DIRECT FACTORY & EXPORT SUPPLIER
Indonesian Wooden Flooring & Decking
PT TATA SUMBER INTI supplies wooden flooring and decking manufactured according to customer requirements. Our product range includes selected Indonesian hardwoods and softwoods suitable for interior flooring, architectural applications, exterior decking and project-specific timber requirements.
Flooring and Decking Manufactured to Customer Specification
Wooden flooring and decking require more than attractive timber. Species selection, moisture condition, dimensional stability, machining profile, surface preparation and final installation environment all influence the performance of the finished product.
PT TATA SUMBER INTI works on a customer-order basis. Product dimensions, timber species, construction type, surface profile, grading requirements and finishing specifications can therefore be discussed according to the intended application and destination market.
Our portfolio includes Merbau, Meranti, Teak, Pine, Yellow Balau, Kumea, Mahogany and Jack Fruit Wood. If you require another wood species that is not listed on this page, please do not hesitate to contact us. We can review your requested species and production requirements.
Wooden Flooring and Wooden Decking
Different wood species and construction formats are selected according to whether the material is intended for interior flooring, covered architectural areas or exterior exposure.

Flooring & Decking Wood Species Portfolio
The technical values below are reference properties of the wood species. Actual finished-product performance depends on timber origin, grade, moisture content, machining, construction method, installation conditions and finishing system.
01. Pine
Pinus merkusii • SoftwoodSumatran Pine is a relatively lightweight softwood with straight grain, medium and even texture, and a light reddish-brown heartwood with pale sapwood. Its lower hardness compared with the heavy tropical hardwoods in this portfolio makes it more suitable for applications where a lighter timber and easier machining are required.
| Scientific Name | Pinus merkusii |
| Average Dried Density | Approx. 710 kg/m³ at 12% MC |
| Janka Hardness | Approx. 4,230 N |
| Modulus of Rupture | Approx. 96.4 MPa |

| HS Reference | 4407.29 for other tropical sawn wood exceeding 6 mm |
| Production | Made-to-order specification |
05. Kumea
Manilkara merrilliana • Heavy HardwoodKumea Batu, identified in Indonesian forestry literature as Manilkara merrilliana, is a very heavy and hard timber from Sulawesi. Published Indonesian forestry research reports a reddish-brown heartwood, straight grain, fine texture and high density, together with strong mechanical properties. These characteristics make Kumea a candidate for heavy-duty flooring and decking applications when the required machining and dimensional conditions are properly controlled.
| Scientific Name | Manilkara merrilliana |
| Air-Dry Specific Gravity | Approx. 0.92 average in published Indonesian research |
| Wood Character | Very heavy and hard |
