Full Name
ICC-ES AC541 – Acceptance Criteria for Steel Channel Slot Cladding Support Systems
Scope
ICC-ES AC541 outlines the acceptance criteria for evaluating steel channel slot cladding support systems used to attach exterior wall claddings, such as metal panels, to building structures. The primary goal is to ensure these systems provide adequate support, durability, and safety for the cladding while complying with relevant building codes and standards.
The evaluation process encompasses several aspects, including:
- Material properties: assessment of the steel channel’s mechanical properties, such as yield strength, tensile strength, and corrosion resistance, to ensure its ability to withstand structural loads and environmental conditions.
- Connection details: evaluation of the design and performance of connection elements, including brackets, fasteners, and anchors, to ensure secure attachment of the cladding to the support system and the building structure.
- Structural performance: assessment of the overall structural performance of the system, including its ability to resist wind loads, seismic forces, and other applicable loads, as per the building code requirements.
- Installation methods: evaluation of the recommended installation procedures to ensure proper assembly and functionality of the support system.
- Code compliance: verification that the steel channel slot cladding support system, its components, and installation methods comply with relevant building codes and standards, such as the International Building Code (IBC).
By meeting the criteria outlined in AC541, manufacturers can obtain an evaluation report from ICC-ES, which can be used to demonstrate code compliance and gain approval for use in building projects.
