Our Products
Pressure
treated
Pressure-treated wood is the most popular decking material in the United States, offering an affordable solution for your project. Typically made from Southern Yellow Pine, it’s treated with chemicals to help protect against rot, fungi, and wood-boring insects.
Cedar
Cedar decking is valued for its warm color and natural beauty. It offers excellent dimensional stability, resisting cupping and warping. Naturally rich in tannins and oils, cedar is inherently resistant to rot, decay, and insect damage. Left unfinished, it gracefully weathers to a soft silvery gray over time.
Hardwood
Hardwood decking is crafted from dense, exotic woods known for their striking grain, strength, and lasting durability. Naturally resistant to rot and insects, it offers both beauty and performance. When left unstained, hardwood decking will age to a soft, silvery patina.
Composite & PVC
Composite and PVC decking are low-maintenance options that never require sanding or refinishing. Composite decking is made from a blend of wood fibers, plastic, and binding agents, creating a dense, durable material that’s stronger and heavier than natural wood—a true wood-plastic composite.
