Commercial Clips and Cleats
The concealed engineering behind every standing seam metal roof. How clip and cleat systems manage thermal movement, resist wind uplift, and maintain weathertight integrity.
What Is the Difference Between Clips and Cleats?
Clips attach standing seam panels to the structural deck along the panel runs. Cleats secure panels at edges, ridges, and transitions. Both are concealed within the seam, providing attachment without roof penetrations. The selection and spacing of clips and cleats is engineered for each project based on building dimensions and material specifications.
How Do Fixed and Floating Clips Work Together?
Fixed clips anchor a panel at one point, while floating clips allow the panel to slide as it expands and contracts with temperature changes. A typical installation uses fixed clips at the top of each panel run and floating clips throughout the remainder. This combination prevents panel buckling while maintaining structural attachment.
How Is Clip Spacing Determined for Commercial Projects?
Clip spacing is calculated using the building's wind exposure category, panel gauge and profile, and the required wind uplift rating. Perimeter and corner zones require closer spacing than field areas. The Metal Roof Pros provides engineered clip layout drawings for every commercial project.
What Happens When Clips Are Improperly Installed?
Improper clip installation causes panel oil-canning, seam disengagement, and premature system failure. Common errors include using the wrong clip height, mixing manufacturer clip systems, over-driving fasteners, and ignoring thermal movement requirements. These errors are invisible until the roof fails under wind or thermal stress.
