Automated storage system required for store in Hungary

We have two options in mind:
1. storage of metal sheets in our existing storehouse (which is 25 m x 12 m x 4 meter in dimensions),
sheet size: 1500x3000 mm, max. loading capacitiy of one storage compartment: 3 tons, altogether we need appr. 200-250 compartments.
2. you suggest us a complete storage system, with its dimensions, and we build a new warehouse accordingly.
