The load-bearing capacity of lightweight laminated shelves is divided by type, and the scope is as follows: Lightweight shelving: Single layer load-bearing capacity of 50-200kg, suitable for small and lightweight goods such as stationery and small electronic accessories. Medium sized shelves: Single layer load-bearing capacity of 200~500kg, suitable for box loading of goods and small and medium-sized components (such as food boxes and small household appliances). Heavy duty shelving: Single layer load-bearing capacity of 500~1500kg (higher for customized models), used for storing heavy equipment and large industrial products (such as molds and mechanical parts). The load-bearing capacity is affected by the material (steel is superior to wood), structural design, and even placement of goods. Overloading should be avoided during use.
