3" x 3" Mill Run SPF Green Rough Dimensional Lumber
This is a 3x3 in mill run SPF (spruce-pine-fir), sold green and rough sawn. It comes in an 8 ft length for stakes, bracing, forming and general-purpose work.
Mill run means it is not sorted to a specific grade, and green rough means it is not dried or planed. Expect a mix of quality with knots and other defects, and do not use it as a structural post or beam. It also still holds moisture, so it shrinks and can check or twist as it dries, and the finished size varies from piece to piece. Check the size against your layout and hardware before you order.
Features and Common Uses
- Mill run SPF, a low-cost option where a specific grade is not required
- SPF is a species group of spruce, pine and fir, light in weight and easy to cut and nail
- Green, with a moisture content above 19%, so it is soft to cut and drill
- Rough sawn, keeping the texture left by the sawmill
- Not pressure treated, so keep it dry and out of ground contact
- A 3 in. nominal square section in an 8 ft length
Commonly used for:
- Stakes, cribbing and blocking
- Concrete forming, shoring and bracing
- Garden and landscape projects above ground
- Pallet, crate and equipment framing

Rough-sawn timber is not milled to a fixed finished size, so actual thickness and width vary by piece and by sawmill. Mill run stock is not sorted to a grade and is not rated for structural use, so confirm suitability with your engineer or building inspector. Green lumber changes size as it dries.
Frequently Asked Questions
What does mill run mean?
Mill run means the lumber is taken as it comes from the mill and is not sorted into a specific grade. It can include a mix of quality, with more knots and defects than graded stock, so it suits jobs where price matters more than strength or appearance.
What is the actual size of a rough 3x3?
It varies. A rough-sawn 3x3 is not planed to a set finished size, so the actual thickness and width differ from piece to piece. A planed 3x3 measures 3-1/2 in. square when dry. Contact us if a specific dimension matters for your project.
What is SPF?
SPF is a commercial species group of spruce, pine and fir. The wood is light and easy to work, and it is graded and sold together as one group.
What does green rough mean?
Green means the timber has not been kiln dried and holds moisture above 19%. Rough means it is sawn but not planed, so the surface keeps its sawmill texture. Expect shrinkage as it dries.
Can I use it for structural posts?
No. Mill run stock is not graded or rated for structural use. Use a graded #2 and better post for decks, porches and carports, and confirm the requirement with your building inspector.
