Whatever the application, we have a range of plywood types to choose from which can be cut to any size or shape using our CNC router for a great level of accuracy and repeatability. All you need to do is send us your drawings in either CAD format or a sketch and we can cut it. As well as cutting shapes and curves into plywood sheets, our CNC router can also be used for rebating, pocketing and hole cutting, for most other sheet materials in addition to plywood. We also provide laser cutting and CNC engraving services for added decorative options. 

If you’re looking for a material for printing, you may want to consider birch plywood. Using state-of-the-art UV printers, we have the capability to print full sheets of plywood in one go, providing a reliable finish and quicker results than can be achieved with painting. We currently only list 8x4 sheets (2440x1220mm) but we can purchase and cut sheets of up to 2000x3000mm, so get in touch with our team today to discuss your requirements. We offer optional next day delivery if you’re working to a deadline and if you have a larger order, we have our own transport service which operates throughout most of the UK. If you have a bigger project and require ongoing supply, contact us to discuss bulk discounts and regular supply orders. 

18mm plywood sheets strikes 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 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.

 

Types of 18mm Plywood and Their Gradings

There are several different varieties of plywood, depending on the application you’re using it for, but the four most common types of plywood are softwood, hardwood, birch and marine ply. Wood comes in a variety of grades; we offer the grades listed below. See our plywood grading guide for more information on the types available.

  •     Softwood plywood is the most commonly manufactured plywood and is available in various thicknesses. It’s typically used in construction projects as it’s affordable and versatile. There are several grades of this wood to choose between, from C+/C grade which has knots on both sides of the wood, with those on the facing C+ side filled and touch sanded.
  •     Hardwood plywood is made from stronger timbers and is commonly used for applications which require longevity. Chinese hardwood plywood is a high BB/CC grade wood which means it has few knots and slight discolouration to the surface of the wood, with a CC grade reverse. 
  •     Birch plywood that we offer comes in high B/BB grade which provides a clear and smooth surface and is best-suited to applications where the appearance of the wood is important or for printing onto.
  •     Marine plywood is for use in environments where the wood is exposed to moisture for extended periods. The type of wood we offer has a high-quality BB/BB face grade and is well-suited to demanding environments such as gardens, bathrooms and parks as well as for roof supports and advertising panels.

 

Advantages of 18mm Plywood Sheets

Plywood has a great selection of brilliant properties that make it a useful material, from its strength and lightweight qualities to its ability to spread the weight of items out efficiently for less stress and tension on the wood. Plywood is resistant to shrinkage, warping and twisting, so any application it is used for is built to stand the test of time. It’s also resistant to changes in moisture levels and temperature, without showing signs of delamination or a loss in structural integrity. 18mm sheets are naturally sturdier and more stable than thinner sheets of plywood, so they’re perfect for projects where this quality is required.

 

Applications of 18mm Plywood Sheets

18mm plywood sheets can be used in a variety of ways, from general joinery to furniture making. The affordability of plywood makes it ideally suited to temporary construction and concrete frameworks. It’s also a great material for shelving, wardrobes, cabinets and doors. 18mm sheets are well-suited to applications that make use of its stability and rigidity, as it won’t warp or bend when exposed to harsh conditions. 

Frequently Asked Questions

Can you paint plywood?

You can paint plywood, but be sure to use primer, as plywood will absorb more paint than you would expect so the primer seals the plywood, and allows it to take to the paint more easily keeping your surface smooth and sealed.

Can you bend plywood?

It is possible to bend plywood. There are numerous ways of bending plywood, but if you are after a sheet that cannot be bent, look at our MDF sheeting.

What is plywood used for?

Plywood can be used for a wide range of versatile structural applications whether interior or exterior, from furniture to internal panelling.

How strong is plywood?

Plywood is relatively strong as it is numerous layers of wood pressed together. For a stronger piece of plywood, look for 5-ply or multi-ply sheets as these will have more layers, and thus more strength.

What are the types of plywood?

We sell a variety of types of plywood, including softwood, hardwood, marine, and birch, all of which have specific characteristics and will aid specific projects. For more information on the respected types, read their descriptions at the bottom of their product pages.

Can I cut plywood?

It is possible to cut plywood yourself, but we are able to do it for you if you request at the point of ordering. To do so yourself please follow safety procedures, and use a sharp saw else you risk the sheet breaking.

How is plywood made?

Plywood is made by glueing a series of thin veneered sheets of wood together. Each adjacent layer is rotated by up to 90 degrees to reduce the risk of splitting when nailed in at the edges. This technique, called 'cross-graining', improves strength, stability and prevents warping, making it an excellent general-purpose construction panel.

How do you seal plywood edges?

Plywood should be sealed to prevent moisture from affecting the sheets and causing warping. The sealant you use will depend based on how you intend to use the plywood, but you should use something quick-drying and can withstand all temperatures, and be compatible with paint if you intend to paint your plywood.

I would recommend Cutmyplastic, they provided exactly what I was looking for. I was building a backscene for my model railway. I wanted material that was flexible, manageable, indestructable and easy to cut. It was all of these and easy to paint, too. No need to cover with paper.
