(Specification)Standard Specification for Structural Standing Seam Steel Roof Panel Systems
Standard Specification for Structural Standing Seam Steel Roof Panel Systems
ABSTRACT
This specification covers the design, construction, and weatherability of structural standing seam steel roof panel systems. It includes performance requirements for the following elements only: panels, concealed panel clips, panel/clip anchorage, and panel joint sealers. Panel material shall be a hot dip metallic coated product in accordance with one of the following commonly used materials: aluminum-, aluminum-zinc alloy-, zinc-, or zinc-5% aluminum alloy metallic-coated sheet steel. The roof system shall be designed for specified design loads and thermal effects without causing seam separation, permanent panel buckling, or weather-tightness loss. Deflection and serviceability shall be accounted for in the panel system for structural integrity. Static and uplift index tests shall be performed to determine the roof's load capacity. Standing seam roof panel systems shall be installed in accordance with the system design requirements.
SCOPE
1.1 This specification covers the design, construction, and weatherability of structural standing seam steel roof panel systems. It includes performance requirements for the following elements only: panels, concealed panel clips, panel/clip anchorage, and panel joint sealers.
Note 1—These systems are used on both low-slope and steep-slope roof applications. They also are used with or without an underlying deck or sheathing.
1.2 The objective of this specification is to provide for the overall performance of the structural standing seam steel roof panel system as defined in 3.2.6 during its service life in order to provide weather protection, carry the specified design loads, and allow proper access over the roof surface in order to provide for periodic maintenance of equipment by the owner.
1.3 In addition to structural, the specifier shall evaluate other characteristics beyond the scope of this specification that affect the final choice of roof construction. These include, but are not limited to, functional, legal, insurance, and economic considerations. See Appendix X1 for specifier's checklist.
1.4 The specification is not intended to exclude products or systems not covered by the referenced documents.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.6 The text of this specification contains notes and footnotes that provide explanatory information and are not requirements of this specification.
