On March 14, 1987, PT. Trimitra Karya Mandiri opened its doors to the public for the first time. Specializing in the application of aluminum doors and windows, our company had two business objectives:

1. To be the best choice in aluminium and metal based products.

2. Build an organization based on commitment, excellence and integrity.

Trimitra Karya Mandiri began receiving recognition in the 90s when it introduced its own aluminium product line under the same two principles. While the times have changed, believing and practicing these philosophies have allowed our company to operate stably and at the same time to continuously expand in Indonesia. We have become a manufacturer and applicator of premium and economy aluminium doors & windows, security screen doors and windows, garage doors, curtain walls, canopies, shower screens, and aluminium composite panel.
