The number of Concrete Batch Plant aggregates needed to store on sight continue to increase as engineers source concrete aggregates for high profile projects.  No longer is it enough to have the 4 basic materials of sand, 3/8", 3/4" and 1-1/2".  Communicating to the delivery driver and confirming to the plant operator that the correct material is being transfered into the applicable storage bin has become a greater priority.  Using high display LED lights that can be seen clearly regardless of the sun reflection are now standard equipment for a CON-E-CO Concrete Batch Plant.
