Ulin (ironwood)

Extremely dense Borneo ironwood—decades of outdoor life for decking, sirap, and pool details even under harsh sun.

Ulin (ironwood) is an exceptionally dense Indonesian hardwood. It is so durable that submerged freshwater applications are common in traditional construction.

For villas, ulin is a gold-standard choice for outdoor decking, sirap roofing, and pool-adjacent details that must survive harsh UV and wet-dry cycling for decades—assuming ethical sourcing and permitted harvest documentation.
