that's not the test. leave it in the sun for a year. this the test

Mr Bungle :
yeah 12 oc would minimize deflection... but this isn't an accurate representation of deflection whatsoever.

12 is whats required on composit.

12 on center if you are spending the extra on composite decking what a few each boards to stiffen up the decking.

Try that with 5/4 treated lumber...

every seen composite bend in the sun went temperature hits 95+. never go 16 on center with plastic wood

16 min, 12 better

Who uses 3-1/2” net 12” o/c though?

That board wasn’t secured try it screw down

Now screw it down and do it again

we normally screw it down... would still flex not as much though

Maybe 2 ft on center and pre cracked get a load of this guy, some of the cleanest overalls I’ve ever seen. Lol🤣🤣

The ends were not screwed. That’s going to allow more deflection.

You absolutely have to use 12 O .C. on composite decks. They're horrible TBH! It adds a lot framing materials which translates to a lot more $$$ even before the extra cost of the boards. And it gets hot AF in the summer heat.

🤔
For composite decking, we only do 12" span (which can be less than 12" OC depending on the pattern...). Beyond just the stiffness issues, most will begin telegraphing at 16s once the summer sun has gotten to them a few times.

you should fasten it to the blocks like you would on a deck and check deflection again
