Luli Precision OSB is a next-generation oriented strand board known for its exceptional durability, dimensional stability, and environmental excellence. Crafted from 100% imported radiata pine, including small-diameter logs and wood processing by-products, it maximizes the use of renewable resources while delivering reliable structural strength and a refined surface finish.

Produced using Canada Kadant Camara 28/81 long-strand flakers and Germany Dieffenbacher’s advanced forming and one-step hot-pressing system, this OSB ensures superior bonding strength, consistent density, and improved structural precision — far exceeding conventional two-step-formed boards.
