Chengal
Scientific name: Neobalanocarpus heimii
Overview
Chengal is a highly durable Southeast Asian hardwood known for its strength, resistance to decay, and long service life in exterior environments. Native primarily to Malaysia, it has been widely used in bridges, heavy construction, and marine applications.
Because of its durability and density, Chengal is often considered one of the most reliable structural hardwoods in the region.
Quick Facts
- Common Name: Chengal
- Scientific Name: Neobalanocarpus heimii
- Region: Asian Hardwoods (Southeast Asia – Malaysia & Indonesia)
- Tree Size: 100–150 ft tall, 3–5 ft trunk diameter
- Average Dried Weight: 53 lbs/ft³ (850 kg/m³)
- Janka Hardness: 1,870 lbf
- Color: Yellowish brown to medium brown, darkening with age
- Grain: Typically interlocked
- Texture: Medium to coarse
Identification Characteristics
Chengal is identified by its light to medium brown heartwood and moderately coarse texture. The grain is typically straight, though slight interlocking may occur. The wood is dense and heavy, with good structural integrity.
Sapwood is lighter and clearly differentiated from the heartwood.
Key identification traits include:
- ULight to medium brown heartwood
- Medium to coarse texture
- Straight to slightly interlocked grain
- Dense, heavy feel
Working Properties
Chengal is durable and strong but can be moderately difficult to work.
- Machines well with sharp tools
- Good dimensional stability
- Strong fastener holding ability
- Pre-drilling recommended
- Excellent weather resistance
It performs well in demanding structural environments.
Safety Note
Dust from Chengal may cause skin or respiratory irritation in some individuals. Proper dust extraction and protective equipment are recommended during machining and sanding.
Common Uses
Chengal is widely used in heavy-duty and exterior applications, including:
- Bridges
- Marine structures
- Exterior decking
- Heavy beams
- Structural frameworks
Its durability makes it especially valued in tropical climates.
Sustainability & Notes
Chengal has faced harvesting pressure due to its structural value. Availability may be limited depending on regulation and sourcing region. Responsible procurement is encouraged.
