With the style of industrial design, our 5 Layers Boltless Shelving looks modern and sturdy. Also, the boltless design is creative and easy assembled. It is constructed of steel with galvanized surface in black, strong enough for the loading capacity of 175KG per layer. Not least, made of 4m thickness MDF board, 5 layers offer a ample storage space to you which you can collect things orderly.
