Galvanised Square dowel Bars are steel bars that serve the purpose of spreading positive load across joints. They are designed smooth which assists with allowing them to move in the joint when shrinkage occurs due to temperature changes etc. They allow for a reduction in joint deflection. Dowel Bars are installed between concrete slabs to allow for the load to transfer between them as well as allow for movement (horizontal) because of expansion. They provide a corrosion-resistant and highly durable solution for connections in concrete slabs and other applications.
