3mm Plywood
3mm plywood is a thin, light and easy to handle sheet used for tidy interior work, craft projects and curved designs. A 3mm plywood sheet gives you a smooth surface, a flexible feel and a board that is simple to cut or shape. It is a practical choice when you want clean results without extra weight. Our 3mm plywood 8 x 4 option fits most workshop and site setups.
What is 3mm ply sheet?
A 3mm ply sheet is an ultra thin engineered wood panel made from glued timber veneers. The layers create a stable 3mm sheet wood board that bends gently and stays steady once fixed. This makes 3mm ply a good pick for lightweight furniture details, interior panels, hobby builds and any job where a slim, flexible sheet works best.
What is 3mm plywood sheet used for?
You will see 3mm plywood used for lightweight cabinet backs and simple drawer bottoms where a thick board is not needed. It also works well for decorative wall panels and soft interior features like shaped archways.
For builders, 3mm wood sheet is a favourite material for templates, CNC prototypes and laser cut designs. Designers use 3mm plywood 8 x 4 boards for architectural models, backing boards for mirrors and frames, and tidy lining in vans where weight matters. On the practical side, a thin 3mm plywood sheet is great for small ceiling trims, packaging protection and quick event displays.
Types of 3mm ply
3mm flexible plywood cross grain
This type of 3mm plywood sheet bends across the width of the board. The cross grain structure makes it ideal for tight curves, rounded wall panels, arches and compact furniture details. It is light, easy to handle and gives a smooth surface that is ready for finishing. A practical choice when your design needs a clean bend across the sheet.
3mm flexible plywood long grain
Long grain 3mm ply bends along the length of the board, which helps when you need longer, softer curves or taller vertical shapes. Designers use long grain sheets for columns, curved partitions, van interiors and feature walls where the bend should follow the full height of the panel. It stays stable once fixed and gives the same neat finish as other flexible 3mm ply sheets.
The 3mm plywood sheets come in the standard 2440 x 1220 (8’ x 4’) size and meet the BS EN636 Class 1 rating for dry interior use. Each board has square edging, a smooth sanded veneer finish and an E1 formaldehyde level. The flexible C/C grade allows the sheet to bend cleanly while still giving a tidy face for interior or non structural exterior work. These features make 3mm flexible ply easy to shape, easy to fix and reliable for everyday curved designs and light decorative jobs.
