Heavy-duty racks, also commonly known as beam racks or cargo racks, belong to the category of pallet racks and are the most common type of racking in various domestic storage racking systems. The fully assembled structure in the form of column pieces + beams has the characteristics of adjustable height, strong stability, and high space utilization. It is connected to the columns by snaps or bolts to form a stable support frame; the shelves are mostly steel mesh panels or wooden brackets, which can effectively disperse the pressure of goods and improve the overall bearing capacity. Heavy-duty racks are widely used in large enterprises, manufacturing warehouses, logistics distribution centers and other fields. Its strong load-bearing capacity and stable structure enable it to stably support the long-term stacking of various heavy commodities such as industrial raw materials, machinery and equipment, chemical products, etc., and effectively avoid safety accidents caused by deformation or collapse of the shelves.
