We designed and implemented a 29,000m² metallic mezzanine floor with a floor area over 2 levels and load bearing of 250 kg/m2 for the entire mezzanine floor. We also designed and installed an automated system to move items with a storage/delivery capacity of 250,000 hanging garments and 7,700,000 folded garments, as well as a delivery capacity to 1,160 destinations simultaneously.
