Any body seen nails used to secure trailer boards?

reading the original post...

are you saying that the new boards are stamped saying that they are treated even though they don't appear to be? just wondering because i've seen a lot of variations in recent pressure treated lumber - some looking pure white and some deep green. either way, new pressure treated certainly doesn't last as long as the 20 year old stuff, but i guess that was so kids could chew on it longer without major issues.

Sorry im not the best person at writing.

The new boards ARE NOT treated (not yelling just wanted to make it clear). The only thing they are stamped was like SPIB (southern pine Inspection Board, or something) NO2 prime, and KD (kild dried)19.

I am a forester by schooling and heve a minor in Wood produckts.This was the time of the swap over in consumer lumber from CCA. My professor in wood products classes at the time told us they had done studies that said you kid would have to eat about 1.5lbs of treated CCA boards to get killed.

He was an american but of Korean decent. He was born here but you could swear he came here at like 20 yrs old his accent is so thick. Any way in his accent he would say "Your kid would have to eat something like 1.5lbs of wood to get sick, what are they doing eating wood anyway, and what kind of parent dosent notice their 3 year old eating that much 2x4."!

Popular is used on flatbeds for heavy equipment, once dried it is all but impossible to drive a nail through though. No need to treat it but with the stamp you described I'd say it is unlikely popular is what was used.

Mike,

I expect that most of us in the Southeast associate poplar with yellow poplar/ tulip poplar -- definitely not the poplar that you are referring to.

Thanks for clearing that up! As a forester i should know what he is talking about but have no clue. Yellow poplar (Lireodendron tulipefera) is trash for anything other than interior painted trim. Wood is so soft and it rots on a still living tree at a wound site. Once dead i think it begins to rot after the first rain and sun exposure. It mildews after the first rain i think!

This stuff is weak too i think anything would crack Y. poplar boards on a trailer unless you had cross members every 18"!

Ramsets/hilti etc, used to fix wood purlins to steel building framing. They get used a lot in construction going into mild steel. I've seen them shot into 3/8" steel. You aren't going to pull them out. When the boards rot out you grind them off.

Was going to say your going to have to grind/torch them out anyway regardless of what they use.

I mentioned back in June on another thread that my new small Carry-On brand trailer had the boards nailed to the steel cross members. I don't much like it as I figure they will be a real PITA to get out when the boards need replacing someday.

BTW I buy a fair amount of treated lumber and it almost never has a marking on the board itself to indicate it is treated. They do have a little plastic tag stapled in one end of the board stating they are treated and what use they are rated for as in ground contact or not.

Yea i forgot about the tag on the end. But i do know they have to be labled somewhere. The mill stamps it and that can be a total different place from the treatment facility although most cases it is the same. At at the time wood is running it can either be treated or non. After treatment they dont dry them so i would doubt they re run the boards and stamp them soaking wet. I will look closer, although i doubt these are treated they look like they havent sat out long, like in the weather, and they are fairly dry like wood you buy thats untreated.

Its been 25 years, but the mill I worked at kiln dried their treated wood. And then stapled a plastic tag to the end, no stamp.

Its not dried to the same MC then, the stuff sprays water out when you nail it where other boards dont that are untreated.
