Timber Selected According to Species and Application

Timber properties vary significantly between species. Density, grain structure, shrinkage, hardness, natural durability, workability and appearance all influence whether a particular timber is appropriate for a specific product.

For international buyers, the timber specification should therefore identify the species or commercial timber group, required dimensions, grade, moisture condition and intended application.

PT TATA SUMBER INTI supplies timber for further manufacturing rather than treating all wood species as interchangeable. Species-specific requirements can be reviewed before production and quotation.

Timber Manufacturing

From Timber Selection to Finished Wood Components

Sawn timber performance depends not only on species but also on the condition and processing of the material. Sawing direction, drying, final dimensions, machining and grading can all influence the suitability of timber for its intended use.

Production requirements can therefore be defined according to the buyer's application rather than using one generic specification for every species.

Species Selection

Timber is selected according to the required physical, mechanical and appearance characteristics.

Sawn Dimensions

Thickness, width and length are established according to the product or manufacturing requirement.

Moisture Requirement

Moisture requirements should be specified according to the destination climate and final application.

Further Processing

Where required, timber can be prepared for subsequent machining, profiling or component production.

Selected Timber Species

Indonesian Timber Species Portfolio

The following technical information is based on published timber references and is presented as species-level reference data. Actual commercial timber properties can vary according to species, origin, growth conditions, grade, moisture content and processing condition.

1. Pine Timber

Pinus merkusii Junghuhn & de Vriese

Timber Applications

Timber for Doors and Wood Manufacturing Projects

Timber can be further processed into components for doors, architectural woodwork and other manufactured wood products. The appropriate species should be selected according to dimensional stability, machining, appearance and end-use requirements.

Wooden Door Components

Selected timber can be processed into components for solid wooden doors and related joinery. Species selection should consider moisture condition, dimensional movement, machining and finishing requirements.

Architectural Wood Projects

Timber products can be prepared for project-based architectural and interior applications where species, dimensions and finishing requirements are established before production.

Manufacturing Approach

Why Specify Timber Directly with the Manufacturer?

Species-Specific Specification

Timber is evaluated according to the actual species or commercial group instead of applying one generic technical specification to every wood type.

Custom Dimensions

Buyers can provide required thickness, width and length specifications for quotation and production review.

Application-Based Selection

Species selection can be discussed according to the intended application, including furniture, doors, flooring, decking and other wood products.

OEM & Project Supply

Timber can be specified as raw sawn material or as a component for further customer manufacturing, subject to production capability and agreed specifications.
