18mm plywood sheets strike the perfect balance between affordability and great quality, making it a brilliant material for a host of different applications. The method for constructing plywood sheets involves layering sheets of wood at contrasting 90-degree angles and securing them with glue and compression for a strong and hard-wearing material. The result is a product that can withstand weight well and resists shrinkage, warping and twisting. We offer custom-cutting services that enable you to purchase plywood sheets in any size or shape to suit your needs.

Key Features

  • Strength - The cross-laminated layered construction provides impressive strength for the thickness. 18mm plywood can handle heavy static and dynamic loads.
  • Stability - Layers bonded at perpendicular angles resist expansion and contraction to provide sheet stability.
  • Affordability - Less expensive than solid timber, plywood makes an economical structural material.
  • Workability - Plywood machines, cuts, drills, and sands with ease using standard woodworking tools.
  • Weather Resistance - Proper exterior glues and treatments allow plywood to be suitable for outdoor uses.
  • Versatile - From indoor furniture to outdoor construction, plywood has vast uses across industries.
  • Consistency - Factory pressing and gluing ensures consistency not found in solid wood.

With its balanced properties, 18mm plywood can tackle heavy-duty projects while remaining an affordable and workable sheet material.

Uses

With its rugged durability and 18mm thickness, 18mm plywood sheets are ideal for a wide variety of demanding applications:

  • Construction - The sturdy 18mm profile makes plywood suitable for structural applications like concrete formwork, hoardings, temporary flooring, wall sheathing, and small building projects.
  • Flooring - Plywood's dimensional stability is advantageous for subfloors and underlayment, providing a flat and rigid surface for the finished floor.
  • Furniture - From cabinet carcases to shelves, counters, and tabletops, 18mm plywood has the strength to form the core structure of heavy-duty furniture.
  • Packaging - For hardwearing transit and storage crates 18mm plywood can withstand the knocks and loading pressures.
  • Joinery - Plywood's ability to be precision machined makes it perfect for structural joinery tasks indoors and out.
  • Vehicle Outfitting - The ruggedness of plywood is useful for truck, trailer, and van linings, floors, and storage systems.

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.
