Support bar for tube shelving – reinforcement and securing of the shelving structure. The support bar in tube shelving is used to stabilize and strengthen the shelf uprights, especially in setups with few shelves or when combining multiple shelving bays. It ensures the construction remains stable and stands securely, even under heavier loads or when the shelving is open-faced. In addition, the support bar can be used to support the products themselves – either mounted at the rear of the shelf to prevent items from sliding backward, or on the side to create a boundary and keep products in place.
