What is the difference between the third generation and the first generation of Lean pipe?

What is the difference between a substitute wire rod and a first generation wire rod? The material of the third-generation wire rod is aluminum alloy, but the first generation wire rod is a steel plastic composite pipe with an outer layer of PE, ABS or ESD plastic layer. Below, GL editor will popularize it for everyone!

1、 The material of the wire rod is different
The first generation wire rod (also known as lean tube or plastic coated tube) is a steel plastic composite tube composed of the following structures:

Outer layer: PE, ABS or ESD plastic layer
Intermediate layer: metal layer (usually high-quality steel pipe)
Inner layer: Anti rust coating
The standard diameter is usually 28mm, and there are various specifications of wall thickness such as 0.8mm, 1.0mm, 1.5mm, 2.0mm, etc.

The third-generation wire rod is made of aluminum alloy lean tube, while ordinary lean aluminum tube is made of dovetail groove lean tube.

2、 Application Fields
Wire rods are widely used in the following fields:

Material shelves: storage shelves, gravity shelves, mobile shelves, etc
Workbench types: anti-static workbench, lifting workbench, detection workbench, etc
Turnover vehicles: anti-static handcarts, tool carts, testing turnover vehicles, etc
Production line categories: U-shaped flexible production line, automotive assembly production line, electronic product assembly line, etc

4、 Comparison of Technical Parameters
According to product data from e-commerce platforms:

First generation wire rod: price range of 7.15-15 yuan/meter, wall thickness of 1.0-1.2mm, material of steel plastic composite.
Third generation wire rod: price range of 12.75-30.67 yuan/meter, wall thickness of 1.5-1.7mm, material of aluminum alloy.
Some high-end third-generation wire rod products can be priced up to 3600 yuan per set, suitable for special industrial scenarios.

5、 Choose Suggestions
Limited budget and simple requirements: choose a generation of wire rods to meet basic storage and workbench needs;
High strength and durability requirements: Choose third-generation wire rods, suitable for long-term use and complex environments;
Special industrial applications: Consider professional grade third-generation wire rod products, such as special functional models with locking rotors.
