What are the applications of lightweight storage shelves in small warehouses
Lightweight storage shelves, with their lightweight structure, flexible installation, and cost-effectiveness, play a core role in efficient storage and space optimization in small warehouses. The following is an explanation from the aspects of application scenarios, type characteristics, layout design, and selection points:
1、 Core application scenarios and functions
1. E-commerce and Retail Warehousing
Small item sorting and storage: such as clothing, 3C accessories, daily necessities, etc., are stored in layers using lightweight shelving with a load-bearing capacity of 50-150kg per layer. They are paired with tags to achieve rapid SKU sorting.
Temporary stocking area: During the e-commerce promotion period, pre-sale products are temporarily stored, and the shelves can be flexibly combined (such as 2 meters high x 0.6 meters wide x 1.2 meters deep) for easy manual retrieval and placement.
2. Manufacturing line side warehouse
Temporary storage of parts: The mechanical processing workshop stores standard parts such as screws and bearings, and the shelves are equipped with drawer style partitions (to prevent falling), which are coordinated with kanban management to achieve entry and exit.
Intermediate product transfer: such as temporary storage of PCB boards after SMT process in electronic factories. The shelves are made of anti-static materials (spray coated steel plates), and the interlayer spacing can be adjusted (to adapt to different sizes of pallets).
3. Logistics distribution transfer station
Package distribution and storage: Express delivery outlets use lightweight attic shelves (upper storage, lower operation) to access packages using elevators, increasing storage capacity by over 30% per square meter.
Regional classification: Store packages in different areas according to delivery routes, and label shelves with area codes (such as "A area - east of the city") to improve sorting efficiency.
4. Commercial and service warehousing
Supermarket back warehouse replenishment: Convenience store back warehouses use lightweight angle steel shelves to store snacks and beverages, with the floor height designed according to the height of the cardboard box (such as a 24 can cola box with a height of 30cm and a layer spacing of 35cm).
Medical drug storage: The pharmacy is equipped with a light metal shelf next to a cool cabinet to store non refrigerated drugs, which meets GSP certification requirements (ground clearance ≥ 10cm, wall clearance ≥ 5cm).
3、 Layout design strategy for small warehouses
1. Space utilization optimization
Wall mounted arrangement method: The shelves are arranged in a straight line along the warehouse wall, leaving a 1.2-1.5-meter passage in the middle (suitable for manual hydraulic trucks), suitable for rectangular warehouses (such as those below 200 square meters).
Partition modularization: Divided according to the "purchasing area storage area sorting area shipping area", the storage area is combined with lightweight shelves to form a U-shape or L-shape, shortening the handling path.
2. Human Machine Engineering Design
Golden height principle: Commonly used goods are stored at a height of 1.2-1.6 meters (the most easily accessible area for the human body), light goods are stored at a higher level (requiring climbing stairs), and heavy goods are stored at a lower level (at least 0.5 meters above the ground).
Channel width calculation: single person passage ≥ 0.8 meters, handcart passage ≥ 1.2 meters, if using an electric forklift, it needs to be ≥ 2.5 meters (light shelves usually do not require forklifts, manual handling is the main method).
3. Flexible design
Scalable combination: Using standard size shelves (such as width 0.9 meters/1.2 meters), it can be horizontally spliced according to inventory growth to avoid one-time excessive investment.
Temporary partition function: Some lightweight shelves (such as angle steel shelves with backboards) can also serve as warehouse partitions, dividing office and storage areas.
4、 Key points of selection and installation
1. Confirmation of core parameters
Load bearing requirement: Calculated based on the weight of a single box of goods. For example, if each box of goods weighs 50kg and 2 boxes are placed on each layer, the single-layer load capacity of the shelf needs to be ≥ 100kg (with a 20% safety factor reserved).
Warehouse net height: Shelf height ≤ Warehouse net height -0.5 meters (with reserved lighting and ventilation space). If the warehouse is 3 meters high, it is recommended to choose shelves below 2.5 meters (with a climbing ladder).
2. Material and process selection
Main material: Q235B cold-rolled steel plate (high strength) is preferred, and the surface is electrostatically sprayed (rust resistant, suitable for environments with humidity ≤ 80%).
Special environment adaptation: Choose galvanized shelves (rust proof) for damp warehouses, and food grade spray coating (compliant with ISO 22000 standard) for food warehouses.
3. Installation and safety regulations
Ground flatness: Before installing the shelves, use a level to check the ground with an error of ≤ 5mm/meter. Otherwise, adjust with iron pads to avoid tilting the shelves.
Anti dumping measures: Shelves with a height of ≥ 2 meters should be fixed to the ground with expansion bolts, or adjacent shelves should be connected in series with connecting rods (seismic intensity ≥ 6 degrees).
5、 Typical Industry Application Cases
1.3C E-commerce Warehouse (500 ㎡):
Adopting a shelf style shelving system (2.4 meters high x 0.6 meters wide x 1.2 meters deep), divided into zones for mobile phones, accessories, and chargers, with 4 turnover boxes (box weight ≤ 30kg) placed on each floor, paired with PDA scanning and sorting, with a daily order processing capacity of over 2000.
2. Hardware and Building Materials Convenience Store (100 ㎡):
Install cantilevered shelves against the wall (with a single-sided cantilever length of 0.5 meters) to store pipes (2-3 meters long), use angle steel shelves in the middle area to store screws, nails, and other small items, and install a stopper at the top to prevent goods from slipping off.
3. Chain Pharmacy Distribution Center (300 ㎡):
Adopting attic style shelves (with a lower height of 1.8 meters and an upper height of 1.2 meters), the lower layer is stored according to the classification of drugs (such as colds and antibiotics), and the upper layer is used to store inventory and stock. Fire isolation doors are installed at the staircase entrance (in compliance with fire safety requirements).
