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.

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.

In some of the plywood pieces, the glue layer isn't completely even, for example, the glue layer might start off one thickness, and then get thicker, and then go back to the original thickness, meaning that the adjacent wood layers become really thin to accommodate the thicker glue and to maintain a consistent overall plywood thickness. Maybe this is just normal for plywood, i don't know.
