NLT is composed of layers of lumbers jointed with steel nails. As steel cannot be cut by saws for lumbers, it is difficult to cut NLT with saws normally used for lumber processing. To make it possible to process NLT by the lumber saws, NLT composed of nails made of aluminum was produced and tested for its out-plane bending properties. The bending strength and stiffness of the NLT composed of aluminum nails were almost equivalent to that of NLT composed of steel nails. NLT was modeled to verify the ratio of bending and rotation of the butt jointed lumbers.
