Lumber is already wood, so protecting it from impact sounds redundant. What actually damages a lumber bundle in transit is the band: steel or PET strapping tensioned over a sawn edge crushes the corner, opens the band line and, on dressed or planed stock, leaves a mark that turns a graded bundle into a downgraded one.
What fails on a lumber bundle
The strapping cuts into the sawn edge and the band loosens as the fibres compress. Once loose, the bundle shifts and the bind is gone.
On planed or moulded stock the band leaves a compression line along the face, which is a visible defect on the outer boards.
At the ends, the bundle takes knocks during loading and the end grain splits.
Specification at a glance
Lumber bundles are long and heavy, so the protector is long, and the leg is chosen to spread the band rather than to protect the face. Length follows the bundle width at each band position, not the bundle length.
| Bundle | Protector | Note |
|---|
| Bare, banded | At each band, both edges | Band interface |
| Wrapped | Under the wrap | Wrap holds it |
| Planed stock | Wider leg | Protects the face line |
| Green lumber | Band interface only | Will soften |
| Export, kiln dried | Full band positions | Long sea leg |
Banded, wrapped or both
Bare bundles take protectors at each band position on all four long edges that the band crosses. That is usually two edges per band, not four.
Where the bundle is also wrapped, the protector goes under the wrap so the wrap holds it. Wrapping first and pushing protectors underneath defeats both.
Green, kiln dried and export
Green lumber is heavy and wet, and a paper protector will take on that moisture. Where the bundle is green, the protector is a band interface rather than a moisture measure, and it will soften.
Kiln dried and export bundles are the better fit: dry stock, dry protector, and a band that has to hold its tension across a long sea leg.
Where the destination requires treated wood packaging, a paper protector is not wood packaging and does not change the bundle mark. That is a point in its favour.
Questions buyers ask before ordering
Does lumber need edge protection?
For the band, yes. Untreated strapping crushes the sawn edge and loosens.
How long should the pieces be?
Long enough to cover the bundle width at each band position.
Under or over the wrap?
Under, so the wrap holds the protector in place.
Is it suitable for green lumber?
It will soften. Use it as a band interface, not as moisture protection.
Does it affect ISPM 15?
No. A paper protector is not wood packaging and does not change the bundle mark.
