Teak Log

Product Overview

Raw teak logs (Tectona grandis) sourced from managed plantations, optimized for primary timber processing, marine construction, and architectural millwork. Featuring high natural oil content, dense grain structures, and a high heartwood-to-sapwood ratio to ensure minimal shrinkage and dimensional stability for downstream machining.

Product Types & Options

Sawlogs (Grade A)

Straight, cylindrical logs intended for high-yield primary sawing, slicing, and veneer production.

Marine Grade Logs

Selected specifically for boatbuilding and decking applications, characterized by straight grain and strict natural defect thresholds.

Rough-Round Logs

Unprocessed round timber scaled by mid-diameter and length for custom sawmill operations.

Custom Length Formats

Cut-to-length options ranging from 2.0m to 6.0m based on shipping requirements.

Material & Wood Characteristics

Natural Oil & Rubber Content

High concentration of natural tectoquinone and rubber compounds, providing inherent resistance to marine borers, fungi, and weathering.

Density

Dry density ranges between 650 kg/m3 to 750 kg/m3 at 12% moisture content.

Dimensional Stability

Low volumetric shrinkage coefficient; minimal movement under fluctuating relative humidity and temperature.

Color Profile

Golden-brown heartwood that darkens upon UV exposure to a uniform teak patina; distinct pale-yellow sapwood.

Specifications & Grades

Diameter Range (Mid-Diameter under bark): 30 cm to 60+ cm.

Length Options: 2.0m, 3.0m, 4.0m, 5.0m, 6.0m (with standard +5cm to +10cm trimming allowance).

Grading Standards: Sorted by diameter, straightness, end-split severity, and knots according to tropical hardwood export rules.

Heartwood Ratio: Minimum 85% heartwood content across cross-sections for structural and marine applications.

Processing & Surface Options

End-Sealing

Log ends are treated immediately after cross-cutting using water-based end-grain sealer to prevent rapid moisture loss and end-splitting.

Bark Status

Available as debarked (for phytosanitary export requirements) or with natural bark intact depending on transit duration and processing schedule.

Moisture State

Green (freshly felled) or air-dried logs available based on client milling schedules.

Applications

Marine Engineering

Teak decking, caprails, and structural framing for vessels.

Architectural Millwork

Custom window frames, exterior cladding, doors, and louvers.

Outdoor Infrastructure

Bridge components, boardwalks, and marina furniture.

Furniture Manufacturing

Premium indoor and outdoor furniture components requiring high weather resistance.

Manufacturing & Quality Control

01/

Log Scaling & Measurement: Diameter measured at mid-length under bark using standard metric calipers; length measured strictly between cut ends.

02/

Defect Inspection: Manual inspection for ring shake, heart rot, insect bore holes, and excessive taper.

03/

Phytosanitary Treatment: Heat treatment or fumigation compliant with international standards available upon request for international shipping.

04/

Chain of Custody: Full documentation tracking harvest permits through processing facilities, backed by standard certificate of origin and trade compliance records.

Customization & Supply Options

Volume Capacity

Full Container Load (20'GP/40'HC) and breakbulk shipment arrangements.

Grading Specification

Tailored sorting based on specific minimum mid-diameter and maximum allowable taper.

Documentation Support

Issuance of Certificate of Origin, Phytosanitary Certificate, and legal timber harvesting verification documents.

FAQ

Q: What is the minimum order quantity (MOQ) for teak logs?

A: Standard MOQ is one 20-foot container (20'GP), typically volumetric weight ranging from 18 to 22 cubic meters depending on log dimensions and port regulations. Breakbulk shipping is available for larger project volumes.

Q: How are the log ends protected against splitting during transit?

A: All logs are coated with a specialized polymer end-sealer within 4 hours of cross-cutting to seal the vascular tissues, reducing moisture evaporation rates and preventing end-splitting during long sea freight transit.

Q: What legal and compliance documentation is provided with each shipment?

A: Every shipment includes the Bill of Lading, Certificate of Origin, Phytosanitary Certificate (standard compliant), and local harvest/export permits verifying legal source compliance.

Q: How is the volume of the teak logs measured?

A: Volume is calculated using standard metric formulas (such as Smalian's formula or true cubic measurement based on actual mid-diameter under bark and exact length) to ensure transparent commercial settlement.

Q: Can logs be inspected prior to container loading?

A: Yes. Third-party inspection agencies are welcomed at our log yards for pre-shipment inspection covering dimensions, grading, quantity verification, and phytosanitary checks.

Q: What is the typical moisture content of the supplied logs?

A: Logs can be supplied in a fresh-cut (green) state or air-dried condition. For green logs, moisture content typically ranges between 50% to 70% depending on heartwood density and seasonal felling time.
