If rattan and lampit represent the woven softness of South Kalimantan, kayu ulin shows its solid, heavy side. Ulin, often called “kayu besi” (ironwood), is famous across Kalimantan for its exceptional durability – sources note that properly used ulin can last for decades and is highly resistant to rot and termites.
In South Kalimantan, ulin is widely used for meja–kursi (tables and chairs), doors, windows, gates, and other structural elements, and is often offered in thick, solid, non-jointed slabs for premium furniture.
Recent craft initiatives also highlight furniture and décor made from ulin offcuts and waste, turning leftover pieces into unique chairs and tables while raising awareness about the need to use this slow-growing timber wisely.
The signature of South Kalimantan’s ulin furniture is:
-
Visibly dense grain and dark brown to reddish-black tones
-
Heavy, solid construction suitable for outdoor terraces, lobbies, and statement pieces
-
A narrative about heritage and sustainability, especially when made from reclaimed or waste ulin
Combined with rattan and lampit, kayu ulin gives South Kalimantan a complete natural-material palette: woven, flexible, and soft on one side; dense, structural, and enduring on the other.
