True or False: A standing seam is never riveted, bolted, or button punched.

• A. True
• B. False
• C. Sometimes
• D. Not applicable

Answer: (B)

Standing seam refers to the type of seam that locks adjacent panels together and often hides fasteners, giving a clean look with good weatherproofing. But that doesn't mean no fasteners are ever used. In some installations, especially retrofit projects, edge details, or certain climate or structural requirements, panels or clips may be attached with rivets, bolts, or through-fasteners. Button-punched methods are another older or specialty way fasteners can be incorporated. So the statement is false: a standing seam can be riveted, bolted, or button punched in some configurations.
