Titan Timbers glue laminated wood columns use #1 SYP (Southern Yellow Pine) lowers for their superior treatability. Permanent two part Phenol Resorcinol adhesive is cured under 120 psi pressure. No mechanical fasteners are needed to secure a Titan Timber Glue laminated column. Total face gluing resists individual ply separation, assuring that every column withstands warping and twisting. Titan Timbers glue laminated columns use SPF (Spruce-Pine-Fir) uppers which provide the best strength-to-weight ratio for the building trade. Tool and machine friendly, our SPF laminated columns cut, screw, nail and notch quicker and easier, to save you time and money.
