Plywood Sheets

Made of thin layers of wood glued together under heat and pressure, plywood sheets are durable, yet lightweight. The direction of the wood grain alternates with each layer—known as opposing grain—making these sheets strong enough for building ramps and shelves or repairing holes in floors and ceilings. Opposing grains also limit movement, keeping each layer from expanding or contracting too much—otherwise moisture could warp and split these sheets apart. All are made of real wood, so you can drill, saw, sand, paint, and stain them.

CDX Plywood—CDX-grade plywood sheets are best for applications that will be painted or covered by another material. They can be briefly exposed to moisture, such as during construction, but shouldn't be exposed long term. One side is C-grade, so it may have minor surface defects and knots. The other side is D-grade, which may have more defects and bigger knots.

Marine Plywood—Marine-grade plywood sheets meet BS 1088, an international standard for plywood made from water- and fungus-resistant hardwood. Often used to make boats, their layers are bonded with waterproof glue, so they won’t bubble, buckle, or delaminate with long-term exposure to weather and water. Boiling temperatures and steam aren’t a problem either. Compared to CDX plywood sheets with the same thickness, these sheets have thinner layers and more of them, making this plywood stronger and denser. Each layer is made from one piece of wood, so there are no gaps in the middle layers that could weaken the sheet or leave a rough edge when you cut or sand it. The outer layers have a finished appearance that doesn’t need to be painted.

3/4" Thick—For load-bearing applications, use ¾"-thick sheets.

Balsa Wood Cores

Lighter in weight than any other wood, yet still strong, these balsa cores stiffen composite sandwiches without weighing them down. They resist damage from impact and repeated use. Because they don’t let heat or sound pass through quickly, these cores are good natural insulators. They also resist chemicals. All come from balsa trees grown in FSC (Forest Stewardship Council) certified forests.

Rigid

Rigid cores are often used in panels for partitions, industrial tanks, and other stiff structures.

Medium Density Fiberboard Sheets

Also known as MDF, these fiberboard sheets are smoother, denser, and more uniform than real wood, so they are often used as spoilboard and shelves. They meet the indoor formaldehyde emission requirements of ANSI A208.2 and the California Air Resources Board (CARB).

Basswood Strips

Also known as linden, this basswood is moldable and lightweight, making it ideal for shipping boxes, crates, handles, and building models. It is one of the softest hardwoods and is easy to machine. Basswood won’t warp when exposed to humidity and temperature changes. While slightly heavier than balsa wood, these strips bend and curve more easily and are more durable.

Wood Boards

Don’t knock the classics—these wood boards are a strong and affordable building material. Made of spruce, pine, or fir, they’re less dense and easier to drill and saw than hardwood, but still sturdy enough to make into crates and other load-bearing structures. Any knots are tight and spaced apart.

No. 1 Premium Softwood—No. 1 premium boards are the best grade available. They have minimal defects, so they’re good for applications where the appearance of the wood is important.

Whiteboard Panels

Create a whiteboard surface anywhere. These panels are often cut to make whiteboard walls or built into cabinets and enclosures where standard frames won’t fit. The edges are unfinished.

Painted Steel—The choice for busy warehouses. They’re more durable than melamine panels and hold up to a decade of writing and erasing. Cut them with any common circular saw for a clean edge.

Porcelain—Tougher than painted steel, these panels stand up to bumps, nicks, and scratches. They won’t show staining over time, even if marked accidentally with permanent marker, so they’ll last a lifetime. When cutting these panels, you may see hairline chips along the edge, so you’ll need to cover it for a clean look. To minimize chipping, use a circular saw with a low RPM.
