Square Load-Bearing
Craftsman
Columns
Our square load-bearing craftsman columns are made from fiberglass-reinforced polymer (FRP). Pound for pound, they're stronger than concrete, steel or aluminum. These columns are virtually maintenance-free. They're impervious to terminte and carpenter ants as well as fungi. If you don't need load-bearing columns or want a column that wraps around an existing support, you can save money by using our square PVC columns.
