Grain storage structures - also known as the bins, or wheat bins in local popular usage - are grain silos spread around Western Australia, primarily in the wheatbelt region, at grain receival locations.
Historically they have been linked with the Wheatbelt railway lines of Western Australia, and the transport of grain to the ports of Western Australia for export by the CBH Group.
In 2003, CBH published a document "Co-operative Bulk Handling Ltd's grain storage system in Western Australia".
Historically there were structures found at Midland/Bellevue, it was a rail based storage facility, and at Fremantle and Bunbury there were grain storage silos that were part of the port loading facilities - they are not included in this list.
The identification of the types of installations was made as follows:
The Perth based Metro Grain Centre is located on Abernethy Road in Forrestfield.
It is connected by road and rail with the port in Fremantle, for container shipping, and Kwinana port for bulk handling of grain.
It was built in 1998 at a cost of $120m, and can store 200,000 tonnes of grain.
At Fremantle and Bunbury, historically significant silos were constructed in the 1930s.
Built on the North Quay in 1948 and demolished in 2000 the North Quay, Port of Fremantle wheat silos were considered heritage.
Bunbury grain silos were built in 1937, were decommissioned in the 1980s, and have been re-styled as accommodation since 1994.
