Question Spruce studs...really???

Here in Jersey we always have Doug Fir as the standard lumber material. I went to the orange box for some 2x4 KD studs and they had the usual stack of Doug Fir and a stack of Spruce studs. I have never seen that in this area before. They say No.2 KD HT. What is the HT about? Are they as structurally sound as Doug Fir (for load bearing walls) or are they like white wood? They sure are pretty and straight!

Thanks guys!

Common in Atlantic Canada

I was used to Douglas Fir where I grew up in British Columbia. I've live in Nova Scotia for the last 12 years and spruce is all they use for framing up here.

Here in the South, we have two choices, usually. You can purchase yellow pine, which is really difficult to work with, or (to cover all the bases) a product called SPF. Which can be a mix of Spruce, White Pine or Fir. Mostly it is Spruce.

Douglas Fir is stronger than spruce. It has a greater shear and compression strength. However, spruce is common in stick framing.

Does that mean the spruce acceptable for load bearing walls? Is that a local inspector's judgement?

In the south most framing is done with spruce although headers of any size are yellow pine [also floor joists]. It would be best to check with a local inspector to make sure as specs often change in different regions.

Spruce is fine for stud walls, plates. I would be concerned about using it for joists, rafters, headers etc. where it can have a significant impact on load calculations.
