Merger of Australian Construction Products and Safe Direction

We are delighted to announce the merger of Safe Direction Pty Ltd and Australian Construction Products Pty Ltd (ACP).
On 1 May 2023 Jaybro, Australia’s leading supplier to the civil construction and infrastructure sector, and owner of ACP, purchased 100% of the share capital of Safe Direction. Under Jaybro’s ownership the two businesses will be merged to form Australia’s preeminent company manufacturing and supplying vehicle barrier systems.

A compelling motivation for the merger is the value created for our customers from combining the collective resources and knowledge of the two companies. Notably there will be significant broadening of the product range and enhancement to distribution reach and capacity. There will be transitionary steps as the two businesses assemble under the one entity, Safe Direction. Part of this transition includes the consolidation of the products and services offered by the merged business into a single web domain

We trust that this merger will provide increased value to you and we look forward to the opportunity to be of assistance.
