What is a smooth sliding strip?

"Liulitiao" is an abbreviation for industrial aluminum alloy (or plastic) slide rails, consisting of a steel channel body and rolling wheels. It is a non-powered conveyor device that utilizes a 3%-9% inclination to achieve first-in, first-out (FIFO) through the self-weight of the cargo.

Core definition and structure - essence: A sliding track accessory specifically designed for warehousing and logistics, not a standalone shelf, and requires use with a frame.
- Composition: The main body is made of 6063-T5 aluminum alloy profiles (also available in sheet metal or plastic composite materials), with internally matched PE/ABS rollers forming a low-friction slideway.
- Principle: During installation, a 5%-9% drop is created. Goods are placed from the higher end and automatically slide towards the lower end by gravity for retrieval.
- Naming: derived from its characteristic of "smooth and agile" operation.

Key Features and Parameters - Functional Objectives: Implement mandatory first-in, first-out (FIFO) inventory management to prevent material backlog and expiration, and enhance sorting efficiency.
- Load-bearing capacity: A single roller can support up to 6kg, and multiple rollers connected in parallel can meet the transportation needs of large items.
- Specification: Common cross-sections include 38mm×35mm, with a standard length of 6 meters (cuttable), and the roller spacing is typically 150mm.
- Material iteration: The mainstream is aluminum alloy (high rigidity), and plastic/composite versions have emerged for light-load scenarios (low cost).

Main application scenarios: 1. Warehousing and logistics: sorting areas in distribution centers, flow-through racks, used in conjunction with turnover boxes/cartons.
2. Production and Manufacturing: Material chutes for automobile/home appliance assembly lines, and workshop line-side warehouse replenishment systems.
3. Special fields: distribution of sterile medical materials, and light-load sorting of electronic components (utilizing easy-to-clean or anti-static properties).
