Abstract
A bamboo laminated lumber is provided having structural characteristics meeting or exceeding dimensionally equivalent wood based components. The bamboo laminated lumber is formed from bamboo laminated elements laminated and joined together to form dimensional lumber and engineered lumber components. The bamboo laminated lumber element comprises a combination of linear bamboo starter boards being halves of timber bamboo canes pressed flat with the inner pith surfaces laminated together with the grain aligned and skewed bamboo starter boards being halves of timber bamboo canes pressed flat with the inner pith surfaces laminated together with the grain offset from centerline at a specified angle. Top and bottom linear bamboo starter boards are laminated to a central skewed bamboo starter board yielding a bamboo laminated lumber element.
