Will composite decking break? #deck #carpentry #homeimprovement
What happens here
The wood blocks are then adjusted to be 16 inches apart (16 inches on center), a common joist spacing for decks. The tester again stands on the center of the board, and the deflection is measured. The video indicates a deflection of 3/8 inch, which is significantly more than the 1/8 inch observed at 12 inches on center.
Goal: Measure the deflection of the deck board with joists spaced 16 inches apart.
Tools and materials
- Composite Deck Board — The material undergoing the deflection test
- Milwaukee Speed Square Milwaukee — Measuring the deflection
- Wood Blocks — Providing support for the deck board at 16-inch spacing
