Southern Yellow Pine is known for its strength and density, making it ideal for structural applications like framing. It is primarily grown in the southern United States and is available in the following sizes and grades:

Sizes:

• 2x4 – 2x12, lengths from 8’ to 20’

Grades:

• MSR 2400 – The highest grade of Southern Yellow Pine, machine-stress rated (MSR) for a bending strength of 2,400 PSI, ensuring maximum strength and stiffness. Available with paper wrapping.
• #1 – Minimal knots and defects, suitable for exposed applications.
• #2 – Larger knots than #1 but still suitable for general construction.
• #3 & #4 – Significant knots and wane, primarily used for rough construction or hidden framing where appearance is not a concern.

Pieces per Unit:

• 2x4 = 208
• 2x6 = 128
• 2x8 = 96
• 2x10 = 80
• 2x12 = 64

SPF is valued for its superior strength-to-weight ratio, making it the preferred choice for framing studs. It is primarily sourced from Western and Eastern Canada and the northern United States.

Sizes:

• 2x4 – 2x12, lengths from 8’ to 20’

Grades:

• MSR 1650 – The highest SPF grade, machine-stress rated (MSR) with a bending strength of 1,650 PSI.
• Premium – Minimal knots and defects, suitable for exposed applications.
• #2 Premium – The most commonly used grade in construction.
• #2 – General construction grade.
• #3 & #4 – Utility grades with significant knots and wane, used for rough construction or hidden framing.

All SPF units are generally paper-wrapped.

Pieces per Unit:

• 2x4 = 208
• 2x6 = 128
• 2x8 = 96
• 2x10 = 80
• 2x12 = 64

Euro Spruce shares similar characteristics with SPF but is sourced from European forests and imported through eastern ports.

Precut Studs

Precut studs are made from SPF species and are precisely cut for standard wall heights, reducing on-site labor and material waste.

Available Sizes:

• 2x4 and 2x6
• 8’ wall studs – 92 5/8”
• 9’ wall studs – 104 5/8”

Grades:

• Premium
• Stud

Most precut stud units are paper-wrapped.
