Magna Beams are produced by a licenced manufacturer from small pieces of Merbau/ Kwila timber using a durable, structural glue. They are ideal for use in structures where the beauty of a rich red/brown hardwood is to be expressed or where superior strength is required. They can be used in exposed external environments including bush-fire prone areas and are resistant to termites. They stay straighter and are available in longer lengths than solid timber beams. Refer to Magna Beam Span Tables.
