Teak Lumber

Product Overview

Industrial-grade Tectona grandis lumber processed for structural marine, architectural millwork, and outdoor manufacturing applications. Sourced from sustainably managed plantations and processed through automated kilns to ensure strict dimensional stability, high natural rubber/oil content, and predictable machining performance. Supplied directly to OEMs, boatbuilders, and millwork fabricators in export-ready volumes.

Product Types & Options

Rough-Sawn Lumber

Unsurfaced boards intended for secondary re-sawing, custom rip-cutting, and specialized millwork profiling.

S4S / E4E Lumber

Surfaced four sides with eased edges, precision-planed to exact thickness and width tolerances for immediate assembly or finishing.

Decking Profiles

Custom-milled teak deck boards featuring pre-cut caulking grooves (rebates), tongue-and-groove joints, or shadow-gap profiles.

Component Blanks

Precision-cut dimension stock sized specifically for furniture components, stair treads, and marine handrails to minimize shop waste.

Material & Wood Characteristics

Botanical Identification: Tectona grandis (True Teak).

Natural Extractives: High concentration of natural tectoquinone and rubber oils, rendering the wood naturally resistant to marine borers, fungal decay, and acid degradation without chemical treatment.

Density: Average dry density of 650 to 750 kg/m3 at 12% moisture content.

Dimensional Stability: Low volumetric shrinkage coefficient; exhibits minimal movement across seasonal humidity shifts once properly seasoned.

Workability: Contains silica causing moderate tool dulling; high-speed carbide tooling recommended. Glues and finishes reliably despite natural oil content when surfaces are freshly prepared.

Specifications & Grades

Moisture Content (MC): Kiln-dried (KD) to a uniform 10% to 12% (+/- 2%) core reading.

Grain Configuration: Primarily quarter-sawn (vertical grain) options available to maximize linear stability and wear resistance for decking; flat-sawn available for decorative panel matching.

Grading Standards:

First European Quality (FEQ): Clear, defect-free faces, minimum 80% heartwood, strictly quarter-sawn options for high-stress marine use.
Select & Better: Clean faces suitable for visible architectural millwork and furniture components.
Dimensional Tolerances: Thickness: -0 / +1.0 mm; Width: -0 / +2.0 mm; Length: +25 / +50 mm overtrim.

Processing & Surface Options

Kiln Drying Protocol

Low-temperature, computerized schedule designed to relieve internal stresses, prevent case-hardening, and preserve natural oils.

Surfacing Capabilities

Multi-head planer-moulders operating at controlled feed speeds to eliminate tear-out on figured grain.

End-Sealing

Wax-coated ends applied immediately after cross-cutting to prevent end-checking and moisture re-absorption during transit.

Applications

Marine Decking

Yacht cockpit soles, swim platforms, and cap rails requiring slip resistance and saltwater durability.

Architectural Millwork

Exterior cladding, louver systems, door thresholds, and window framing exposed to extreme weathering.

Outdoor Furniture

Heavy-duty structural components for commercial and residential garden furniture.

Manufacturing & Quality Control

Inspection Stages

100% manual grading pass combined with automated moisture meter scanning at three points across each board length prior to bundling.

Defect Control

Rejection of boards exhibiting pith, severe surface checks, insect holes, or sapwood exceeding allowable thresholds per grade rule.

Packaging Specifications

Stacked on dimensional dunnage, interleaved with moisture-barrier wrapping, banded with heavy-duty steel straps, and protected with reinforced edge guards for containerized ocean freight.

Customization & OEM / Supply Options

Custom Dimensions

Fixed-width sorting, random-length or fixed-length tallies, and custom mouldings machined to CAD drawings.

Phytosanitary Treatment

Heat Treatment (HT) compliant with international export standards.

Chain of Custody

Supply documentation supporting timber legality and harvest origin upon request.

Selection Guide

For Marine Decking: Specify Kiln-Dried, FEQ grade, 100% quarter-sawn, thickness 25 mm or 32 mm, moisture content 10%-12%.

For Furniture Manufacturing: Specify Select & Better grade, mixed grain or flat-sawn for panel layout efficiency, rough-sawn or S4S depending on in-house machining setups.

For Exterior Architectural Cladding: Specify precise thickness tolerances and equilibrium moisture content targets matching regional installation climates.

FAQ

Q: How is moisture content verified prior to container loading?

A: Every unit is tested using multi-pin resistance meters inserted to core depth across representative boards per bundle. Readings are documented in a pre-shipment inspection report matching the specific bundle numbers.

Q: What is the exact percentage of heartwood in FEQ grade teak?

A: FEQ (First European Quality) material guarantees a minimum of 80% to 90% heartwood on the face, with zero allowance for soft sapwood on exposed wear surfaces.

Q: Are the lumber bundles treated for international export compliance?

A: Yes. All solid wood packaging materials, dunnage, and lumber shipments undergo compliant heat treatment, backed by official phytosanitary certification.

Q: Can you supply fixed-length tallies instead of random lengths?

A: Yes. Fixed-length sorting is available for specific cutting bills, subject to a nominal sorting surcharge and prior agreement on available inventory distribution.

Q: How do you prevent end-splitting during long ocean transits?

A: All boards are end-trimmed and sealed with a specialized wax emulsion immediately after surfacing to block rapid moisture exchange through exposed end-grain pores.

Q: What documentation is provided to verify legal timber origin?

A: Shipments include commercial invoices, packing lists, Bill of Lading, phytosanitary certificates, and origin documentation confirming compliance with regional timber regulatory frameworks where applicable.
