I have a project that needs smaller lumber, 1x4s, 1x3s, and 2x2s. This project is rough carpentry just a garage shelf. I have built one example of this shelf already. I did it over a year ago and I did not pay much attention when selecting materials. I have no idea what it cost or what I used! I want to be more careful this time.
When I look at the websites of the big-box stores to estimate my costs I see three types listed for this lumber and the approximate cost for an 8' length:
- firring strips, $2
- select grade, $10
- pressure treated, $4
Why is there such a variation in price?
How can I tell which grade to get?
I assume that the select grade is straighter or has fewer defects. I expect the firring grade to be very rough and probably warped. Would the pressure treated be a compromise between cost and straightness?
