Our Columns are architecturally proportioned columns manufactured from Fiberglass-Reinforced Polymer (FRP) – the most advanced construction material in the world. With Flame Guard™, our Columns pass an industry test (ASTME, 84-01) that measures the flame spread and smoke development of building components in a fire. They are stronger than concrete, steel, stone, wood, or aluminum columns. With the look and feel of natural stone, our columns are popular for interior and exterior use. FRP columns offer exceptionally low maintenance, the look-and-feel of natural stone, and a range of applications unequalled by conventional wood columns. They are non-porous, waterproof, and impervious to termite and carpenter ant attack as well as staining and decaying fungi. High-humidity environments that are so hard on wood columns have no effect on these FRP columns; they are rot-proof because they absorb virtually no moisture. In fact, temperature extremes and thermal cycling have very little effect on FRP columns. Fluted Shaftsare designed to have half round vertical grooves on them.
