Trex is the #1 decking brand in the world and the country's largest manufacturer of wood-alternative decking and railing products. Low-maintenance Trex won't splinter, rot, warp or need sanding and staining like wood.

Let Brock's help you take the guesswork out of designing your deck. Our experienced staff are here to help you select which style works best for your outdoor space. Choose from many colors that mix and match beautifully with coordinating railing.
