Our Aluminum Columns are completely maintenance free and load bearing. We offer so many designs and various combinations of caps, bases & colors. They come fluted or smooth with seams that are hardly detectable. All widths and heights are available. They are structural and can be wrapped around existing support beams. Once again, like any home improvement - there are hundreds of manufacturers - the columns made for STOOP-IT are proven and have been used all over Long Island both in Nassau & Suffolk Counties with out a complaint. Can't beat that!
