Engineered wood is designed for strength, stability, and efficiency. Our selection includes laminated veneer lumber (LVL), I-joists, and glulam beams—ideal for load-bearing applications like floor and roof systems.

Hardwood Lumber
For furniture, cabinetry, and custom woodwork, our hardwood lumber selection includes premium species like oak, maple, and cherry. Perfect for interior finishes, crafts, and high-end building applications.

Hardwood Plywood
Get the beauty of hardwood with the convenience of plywood. Our hardwood plywood sheets are excellent for cabinet boxes, doors, and panels—offering superior strength and a smooth finish for staining or painting.

Laminate Products
For countertops, wall panels, and cabinetry, our laminate sheets provide durability and design flexibility. Available in a variety of patterns and finishes to match modern and traditional interiors.

MDF & MDO Panels
Smooth and stable, MDF (Medium Density Fiberboard) is perfect for paint-grade interior trim, shelving, and furniture. MDO (Medium Density Overlay) panels feature a weather-resistant surface ideal for signage and exterior applications.

Plastic Panels
Durable, lightweight, and water-resistant, plastic panels are a great solution for bathrooms, utility rooms, and commercial spaces. Easy to install and clean, they work well in high-moisture areas.

We carry a full range of plywood sheathing options for walls, roofs, and floors, including tongue-and-groove subfloor panels for strength and stability. Suitable for residential and light commercial framing.

Sanded Plywood
Ideal for furniture, cabinetry, and finished surfaces, our sanded plywood offers a smooth surface for paint or stain. Available in multiple species and thicknesses to match your build.

Treated Lumber
Pressure-treated lumber resists rot, decay, and insect damage, making it ideal for decks, fences, outdoor framing, and ground-contact applications. We carry a variety of sizes and profiles for outdoor projects.

Utility Grade Lumber
Great for rough framing, bracing, and temporary structures, utility grade lumber offers value and function when appearance is not a priority. Stock up for jobsite efficiency or DIY use.
