The team at Structural Pergola Systems has over 25 years experience constructing commercial and residential pergolas, custom decks, gazebos and other outdoor living spaces. SPS has been using structural fiberglass on their shade design for over 20 years.
Structural Fiberglass Reinforced Parts (FRP) developed by SPS provide the best material for outdoor structural building applications. Our beams have the warm natural look of milled painted wood without the rot or continuous maintenance of wood. It is does not require maintenance like PVC (vinyl), is substantially stronger than PVC (approximately 6x the stiffness), has considerably less expansion and contraction with temperature, and does not lose its strength at high or low temperatures or become brittle as PVC is prone to do. Our beams are high strength like aluminum but not prone to dents and dings like aluminum and are lighter in weight.
Our beams can out-span PVC at 24' without use of additional columns which sets us apart from the competition.
