(Specification)Standard Specification for Metal Canopy Systems
Standard Specification for Metal Canopy Systems
ABSTRACT
This specification applies to metal canopy systems including structural framing, canopy deck system, drainage system, fascia panels, accessories and trim, and canopy concrete foundations and accessories. It specifies the requirements for pre-engineered metal canopy systems, manufacturer's standard mutually dependent components, and assemblies that form a pre-engineered overhead canopy system to enhance safety and security. The pre-engineered overhead canopy system shall be capable of withstanding required design loads per the International Building Code as adopted or modified by local jurisdictions, thermally induced movement, and exposure to weather without failure. Primary structural frame design shall include fixed-base columns capable of transferring moments and forces into foundations, as well as roof purlins, main frame beams, and tube columns, plus secondary framing, canopy deck and fascia panels, and accessories. The requirements also cover submittals; delivery, storage, and handling; coordination; and warranty. Erection of structural steel, canopy deck panel installation, fascia installation, accessory installation, and cleaning and protection are also covered by this specification.
SCOPE
1.1 This specification includes the following:
1.1.1 Structural framing,
1.1.2 Canopy Deck System,
1.1.3 Drainage system,
1.1.4 Fascia panels,
1.1.5 Accessories and trim, and
1.1.6 Canopy concrete foundations and accessories.
1.2 Units—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.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
