I recently had a discussion with a friend of mine who is in commercial construction. Typically he builds using long spans and vast open areas. He does occasionally need to use some curved soffits and arches. He admits that he doesn't like to hire wood framing contractors just to do the curves. He also admitted that he assumed he could not use our product. Here are some pictures for you Scott. You can indeed use our product in steel construction with all the flexibility of standard stick construction.
