The difference between the third and second generations of Lean Management

The core difference between the third-generation wire rod and the second-generation wire rod is that the material has been upgraded to aluminum alloy, the structure is lighter, the load-bearing capacity is stronger, and the connection is more convenient. Here is a specific comparison:

1. Material and surface treatment

Second generation wire rod: made of stainless steel or chrome plated steel pipe, with high surface smoothness and certain anti-corrosion performance, but with a large weight.
Third generation wire rod: Made of aluminum alloy material, the surface is anodized to form a dense oxide film (with a thickness of over 10 μ m), achieving permanent corrosion and rust prevention while significantly reducing weight.

2. Weight and handling efficiency

The unit weight of the third-generation aluminum alloy wire rod is only about half of that of traditional steel wire rod (aluminum tube 369g/m vs steel tube 520g/m), greatly reducing the burden of transportation and assembly.

3. Connection method and structural stability

Second generation: relying on external card connectors, installation is cumbersome, overall rigidity is average, and scalability is limited.
Third generation: Adopting embedded connection structure and die cast aluminum connectors, the connection is more secure, the structure is close to lightweight industrial aluminum profiles, the stability is greatly improved, and it supports repeated disassembly and assembly.

4. Carrying capacity and application scope

The third generation wire rod single set frame can bear up to 500kg, suitable for high-end manufacturing scenarios such as medium and heavy material transportation, automated production lines, AGV peripheral equipment, etc.
The second generation is mainly used in the pharmaceutical and food industries that require light load and high cleanliness, with relatively low carrying capacity.

5. Environmental protection and recyclability

The third-generation wire rod has no resin coating, is green and environmentally friendly, has a high aluminum recycling rate, and complies with ROHS standards.
The second generation has a relatively complex recycling process due to the presence of metal coatings.

6. Appearance and maintenance

The third generation is silver white in color, with an elegant and generous appearance. The surface is not easily aged and does not require additional maintenance.
Although the second generation has been improved, there may be wear or rust on the coating after long-term use.
