Tali Wood Decking
Tali wood is a very dense, durable, and strong tropical hardwood from West and Central Africa, known for its natural resistance to decay, insects, and wear. It is commonly used for heavy-duty outdoor applications like decking and marine construction.
Properties & Characteristics
Tali wood (scientific names Erythrophleum suaveolens or Amphimas pterocarpoides) has several key properties that make it suitable for demanding projects.
- Color: The heartwood is a light yellowish-brown to a rich orange or reddish-brown when fresh, which darkens to a darker brown or golden hue with exposure to light and air.
- Grain & Texture: It features an interlocked, straight grain and a uniformly coarse texture.
- Durability: Tali is highly durable (Class 1 durability against decay) and resistant to rot, fungi, termites, and dry wood borers, making it an excellent choice for outdoor use without chemical treatment.
- Density & Strength: It is a heavy, hard to very hard wood with a high density (around 47 lbs/ft³ or 750 kg/m³) and a Janka hardness of 2,920 lbf.
- Workability: Due to its high density and interlocked grain, it can be difficult to machine and has a blunting effect on tools, so pre-drilling is often necessary. It glues and finishes well, however.
Common Uses
Tali wood’s strength and durability make it ideal for a variety of heavy-duty applications.
- Decking & Flooring: It is a popular, sustainable choice for decking and high-traffic flooring in public spaces due to its high wear resistance.
- Construction: Tali is used for frameworks, bridges, railway sleepers, and heavy hydraulic constructions.
- Marine Applications: Its resistance to moisture makes it suitable for boat building, marine construction, and harbor/dock work.
- Other Uses: It also finds application in furniture, cabinetry, interior trim, and veneer.
Tali Wood vs. Teak Wood
For someone with an interest in teak, the comparison is useful. Tali and Teak are both highly durable tropical hardwoods, but they have some differences.
| Property | Tali Wood | Teak Wood |
| Color | Yellow-brown to reddish-brown, darkens to dark brown. | Golden to medium brown heartwood. |
| Durability | High (Class 1); naturally resistant to rot, fungi, insects. | Very high; high natural oil content provides exceptional resistance to moisture and pests. |
| Density | High (~47 lbs/ft³ / 750 kg/m³) | Medium-high (~41 lbs/ft³ / 655 kg/m³) |
| Grain | Interlocked, coarse texture. | Generally straight, with occasional interlocking. |
| Janka Hardness | 2,920 lbf | 1,070 lbf |
| Machinability | Difficult; high blunting effect on tools. | Easier to work with, but high silica content can still dull tools. |
While Tali wood is significantly harder and more dense, both are excellent, durable choices for outdoor and heavy-wear applications, with Teak being traditionally seen as the gold standard for yacht construction due to its unique oil content and stability.
