Lumber people, grade question

[Bill M]

I have some 2 x 6 x 18' in my shop with this stamp. I know they came from Leesville Lumber, but numerous people have asked me if they are treated because they are stamped with No. 1. Maybe I'll call them if no one knows.

I believe the HT part means “Heat Treated”. As for actually being sealed, no clue but I’m not seeing anything that suggests it is.

Kiln-dried to 19% and heat treated
no 1 is the grading. Nothing there refer to pressure treated

[BrandonH]

Number 1 grade, kiln dried & heat treated...not pressure treated.

[Bayouboy]

Yep.

[jaspermac]

Leesville lumber doesn’t have a treating facility

[Bill M]

Thanks, guys. I didn't think it was pressure-treated and wondered if I was missing something since I was asked several times.
