Pacific Oak, also known as Kembang Semangkok (Scaphium spp.), is a versatile Southeast Asian light hardwood with warm yellow-brown to light buff tones and a straight to shallowly interlocked grain that creates an attractive, subtle figure. It offers reliable strength, good stability, and excellent machining properties—making it easy to work with for precise stair components. Ideal for interior stair treads, risers, stringers, handrails, and balustrades, Pacific Oak provides a clean, elegant look with natural warmth that suits modern, coastal, or contemporary Queensland designs. Its cost-effective performance and smooth finish make it a practical choice for durable, stylish stair systems that age beautifully.
