About Us


Establish in 1987, DON LOONG gradually becomes the primary granite supplier domestically that we have involved in a number of construction projects with significance such as numerous mass rapid transit stations and High-speed Railway Stations.

The factory is in an area of rough 8,000 ping and additional land occupying 10,000 ping outside is for original stone materials, which is also a contractor with the largest inventory of granite stone domestically. We keep introducing state-of-art equipments these years, also are one of factories with the largest capacity of granite domestically.

We introduced “diamond collar multi-saw” from Italy as a cutting machine for stone materials, with which the output is not only multiple times as traditional one, but also more environmental-protection, energy efficiency and being friendlier to environment. Hence, stone material manufacturers in Taiwan also introduced and applied it gradually, which reduces down environmental issues derived from production.

DON LOONG’s profound attitude toward service wins appraise in the circle and we expect to introduce more environment-friendly technology continuously, providing more environmental-protection, better quality, better service efficiency for clients.
