Details

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:

  • Structural flooring and subflooring
  • Wall, ceiling, and roof sheathing and panelling
  • Concrete forming applications
  • Heavy-duty shelving and storage
  • Cabinetry, doors, and millwork
  • Furniture and shop jigs
  • Packaging and shipping crates
  • Workbenches and tables

Frequently Asked Questions

What thickness should I choose for my project?

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.

Do you offer pre-finished hardwood plywood?

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.

What's the best storage method for plywood sheets?

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.

What tools should I use to cut plywood?

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.

How can I finish the exposed edges of plywood?

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.

How should I seal the edges of plywood?

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.

Delivery depends on the size of your order

I was going to buy a sheet, cut it (probably involving buying a jigsaw to cut it) but I got this instead, for way less money and hassle, and delivered in about five days! Millimetre perfect, too. Couldn’t be happier

Delivery of the cut to size items was as stated, I was concerned it would be delayed as I had a particular time line due to time constraints, the goods came perfectly within my schedule. The items were very well packed to avoid damage. I can easily recommend Cut My and would use them again without hesitation.
