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 only ordered a small piece of melamine plyboard for a small project. It arrived when expected and and well wrapped. I would recommend Cut My to anyone which I have already done and would use them again if a project requires melamine again.

Two out of 3 marine-plywood boards (so supposedly robust) were okay, but the third began delaminating and required glueing in order to be able to be used. Time was an issue on the job, otherwise I wouldn't have used the delaminating board at all. This was reported to Cut My on the day of delivery. A "ticket" was created and a holding email sent, but there was no further follow-up. Otherwise, the service was useful and relatively efficient, but the product has let the company down, hence this rating.
