One of the top benefits of 18mm hardwood plywood is its excellent strength-to-weight ratio. At 18mm thick, these plywood panels are thick enough to provide robust structural performance, yet still lightweight and easy to handle compared to solid wood alternatives. The cross-laminated layered construction gives the wood impressive strength and rigidity that allows it to handle both static and dynamic loads without excessive deflection.
The layered plywood composition also provides exceptional resistance to expansion, contraction, warping, and twisting. This dimensional stability allows 18mm hardwood plywood sheets to hold up well in varied temperature and moisture conditions over time. This stability and resilience suit plywood nicely to structural framing and flooring applications where a flat, level surface is critical.
When it comes to workability, 18mm plywood sheets offer advantages as well. Their smooth, splinter-resistant faces machine cleanly and sand to a consistent surface. The plywood takes stain, paint, lacquer and other finishes excellently. And compared to solid wood, the layered construction minimises natural defects. The panels can be easily cut, drilled, and machined using common woodworking tools.
With this winning balance of strength, stability, durability, and workability, it's easy to see why 18mm hardwood plywood is commonly used for:
Material | Plywood |
Finish | Hardwood |
Thickness | 18mm |
Maximum Sheet Size | 2420mm x 1220mm |
Minimum Sheet Size | 100mm x 50mm |
Plywood Grade | BB/CC |
Manufacturers Tolerances | +/- 10 % plus 0.4mm (e.g. 5mm cast sheet could vary from 4.1mm to 5.9mm) |
Cutting Tolerances | +/- 1mm |
Opt for thin 4mm or 6mm plywood for arts, crafts, and hobby builds. Use 9mm to 12mm ply for furniture and cabinetry. 18mm plywood is suitable for flooring, construction, and other heavy-duty applications.
Our hardwood plywood comes unfinished but we can apply a protective lacquer coating upon request. You can also choose to finish the wood yourself with stains, paints, or clear coats.
Store plywood flat on a level, dry surface indoors. Avoid moisture and rotate stock to distribute acclimation evenly. Keeping the sheets supported prevents warping over time.
For clean cuts, use a sharp fine-tooth blade on a table saw or circular saw. Cut with the good face up, take it slow, and make multiple passes when needed.
Finish raw plywood edges with banding, edging, trim, or staining/painting for a clean look. We recommend sealing outdoor plywood edges with epoxy to prevent moisture damage.
Apply a fast-drying water-resistant sealant compatible with your project finish. Epoxy and urethane formulas work well, and sealing edges prevents moisture damage over time.
