Manilkara solid screening is a highly durable, dense hardwood (often sold as "Pacific Jarrah" or "Bulletwood") known for its vibrant reddish-brown color, excellent resistance to decay and insects, and suitability for outdoor projects.
Key Features
- Exceptional Durability: Manilkara heartwood is rated as Class 1 for above-ground use and Class 2 in-ground, indicating a life expectancy of over 15-25+ years in exposed conditions. It is very resistant to decay fungi and highly resistant to subterranean termites.
- Aesthetic Appeal: The heartwood color ranges from light to dark reddish-brown and tends to darken with exposure to light, offering a rich, premium look to screening projects. It has a fine, uniform texture and a low to medium luster.
- High Density and Strength: The wood is very hard and heavy, with an air-dry density of approximately 1030 kg/m³. This high density contributes to its strength and wear resistance.
- Stability: It is typically kiln-dried (KD) to enhance stability, which minimizes warping and splitting when properly seasoned.
- Workability: Despite its high density and interlocked grain, Manilkara is moderately easy to work with modern equipment. However, pre-boring for nailing and screwing is necessary to prevent splitting.
- Minimal Leaching: A significant advantage of Manilkara compared to other hardwoods like Merbau is its minimal tannin leaching, reducing the risk of staining on adjacent surfaces like concrete.
Common Applications
- Privacy Screening & Fencing: Its durability and aesthetic make it an excellent choice for long-lasting, modern privacy screens and garden fences.
- Decking: Manilkara (often known as Massaranduba in North America) is a popular, highly durable option for decking due to its strength and resistance to decay.
- Heavy Construction: It is used for heavy construction, including bridge building, railway sleepers, and posts, even in contact with the ground or exposed to the weather.
- Other Uses: It is also used for flooring, outdoor furniture, joinery, and turnery.
Important Considerations
- Seasoning: Manilkara dries slowly, and careful seasoning (often kiln-drying is recommended) is necessary to avoid checking (cracking) and warping.
- Fixings: Pre-boring is required for all nailing and screwing due to the wood's hardness. The use of quality stainless steel or galvanised fixings is recommended to prevent rust stains.
- Toxicity/Irritation: The fine dust produced during machining may cause minor skin irritation or respiratory issues in some individuals. Proper protective equipment is recommended during cutting.
