Reclaimed & Pallet Lumber Buying Guide
Nominal vs. actual sizes, species, grades, and industrial uses
The lumber sold on Repackify is not the premium kiln-dried retail stock at a home center. It is reclaimed and pallet-grade dimensional lumber — deck boards, stringers, cut stock, and mixed-dimension pieces recovered from pallet repair operations, decommissioned pallets, and industrial surplus. This material is priced for function, not finish, and it is exactly what pallet manufacturers, freight packers, and industrial buyers need when cost and availability matter more than appearance.
Key takeaways
- Nominal lumber sizes are not actual sizes.A 2×4 measures 1.5″×3.5″; this is not a defect — it is the industry standard after drying and surfacing.
- SPF (spruce-pine-fir) is the dominant pallet softwood — light, available, and cost-effective. SYP (Southern Yellow Pine) is denser and stronger for heavy-duty pallet and crate framing.
- KDHT (kiln-dried heat-treated) lumber satisfies ISPM-15 export requirements and is required for pallet components going into export crates or pallets.
- Reclaimed pallet lumber is sold by the board, bundle, or truckload — price per board foot drops sharply at bundle and truckload volume.
Nominal vs. actual lumber dimensions
Every buyer encounters this: you order a 2×4 and receive a board that measures 1.5″×3.5″. This is not a mistake. Lumber is sold by its nominal size— the rough-sawn dimension before the mill dries and surfaces (planes) the wood. Drying removes moisture and causes shrinkage; surfacing (S4S — surfaced four sides) removes another ⅛″–¼″ per face for a smooth, consistent dimension. The resulting actual size is what you measure on the delivered board.
| Nominal size | Actual size (in) | Common pallet use |
|---|---|---|
| 2 × 4 | 1.5 × 3.5 | Stringers, blocking, crate framing |
| 2 × 6 | 1.5 × 5.5 | Heavy stringers, base framing |
| 1 × 4 | 0.75 × 3.5 | Deck boards (standard pallet) |
| 1 × 6 | 0.75 × 5.5 | Wide deck boards, sheathing |
| 5/4 × 4 | 1.0 × 3.5 | Heavy-duty deck boards |
| 4 × 4 | 3.5 × 3.5 | Corner posts, crate legs |
Pallet lumber components
Most reclaimed pallet lumber falls into three specific component types, which is how suppliers grade and sort it:
Stringers
The three longitudinal members that run the full length of a stringer pallet. Standard GMA stringer spec is a 2×4 (actual 1.5″×3.5″) at 48″ long, often with notches cut for partial 4-way forklift entry. Stringers take the most abuse in pallet handling and are the most commonly replaced component in pallet repair. See pallet stringers for sale for current inventory.
Deck boards
The boards nailed across the top (and bottom, on double-face pallets) perpendicular to the stringers. Standard GMA deck boards are a 1×4 (0.75″×3.5″) or 5/8″×3.5″, 40″ long. The two outermost boards are called lead boards; they take the most forklift blade impact and wear out first. See pallet deck boards for sale.
Blocking and dunnage
Cut stock in various dimensions used for blocking (securing cargo from movement), bracing (preventing shift in transit), and dunnage (void-fill between cargo layers). Typical dimensions: 2×4 and 4×4 cut to length, 1″–2″ thick shims, and wedges. Recycled pallet components are cost-effective dunnage because dimensional accuracy matters less than soundness and strength.
Species: softwood vs. hardwood
Most pallet and reclaimed lumber is softwood — specifically SPF or SYP — because softwood pallets dominate North American production. Hardwood pallet lumber (mixed oak, poplar, ash) appears in the recycled market mainly from older pallets, specialty manufacturers, and furniture industry waste.
| SPF (softwood) | SYP (softwood) | Mixed hardwood (oak, etc.) | |
|---|---|---|---|
| Specific gravity | 0.42–0.45 | 0.51–0.59 | 0.60–0.75 (oak ~0.68) |
| Weight (lb/board ft) | ~2.0–2.3 | ~2.5–3.0 | ~3.0–3.8 |
| Nail holding (relative) | Good | Better | Best |
| Relative cost (reclaimed) | Lowest | Low–moderate | Moderate–high |
| Best uses | Standard pallets, light dunnage | Heavy-duty pallets, crate framing | Heavy pallets, blocking, crafts |
SPF(spruce, pine, and fir species grouped together by grading agencies) is light and easy to nail, making it the default for standard pallet production. Its lower specific gravity (~0.43) means a 48×40 SPF stringer pallet weighs roughly 33–40 lb — light enough to handle manually.
Southern Yellow Pineis significantly denser and stronger — modulus of rupture around 14,500 psi versus ~9,400 psi for white spruce — and resists splitting better under repeated nailing, which matters for pallet repair. SYP pallets weigh 5–10 lb more than equivalent SPF pallets, a real factor in high-cube air freight.
Grades and KDHT for export
Reclaimed pallet lumber is graded by soundness, not appearance. A “sound” board is free of cracks, splits, or decay that would compromise its load-bearing function; cosmetic staining, nail holes, and minor surface checks are acceptable. Suppliers typically sort into two tiers: pallet-grade (structural, may have cosmetic defects) and off-grade / firewood (checked, split, or decayed — not structural).
KDHT— kiln-dried heat-treated — means the lumber has been dried in a kiln to a moisture content of 19% or below and heat-treated to meet ISPM-15 (56°C core for 30 continuous minutes) in the same process or separately. KDHT is required for any pallet or crate component that will cross an international border. The IPPC mark stamped on KDHT lumber (or on the finished pallet) is what customs inspects — unstamped wood can be seized or ordered back. See the pallet buying guide for full ISPM-15 context.
How reclaimed lumber is sold
Reclaimed pallet lumber is sold three ways: by the board (useful for small repair runs), by the bundle(typically 50–200 pieces sorted by dimension, banded or strapped), and by the truckload (mixed or sorted, priced per thousand board feet). Price per board foot drops sharply at bundle and truckload volumes — buying a truckload of 1×4 deck boards typically costs 30–50% less per piece than buying individual boards from a dealer.
