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 needed to replace the tongue & groove on the doors to my summerhouse but was reluctant to fit anymore as it is south facing and the chances are the t & g would expand and start to pull away from the frame again. I chose this marine plywood so I could use my circular saw to create grooves to make it look like t & g. In general it has come out quite well, the first one was best but the other two are ok. Just need to stain & fit.

Good surface finish, resistant to water immersion. Too soon to know how durable it will be.

This was cut for me to make a replacement shed floor. Its perfect - fitted like a glove and is sturdy. What more do I need really! Would use MyCut again if I needed a custom cut piece of wood.
