18mm plywood is commonly used in construction, furniture making and interior joinery where strength, stability and durability are required. It is manufactured by bonding multiple layers of timber veneers with alternating grain directions, creating a strong and dimensionally stable panel with reduced movement compared to solid wood.
This cross-laminated construction provides consistent thickness, good load-bearing performance and resistance to warping, making 18mm ply boards suitable for shelving, cabinetry, flooring, wall panelling and structural applications. Depending on the grade, it can be easily machined and finished with paint, veneer or laminate.
18mm boards offer strength for subfloors, overlays, walls, roofs and partitions. Rigid, load‑bearing and ideal for light construction.
Preferred for furniture, cabinetry, doors and joinery, offering rigidity, screw‑holding, warp resistance and a smooth, paintable surface.
Engineered plywood is a manufactured wood panel designed to provide consistent and reliable structural performance. It is produced from graded timber veneers bonded together under controlled conditions to achieve uniform strength, stiffness and dimensional stability.
The manufacturing process allows precise control over veneer quality, adhesive bonding and panel construction, resulting in predictable load-bearing behaviour and long-term durability. Depending on the specification, engineered plywood can be manufactured for interior use, moisture-resistant environments or structural applications, making it suitable for projects where material consistency and performance are critical.
Marine grade 18mm plywood, BS1088‑certified, resists moisture for boats, wet rooms and outdoor structures, ensuring durability in damp conditions.
Hardwood or birch 18 mm plywood machines precisely, ideal for CNC parts, jigs, fixtures and detailed panels where accuracy and repeatability matter.
Order plywood cut to size made exactly to your measurements. Our cut-to-size plywood is ideal from building projects to furniture making, cabinetry and joinery.
We use modern panel-saw machinery to cut 18mm plywood sheets cleanly and accurately, delivering consistent results with minimal waste. Whether you need a single panel or multiple plywood boards for a full project, our service removes the need for extra cutting, handling or setup.
For more detailed work, our CNC plywood cutting service is available. It’s perfect for shaped panels, repeated components and precision work. Simply enter your measurements and design, get an instant quote and order plywood cut to size online with confidence.
When selecting birch plywood, the surface veneer grades are one of the most important quality indicators — especially for visible furniture and finish-work. Birch plywood is graded using a two-letter system B/BB or BB/BB.
Birch plywood is manufactured from multiple thin layers of birch veneer, known as plies. These plies are laid with the wood grain alternating direction from layer to layer, a process that gives plywood its strength and stability.
Our plywood sheets are supplied as full panels, suitable for standard joinery and furniture applications, manufactured to a consistent 18mm thickness, with optional precision cut-to-size, CNC machining and panel finishing services.
