Artificial access applies to goods, usually bearing the <1000KG / layer, low-cost, safe, reliable, assembly, demolition simple and can be used alone, may have free stitching way into various permutations. Two columns by shoring, diagonal bracing to form self-locking bolt connection, can effectively prevent loosening bolts triggered after shelf instability; Using beams of cold-rolled special about the P-type beam, and this structure is simple and reliable, light weight-bearing capacity, low cost features. Column-card and connect with a special design, safety pin; To ensure that the beams would not impact outside off; Laminates-how to strengthen tendons, a strong bearing capacity, wear resistance, replacement simple, low-cost maintenance characteristics. The shelf-films, beams, laminates, safety pin and plastic components feet at the end
