Southern yellow pine?

where is southern yellow pine grown? Can a guy buy ruff sawed lumber somewhere like you can get ruff oak up here in the north? I need to build some trusses and most big buildings here where the snow load is 60 lbs. use southern yellow.
 
Southern Yellow Pine is more or less a descriptive name for several species of pine that are heavily grown in the south, long leaf, slash pine, short leaf and loblolly. Georgia Pacific is a big supplier of Southern Yellow Pine and Home Depot, Lowes and I am sure many more carry their lumber. I would think it is sold over most of the country.
 
Not sure where you're located, but here in Central NY, Larch is a good tough wood, and can be bought rough from the mill.
Hemlock is also available, but I don't think I would use it for anything structural

Hemlock is actually a very good structural wood. Not good at being pretty, very good at being strong. If it's dry, predrill the holes for any fasteners, though. You can nail it green. Look out for the splinters.

The thing with trusses and rough lumber is that YOU are doing the strength grading for the lumber going into the truss. Fine if you know what you are doing. Not so fine if you are taking a truss designed intended for individually tested graded lumber and replicating it in rough. Overbuild a little, and know where not to put a knot.

Oak is by most measures stronger than SYP - it's just not "construction lumber" in the same way, so you don't see it commercially all that much.
 
Grown all over the "South" I am knee deep in it here in North East Texas. you can buy it rough and green or kiln dried framing lumber. And yes lots of trusses are built from it. I don't know your location so you may not have it available in rough cut. We have quite a few local sawmills that will cut whatever you want. JB Dyer
 
Old power poles. Every year the power company replaces poles. Most of the old ones are yellow pine. We have them sawed up to make hay wagons. They work well because they are tight grain. I'm in Michigan
 
The Southern Pine Inspection Bureau--SPIB--will inspect and grade lumber at the sawmill---there are many grades of southern yellow pine and all have different allowable stresses.
 
SPIB #2 is usually used for home construction. #3 has more uneven places caused by variations in the shape of the tree, rounded on one edge of a 2x4 example, but otherwise could be stronger than #2.

E. Texas "Piney Woods" has many saw mills and you can go to the mill and get a good deal on great lumber.
