12mm softwood plywood provides excellent stability and strength, as its thickness delivers rigidity for larger panels. Softwood plywood is typically used for construction and pre-fabricated components, but it’s also great for furniture that requires strength such as chairs or tables.

Order your plywood sheets cut to size today, with additional options for drilled fixing holes, cutouts and rounded corners.

Details

Softwood ply, often called shuttering ply, is a rough sheet suitable for formwork, shuttering, and basic carpentry like garage shelves for paint or tools. Expect knots, dents, filler, and warping on the surface. It's not for fine joinery like bookcases that require a smooth finish - we'd recommend birch ply for that.

Typically made from spruce, pine or cedar, 18mm softwood plywood offers versatility and value for construction and home projects. It provides excellent stability and rigidity in large sheets, ideal for walls, floors, roofing, and general joinery.

We stock lighter-toned Brazilian softwood with straighter grain and uniform texture. Benefits of our 18mm ply sheets include strength, workability with standard tools, compression resistance without bending or warping, and durability. Other sizes like 12mm softwood ply are available too.

Applications taking advantage of the rigidity and affordability include construction, concrete work, and any project needing large, stable sheets. Choose high grades to showcase the wood's natural beauty, or lower grades for hidden structures. We also supply marine, hardwood, and birch plywood.

I bought 2 birch plywood panels (12mm) for use as kitchen cupboard shelves and they are perfect for the job. Good quality with a nice finish and are now loaded with cans, etc.

Ordered plywood cut to size in order to build a custom display for housing miniature bronze animal skulls. The wood was well finished without rough edges and were cut accurately. I aged the plywood with a wire-wool/vinegar solution before assembling then finished with linseed oil.

I built a cabinet to hide my tv. I have no carpentry skills but cut my cut the pieces exactly as ordered and it looks great (I had a little help putting it together!). I couldn’t have done it without cut my’s help. Excellent service at reasonable price.
