Jonathan Hunt from The Fellowship Round Rock in Round Rock, Texas brings these columns of light-weight plastic roofing.
They accomplished the look by hanging 12-foot corrugated plastic roofing panels from their ceiling. Each panel was 12-feet long except the shorted panels that were 6-feet long. They held them all together with black zip ties. Then used zip ties and chains to connect them to the ceiling. Then the back panels were screwed straight into the wall.
They picked up the panels at a Home Depot for about $400 total, hung them, and pointed LED Thin Par 64s at them.
