Structure: It's a modular, multi-tier unit with two adjacent bays. The boltless design (indicated by the slotted uprights and clip-in beams/braces) makes for easy assembly and disassembly.
Frame Material: The frame (uprights and support beams) is made of steel or a similar strong metal alloy, which provides durability and high load capacity.
Color: The uprights are a prominent blue, and the horizontal beams and shelves are a light grey/silver. This color combination is common for visibility and professionalism in industrial settings.
Shelves: It features five adjustable shelf levels per bay (a total of 10 shelf levels across the two bays shown). The shelves themselves appear to be steel panels (decking) for maximum strength and easy cleaning, unlike units that use particleboard or wire deck.
