| 9mm structural plywood | Light structural applications, wall lining and supported construction work where the specification suits. |
| 12mm structural plywood | General construction, wall lining, sheds, outbuildings and supported structural applications. |
| 15mm structural plywood | Construction work needing a stiffer sheet, including roof decks and wall lining where suitable. |
| 18mm structural plywood | Flooring, subfloors, roof decks, storage areas and projects needing extra stiffness. |
| 25mm structural plywood | Heavy-duty construction, platforms and thicker structural build-ups. |
Structural hardwood plywood from 9mm to 25mm
The 9mm, 12mm, 15mm, 18mm and 25mm options are the structural choices within this range. They are used for building and construction work where the board specification, thickness, span, support spacing and fixing pattern suit the project.
This plywood is classified to EN 314-2 Bonding Class 2 and EN 636. Class 2 is designed for high-humidity conditions. Where a drawing, architect or project specifies a different bond or use class, match the plywood to that stated requirement.
What does WBP plywood mean?
WBP plywood is still common buying language for plywood associated with weather-resistant glue bonds. Modern project selection is better based on the board's declared EN classifications, so we show the current EN 314-2 Class 2 and EN 636 information alongside the familiar WBP wording.

Structural or general-purpose hardwood plywood?
Choose this range when you need the broader 3.6mm to 25mm thickness choice and structural options from 9mm upwards. For dry interior cabinets, shelving, furniture and joinery in 12mm or 18mm, compare our General Purpose Hardwood Plywood Sheets.
