Light, versatile, and naturally charming, pine is a classic softwood known for its workability and wide range of uses. We offer high-quality pine lumber, panels, and mouldings perfect for furniture, shelving, trim, panelling, and DIY projects that call for a warm, natural look. Pine features a pale yellow to light brown colour with a straight grain and characteristic knots that add rustic appeal. It’s easy to cut, sand, stain, and paint—making it a favourite among woodworkers, builders, and hobbyists alike. Whether you're crafting something new or restoring the old, pine offers the flexibility and affordability to get the job done right. As a proudly Canadian company, Windsor Plywood specializes in hard-to-find wood products and provides expert, one-on-one service. For everything from home décor to construction, pine delivers dependable performance and classic style that fits virtually any project.
Flat stock, also called S4S (surfaced four sides), is smooth-planed lumber in standard widths used as trim, casing, panelling components, shelf edging, and general finishing work. It has no decorative profile. The clean, flat face is the design and it is particularly popular in craftsman-style and contemporary interiors.
Common species include pine, poplar, oak, maple, and MDF in painted grades. Species selection depends on the application. Poplar and pine take paint well and are cost-effective; oak and maple are used where the wood grain will be visible. MDF flat stock is the smoothest option for painted trim.
Flat stock is available in standard nominal widths from 2 inches up to 12 inches and beyond, in various thicknesses. The actual finished dimensions are slightly under the nominal size after planing. Windsor Plywood can confirm available dimensions and lengths for specific project requirements.
Flat stock is one of the defining materials of craftsman-style trim. Craftsman casing typically uses wide flat stock with a back band detail, and craftsman baseboard uses flat stock with a cap moulding. The result is clean, architectural, and easy to execute compared to heavily profiled traditional trim.
Yes. Wider S4S flat stock in species like maple, oak, or pine is a practical shelving material, particularly for built-in applications and shop shelving. It should be appropriately sized for the span and load. Unsupported spans longer than 24 to 32 inches in 3/4-inch material will sag under significant weight.
