Premium Southern Yellow Pine timbers offering unmatched strength-to-weight ratio for structural applications. Kiln-dried and surfaced on four sides (S4S), these #2 or btr, #3 and #4 grade beams combine load-bearing capacity with workability for both visible and concealed structural uses.
✅ Nominal Size: 4" x 6" x 8' ✅ Actual Size: 3.5" x 5.5" (varies slightly with moisture) ✅ Grade: #2 or btr, #3 & #4 (structural) ✅ Moisture Content: ≤19% (kiln-dried) ✅ Surface: Smooth S4S (ready for finishing) ✅ Certification: SFI/PEFC sustainable forestry
Untreated pine timbers can be used for a wide array of construction or other building project uses. Southern Yellow Pine (SYP) has the highest density of all structural lumber species, providing superior fastener-holding power and load-bearing capacity. The natural wood appearance of untreated timbers makes them easy to paint or stain to achieve the desired finish look.Untreated pine timbers can be used for a wide array of construction or other building project uses.

Excellent quality straps
Posted on March 15, 2023
These straps have held up perfectly through months of heavy use on our construction site. The ratchet mechanism is smooth and the webbing shows no signs of wear.

Great value for the price

I've used these for securing equipment on my flatbed trailer. They work as well as more expensive brands I've tried. The only reason I didn't give 5 stars is that the handles could be slightly more ergonomic.

Good basic straps

These straps do the job well for general use. I've had no issues with them, though I haven't pushed them to their limits yet. The yellow color makes them easy to spot in my tool trailer.

Superior strength-to-weight ratio vs treated wood - ideal for dry applications where preservatives aren't needed.
3.5" x 5.5" is standard for kiln-dried dimensional lumber - all engineering calculations use this measurement.
Not recommended untreated - request pressure-treated option for outdoor/exposed applications.
#3 has tighter knot restrictions (better appearance) while maintaining identical structural ratings.
Minimal movement thanks to kiln-drying - proper storage (flat, dry) prevents twisting.
