Green Kiln Dried Pressure Treated Lumber Weights

Overview

Engineering reference data for Green Kiln Dried Pressure Treated Lumber Weights in material science and properties.

Key Formulas

Stress

$\sigma = \frac{F}{A}$

Force per unit area.

Strain

$\varepsilon = \frac{\Delta L}{L_0}$

Change in length per original length.

Hooke's Law

$\sigma = E \varepsilon$

Stress proportional to strain in elastic region.

Thermal Expansion

$\Delta L = \alpha L_0 \Delta T$

Length change due to temperature.

Variables

Symbol	Description	Unit
$\sigma$	Stress	Pa
$\varepsilon$	Strain	—
$E$	Young's modulus	Pa
$\alpha$	Thermal expansion coefficient	1/°C
$\Delta T$	Temperature change	°C

Key Definitions

• Nominal vs. Actual Dimensions: The listed dimensions (e.g., 2x4) are nominal sizes, not the actual physical dimensions of the lumber after milling.
• Moisture Content: The weight of lumber is directly dependent on its moisture content. "Green" lumber is freshly cut and wet, "kiln dried" has been dried in a kiln to a low moisture content, and "pressure treated" lumber has been infused with chemical preservatives, which adds significant weight.
