What is F17 Formply

What is F17 Formply?

F17 Formply is a high-grade structural plywood specifically designed for use in formwork applications, where concrete is poured to create structures like walls, columns, slabs, and beams. It is engineered for durability, strength, and moisture resistance, making it ideal for repeated use in construction projects. The "F17" designation refers to its stress grade under Australian standards, indicating its mechanical properties and load-bearing capacity.

Compliance with AS 6669

F17 Formply complies with AS 6669 (Australian Standard for Plywood – Formwork), which specifies requirements for formwork plywood, including:

• Strength and stiffness: Ability to withstand concrete pressure and structural loads.

• Moisture resistance: Treatment to resist delamination and swelling when exposed to wet concrete.

• Surface finish: Smooth face coatings to ensure clean concrete finishes.

• Dimensional stability: Minimal warping or distortion during use.
  Certified F17 Formply will bear markings confirming compliance with AS 6669.

Primary Applications

• Concrete formwork: Reusable molds for pouring foundations, walls, beams, and slabs.

• Structural temporary works: Support structures during construction.

• Architectural finishes: Smooth concrete surfaces requiring minimal post-pour treatment.

Precautions for Use

• Inspect before use: Check for delamination, warping, or surface damage.

• Avoid overloading: Follow load limits based on span and concrete pressure calculations.

• Edge sealing: Seal cut edges with waterproof sealant to prevent moisture ingress.

• Release agents: Apply recommended formwork release agents to ease stripping and preserve the plywood.

• Safety handling: Use proper lifting equipment to avoid physical strain or plywood damage.

Storage Guidelines

• Dry, flat environment: Store in a covered area to prevent water absorption or UV degradation.

• Stack horizontally: Place on a flat, level surface with supports to avoid sagging.

• Avoid ground contact: Use pallets or spacers to elevate stacks and ensure airflow.

• Protect from weather: Cover with tarpaulins if stored outdoors temporarily.

• Rotate stock: Use older batches first to prevent long-term storage damage.

F17 Formply is a cost-effective, reusable solution for high-quality concrete forming, provided it is used, maintained, and stored in accordance with industry standards and manufacturer guidelines.
