deflection loads are limited by a maximum deflection ratio of L/240 or the maximum bending stress.
3.     To obtain uplift loads due to wind, multiply tabulated values by 1.333.
4.     All panels are Fy = 50 KSI.
5.     All calculations for the properties of Pro Seam panels are calculated in accordance with the 1968 edition of Specifications for the Design of Light Gauge Cold Formed Steel Structural Members, published by the American Iron and Steel Institute (AISI).

All steel substrates are manufactured in accordance to ASTM A446 Specifications. Protective coatings shall be either Galvanized G90, 1.25 oz/sq. ft., meeting ASTM A525; or Galvalume AZ55, .55 oz/sq. ft., meeting ASTM A792 Specifications.

1. Section properties are calculated in accordance with the 1986 AISI Cold Formed Steel Design Manual, 1989 Addendums.
2. Section properties are based on base material thickness without protective coatings.
3. Panels with purlin bearings legs are available in Rib-12 Galvalume™ only.
4. All steel substrates are manufactured in accordance to ASTM A446 specifications. Protective metallic coatings shall be galvanized, G90, 1.25 oz/sf, meeting ASTM A525 or Galvalume™, AZ55, 0.55 oz/sf, meeting ASTM A792 specifications.
5. Organic paint coatings shall be silicone polyester equal to Ceram-A-Star™ 950 and shall meet ASTM G23, G26 and B117.
