Precast concrete Arrow panels have been supplied and installed by ACP (Concrete) Ltd for Potter Logistics, at their storage facility at Melmerby, near Ripon. In Jan 2012 Nick Brighty, General manager for Potter Logistics, contacted ACP regarding a bulk storage problem - within an existing building there was a requirement for various bunkers with a combined total capacity of approx. 10,000 tonnes to store bulk products such as grain & rice prior to processing and packaging. The issue was to devise a layout that accommodated bunkers of various capacities, the processing facility, vehicle flow and the existing structure and doorways.
