Industry Standards for Appearance

Guest User
On a preengineered metal building, with a standing seam metal roof. What is the industry standard for how far out of alinement can the centerline of seam be, before it has to be corrected? i.e. 1/2" in 20 feet, 3/8" in 40 feet?

This question may be better answered by contacting MBMA, the Metal Building Manufacturers Association. I'm sorry. I don't think I can help you.
