Tree square have started in 2012 by seeing the potential for what is considered well-design object which could elevate architectural spaces and landscape.

In the first decision, we started to extend the product from our base GRP Septic Tank Industries, PROUD ASIA CO., LTD. who considered to be Fiberglass expert for over 20 years.

The GRP Septic Tank are normally located underground or on ground in the open air area for decades. It's known to be durable to sunlight, rain and moisture. That's why we selected GRP (Glass Reinforced Plastic) as the primary material according to its enduring qualities and unique physical properties to create unique objects.

With our ongoing commitment to research and development, our skilled craftsman have put a year of experience working and developing fiberglass works though each production process from crafting the prototype, create the mould until the paint finish it gives life to a collection of objects and furniture which maintain the sculptural expression and handicraft.
