Beam type steel shelf structure system to support the main force components of the goods, through a specific beam-column node form (beam and column are connected by hooks, pins, bolts and welding, forming welded joints, bolt contacts, mechanical nodes) to form the shelf frame structure, here more semi-rigid nodes for processing, This is also one of the characteristics of the pallet beam type steel shelf that is different from the general steel structure.
