It’s not metric as fastsuv points out , the pressure treated boards are 1 1/4 inch thick or 5/4 , I didn’t name it , the deck industry did.
21- 16 foot 5/4 @ $16.00 each equals $336.00
21 X 16 feet = 336 linear feet X $4.00 = $1,344.00
a $1,008.00 difference, then you have to figure in the fasteners and clips and my deck was built for 5/4 boards , so 16” in centre for the joists, the composite requires 12” on centre .
My lumber for the deck surface , new posts for the privacy fence and railings with screws and the Camo tool came to $1,175.00. And I factored in , I’m 66 and most likely will not be in this house in 20 years. So, I went with the less expensive wood.

I gotta give my deck some love this season as well. It's 20 yrs old & showing it's age, in spite of my staining it a few times. I have always hated that nails were used.
I plan to use deck screws. & the CAMO tool looks cool. Although I think I can still "toe-nail" the screws w/out that tool. Time will tell. Would love to use Trex or similiar, but likely end up using Yellow wood®
For deck surface & rail tops.
I considered that , but regular deck screws the heads are to big , allowing water to seep in and rot the wood, then I thought about using the Camo screws and predrilling, each and every hole. I also considered 2 1/2 inch hot dipped galvanized finishing nails , to tedious to nail set each one and the possibility of leaving hammer marks in the wood.
I like the yellow wood , but we don’t have that option up here.

Blue- Good point about big heads on deck screws.
So do you have PT wood up there ? They did away with it around here in the South.
A while ago (maybe 15 yrs ago?), they changed the formula for PT wood from CCA (chromated copper arsenate) to remove the chromate and arsenic in it. It was the arsenic that killed mold and insects.
The new formula is ACQ (alkaline copper quaternary) and uses copper and ammonium compounds to kill mold and insects (boat bottom paint contains copper to keep marine organisms from sticking to the hull) as copper is toxic to living things.
Unfortunately the new formula is highly corrosive. You have to use stainless or coated fasteners or else it will eat through the fastener in a short time. Look for fasteners that are rated approved for ACQ.
Yes, it’s called brown wood, I built our fence with it , in 2015, still looks great no fading
Blue- Never heard of brown wood. But sounds good.

Steve- Thanks for the 411... I remember all the chaos to have PT wood removed from playgrounds & etc. That was good wood, for longevity. Maybe not healthy for us tho. Was this for the entire US ?
That new stuff (ACQ) is not related to Yellow Wood® then, is it ? Billy
Today the HD emailed to notify me my order was ready, while on the way home , I stopped at local grocery store and picked up a few things, while waiting in line to go into the store I noticed how level the BlackSwan looked on the level paved parking lot
then we took the usual drive in a Sunday with Sweetie’s mom, and the odometer turned to this!
