Storage system

A storage system comprising:

• a storage grid structure;
• and
• a remotely operated storage bin handling vehicle,
• wherein the storage grid structure comprises 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,
• wherein the first and second type storage column profiles are interconnected at top ends thereof by rails forming a horizontal rail grid upon which the remotely operated storage bin handling vehicle may move in two perpendicular directions,
• wherein the first type of storage column profiles has a cross-section comprising a hollow centre section and four corner sections, each of the four corner sections of the first type of storage column profiles comprises two perpendicular bin guiding plates for accommodating a corner of a first storage bin,
• wherein the second type of storage column profiles has a cross-section comprising a hollow centre section having at least two connecting elements arranged in, or on, an external surface of the hollow centre section, and at least one corner section, the at least one corner section of the second type of storage column profiles comprises two perpendicular bin guiding plates for accommodating a corner of a second storage bin,
• wherein the storage grid structure comprises a grid supporting structure comprising at least two of the second type of storage column profiles interconnected, via the at least two connecting elements of the at least two second type of storage column profiles, by vertically inclined support struts,
• wherein each of the vertically inclined support struts comprises a first connecting end and a second connecting end for interconnecting the at least two of the second type of storage column profiles via the corresponding connecting elements, and
• wherein each the first and second connecting end has a hole connecting the first and second connecting end to an attachment recess of one of the second type of storage column profiles by use of a T-bolt.
