Trex Signature rod railing brings a minimalist industrial design to residential settings, drawing on the company’s acquisition of commercial architectural railing manufacturer SC Railing. Available in 36-inch and 42-inch heights and in 6-foot and 8-foot lengths, the aluminum railing sections come in three powder-coated color combinations: black/ platinum, bronze/platinum, and black/black. Trex says the railing can be customized with different top rails and is compatible with Trex outdoor lighting components. The rod railing costs about $90 per linear foot.
