A cantilever is a type of storage racking, featuring columns and high-strength cantilevers, suitable for storing various elongated materials, ring-shaped materials, sheet materials, and irregular shapes. The cantilevers can extend forward in a single or double-sided configuration, offering a lightweight structure with excellent load-bearing capacity, up to 1000kg per arm. The specially reinforced column structure can withstand pressures of 2000 to 3000kg. The design incorporates a rear pull to enhance overall racking stability, features easy installation, and comes with complete accessories. The modular design includes columns with rear pull for increased stability, high-strength cantilevers (which can be single or double-sided), and boasts a lightweight structure, good load-bearing capacity, and high space utilization. Adding shelves makes it particularly suitable for small, low-height storage rooms, with easy management and a wide view, offering higher utilization than conventional shelf racking. It can be categorized into lightweight, medium-duty, and heavy-duty based on load capacity.
