18mm Softwood Spruce Plywood Sheets

Softwood ply is often known as shuttering ply, it's a rough grade of sheet that is suitable for formwork, shuttering and rough carpentry work for example shelves in a garage or a shed to store paint or tools on. You can expect to see knots, dents and filler on the surface, the sheets are quite likely to be warped/wavy. It is not suitable for use in finished joinery like making book cases, desks or any item where the finish is needed to be smooth and presentable, for this we recommend birch ply.

We offer a variety of types of plywood for any application which can be cut to any size or shape using our CNC router for precision and easy duplication. We can cut any shape you need – just send us your drawings, in either CAD or sketch format, and we’ll create it to your exact specifications. As well as cutting any shape or curve, our CNC router can be used for rebating, pocketing and hole cutting on plywood sheets, in addition to most other sheet materials.

If you are looking to print onto plywood sheets, birch plywood is an excellent choice as it provides a great surface for a consistent and professional finish. Using state-of-the-art UV printers, we can print full sheets of plywood in one go, providing a consistent and professional finish at a much faster rate than painting.
