Super Span X

* Fy is 80-ksi reduced to 60-ksi in accordance with the 2007 edition of the North American
Specifi cation For Design Of Cold-Formed Steel Structural Members – A2.3.2.

NOTES:
1. All section properties are calculated in accordance with the 2007 edition of the North American
Specifi cation For Design Of Cold-Formed Steel Structural Members.
2. Ix is for defl ection determination.
3. Mx is allowable bending moment.

MATERIALS
Unless otherwise specifi ed, the exposed surfaces of all panels shall be either clear acrylic coated or factory painted GALVALUME®. GALVALUME® is a zinc-aluminum alloy coating
that is applied to the base steel material. Acrylic coated GALVALUME® shall have a Coating Class AZ55 (0.55 ounces (combined total of both sides) per square foot). Factory painted
GALVALUME® shall have a minimum Coating Class AZ50 (0.50 ounces (combined total of both sides) per square foot). GALVALUME® coated steel for panels shall conform to ASTM
A792, Structural Quality. The 26 gauge panel shall conform to Grade 80 (80 ksi minimum yield strength); the 24 gauge panel shall conform to Grade 50 (50 ksi minimum yield strength).
All material shall be ordered to a minimum decimal thickness. Minimum ordered thickness for coated steel products always includes the thickness of the coating.

PAINTED FINISH
All painted GALVALUME® shall be factory coated by a fi rm which coats coil products exclusively. The coater
shall be responsible for ensuring color consistency, paint fi lm hardness, and paint fi lm thickness. Each side of
the GALVALUME® will be coated with 0.2 mils baked-on primer before the color coating. The 26 gauge panel
shall receive a baked-on silicone polyester fi nish coat on the exposed side. The 24 gauge panel shall receive a
KYNAR 500® Fluoropolymer fi nish coat on the exposed side. Thickness of the fi nish coat will be a nominal 1.0
mils (including the primer coat). A baked-on straight polyester wash coat will be applied on the non-exposed
side. Thickness of the wash coat will be a nominal 0.5 mils (including the primer coat).

LIMITED MATERIAL WARRANTY
Specifi c conditions concerning each fi nish shall be covered in detail on the written warranty issued, on
request, with each order. Minimum roof slope – 1/2:12. GALVALUME® panels shall have a twenty-fi ve year
limited warranty providing that GALVALUME® panels will not rupture, fail structurally, or perforate within a
period twenty-fi ve years after shipment due to exposure to normal atmospheric corrosion. The clear acrylic
fi nish does not carry a warranty. The 26 gauge factory coated GALVALUME® panel shall have a thirty-year
limited color fi nish warranty from peeling and cracking, and a twenty-fi ve year limited color fi nish warranty
from excessive chalking and color change (fading). The 24 gauge factory coated GALVALUME® panel shall
have a thirty-year limited color fi nish warranty from excessive chalking and color change (fading), peeling and
cracking. The wash coat does not carry a warranty.

PANELS
Panel coverage will be 36” to the weather. Maximum panel length shall be 40’-0”. Where endlaps are required, they shall be a minimum of 4” and shall occur at a purlin. A roof installed
as listed in UL Construction No. 167 shall meet the requirements of Underwriters Laboratories standard UL 580 Class 90 for uplift resistance. All installations shall be in accordance
with standard industry practices. Before securing, all laps of roof panels shall be sealed with a continuous ribbon of tape sealant. A closure strip shall be installed at the eave. Panels
shall be secured to intermediate framing members with sheet metal screws at a maximum spacing of 12” on center. At endlaps, the maximum screw spacing shall be 6” on center.
Sheet metal stitch screws at a maximum of 20” on center shall be installed at sidelaps. The panel must not rest on the concrete foundation; the panel must sit 1/8” above the concrete.
Panels shall be furnished square cut.
