A storage system includes a storage grid structure and multiple remotely operated storage bin handling vehicles. The storage grid structure includes a first and a second type of vertical storage column profiles defining multiple storage columns in which storage bins can be stored one on top of another in vertical stacks. The storage column profiles are interconnected at their top ends by rails forming a horizontal rail grid upon which the bin handling vehicles may move in two perpendicular directions. The first type of storage column profiles has a cross-section comprising a hollow centre section and four corner sections. Each corner section includes two perpendicular bin guiding plates for accommodating a corner of a storage bin. The second type of storage column profiles has a cross-section comprising a hollow centre section having at least two connecting elements, and at least one corner section. The corner section includes two perpendicular bin guiding plates for accommodating a corner of a storage bin. The storage grid structure includes a grid supporting structure including at least some of the second type of storage column profiles interconnected, via their connecting elements by vertically inclined support struts.
