Are Fiberglass Porch Columns Hollow?
In fact, all porch columns, no matter if they are round, square tapered or non-tapered fluted or plain are all hollow. Also when you look at the different materials: polymer stone, fiberglass, PVC and even wood they are all hollow. This has to do with the way each of them are made. The fiberglass and polymer stone porch columns all come from a mold that has the shape of the part. The fiberglass mixture is poured into a closed mold, rotated very quickly, and then then the columns dry while they are spinning leaving the column hollow. FRP porch columns are made in halves by spraying with fiberglass strands similar to the manufacturing of a fiberglass boat. The halves are glued together in the factory or on-site creating a whole column once assembled, glued and after Bondo is applied. A wood porch column is made by gluing staves together in a circular form and then turning and cutting them on a lathe. Lastly, PVC porch columns are made from a cut out of a flat sheet of PVC and then assembled in our factory (or on-site) to make the finished square product.
