Introduction
Our 1x3 Teak Boards (nominal size) are a versatile staple for high-end craftsmanship. Milled from genuine Tectona grandis, these boards are surfaced on all four sides (S4S) to a consistent finish, making them ready for immediate use in professional woodworking and marine projects.
While thicker lumber is used for structural beams, the 1x3 profile is the industry standard for detailed trim work, furniture slats, and decorative architectural accents. Each board is selected for its high heartwood content, ensuring the natural oils that make teak world-famous are present in every linear foot.

Why Choose 1x3 Teak Boards?
Optimal Stability for Thin Profiles
Narrower boards like the 1x3 are susceptible to warping if not dried and milled correctly. Our teak boards undergo a slow-kiln process that "locks" the fibers in place. This dimensional stability is critical when installing long runs of trim or cabinetry where alignment must remain perfect over time.
Natural Resistance to "Checking"
Unlike many other hardwoods, teak has a low shrinkage coefficient. In the 1x3 dimension, which is often used for exterior slats and louvers, this means the wood is far less likely to develop surface cracks (checking) when exposed to cycles of intense sun and heavy rain.
Marine-Grade Performance
The 1x3 profile is one of the most common sizes used in boat building. Whether it is used for cap rails, handrails, or cockpit trim, these boards offer the necessary oil density to withstand constant saltwater exposure without deteriorating or requiring chemical preservatives.
High-End Aesthetic Appeal
1x3 boards are frequently used in modern "slat wall" or "batten" designs. The rich golden-brown hue and sophisticated grain of our teak provide a luxury finish that domestic softwoods or composite materials cannot replicate.

FAQ: 1x3 Teak Board Selection
Q: What is the "actual" size of a 1x3 board?
A: In the lumber industry, "1x3" is the nominal size. After the drying and surfacing (S4S) process, the actual dimensions are typically 3/4" thick by 2-1/2" wide. If your project requires a full 1" thickness, please inquire about our "Rough Sawn" 5/4 stock.
Q: Can I use these boards for DIY repair of garden furniture?
A: Yes. These boards are the most common size used for the slats on high-end teak benches and chairs. They are easy to cut to length and pre-drill for stainless steel fasteners.
Q: Do I need to oil 1x3 boards immediately?
A: It depends on the look you want. If the boards are for indoor use, you can leave them unfinished or use a clear wax. For outdoor use, you can let them weather to a silver-gray, or apply a UV-rated teak sealer within two weeks of installation to maintain the golden color.
Q: Is there a minimum order for 1x3 boards?
A: We cater to both small custom projects and large commercial orders. You can purchase these by the linear foot or in bulk bundles.
Q: Are these boards "Clear All Heart"?
A: Our Grade A / FEQ boards are selected to be virtually free of sapwood and knots. This ensures maximum longevity, as only the heartwood contains the essential oils needed for weather resistance.
