Why Teak
Teak (Tectona grandis) is one of the most durable structural woods in the world. Its performance comes from naturally occurring molecular compounds within the wood structure.
These compounds include:
Tectoquinones
Phenolic extractives
Natural oils
Together they contribute to exceptional resistance to biological degradation, dimensional stability and long-term durability in challenging climates.
Technical Data Highlight:
Average density ≈ 580 kg/m.
Integrated Manufacturing Platform
TRH integrates the entire structural timber value chain, from certified forestry to precision fabrication. This vertical integration ensures consistent quality, traceability and structural reliability.
The Journey
“[h4]Controlled Biological Input
TRH systems begin with FSC-certified plantation teak (Tectona grandis). Controlled forestry enables predictable material behavior, unlike mixed natural forests.

“[h4]Base Material Performance
Teak is a high-performance hardwood with durability and dimensional stability. Clear wood properties define the baseline for engineered structural behavior.

“[h4]Chemical Performance System
Natural extractives within teak act as internal protection mechanisms against biological degradation. These compounds enhance resistance to fungi, moisture, and environmental exposure over time.

“[h4]Structural Material Conversion
Logs are converted into structural boards through controlled sawmilling. Fiber orientation and geometry directly influence structural performance.

“[h4]Moisture State Engineering
Boards are kiln-dried to 9–12% moisture content. Moisture directly impacts dimensional stability and adhesive performance.

“[h4]Structural Classification System
Boards are classified before lamination based on structural criteria. Grading reduces variability and defines performance consistency.

“[h4]Continuous Lamella Engineering
Short boards are joined into continuous lamellas using finger joints. Finger joints enable continuity while eliminating localized defects.

“[h4]Structural Bonding Platform (EPI)
Lamellas are bonded using EPI adhesive systems. Bonding defines whether the system behaves as one structural element.
