What Does F11 Mean?
The 'F' designation refers to the stress grade of the structural plywood under AS 1720.1 (Timber Structures). F11 indicates a specific minimum bending strength and stiffness rating that qualifies the panel for structural load-bearing use in construction. It is the most commonly specified structural ply grade for general residential and light commercial building applications in Australia. F11 Structural Plywood is manufactured with an exterior-grade adhesive bond (Type A or B bond to AS/NZS 2269), making it suitable for applications where some moisture exposure is expected during construction, though it is not a substitute for Marine Plywood in permanently wet or submerged environments.
Why Specify F11 Structural Plywood?
A certified, versatile structural panel engineered to perform across the full range of residential and light commercial construction applications.
