Analyze Results and Recommend Framing Spacing

What happens here

The presenter holds up the broken pieces of composite decking to visually demonstrate the results. He reiterates that the 16-inch on-center spacing failed at less than 1 ton of pressure, while the 12-inch on-center spacing withstood 2 tons of pressure before breaking. He concludes that 12-inch on-center framing provides twice the strength and is often a recommended or required practice for structures like stairways (sometimes even 8-inch on-center). He advises that the minimal extra cost for 12-inch on-center framing for a deck is well worth the significant increase in strength and durability.

Goal: Interpret the test results and provide practical recommendations for composite decking installation.
