A polycarbonate U channel is a long, thin profile shaped like the letter “U” made from polycarbonate, a type of plastic known for its strength, clarity, and weather resistance.
They are commonly used for capping the ends of polycarbonate multiwall sheets, which are panels with hollow chambers that are used for roofing, greenhouses, and other applications. U channels help to keep dirt, insects, and moisture out of the flutes of the multiwall sheet, and they also improve the finished look of the installation.
