Glulam (glue-laminated timber) is an engineered wood product used for structural construction applications. Wagner Metal Supply uses glue-laminated timber sourced from Titian Timbers for beams and columns to construct our pole barn kits. Glue-laminated timber provides extra strength, weather protection, and extended longevity for structures. Not all pole barn kits are created quite the same. Some pole barn constructions use traditional timber for their beams and columns. Traditional timber can do the job, so why do we use glue-laminated beams? Here is why!
