PT. Sumatera Timber Indo Industry

Integrated Timber Company

We are committed to guaranteeing quality of services

Sumatera Timber Indo Industry (STI) was established in the second millennium by three veterans in the timber industry. Combining the breadth of their knowledge and network, our founders capitalized on the growing demand in the European Market for high quality specialty doors during the early 2000s.

Using locally sourced Indonesian hardwood species such as Merbau (Latin: Intsia or commonlyknown as Malaccan Teak) and Red Meranti (Latin: Shorea or commonly known as Meranti), our doors were manufactured to KOMO quality mark (highest quality standard mark for European building industry).
