What is the difference between lean pipe and iron pipe?

There are significant differences between lean pipe and iron pipe in terms of material structure, application scenarios, performance characteristics, and cost-effectiveness. Lean pipe adopts steel plastic composite, stainless steel or aluminum alloy structure, which has the characteristics of lightweight, corrosion resistance, and repeatable assembly. It is mainly used for building industrial flexible production lines; Iron pipes (ordinary steel pipes) are mainly made of a single metal material, focusing on construction and heavy-duty scenarios. ‌‌

1、 Differences in material structure
Lean management:
Composite material: outer layer is PE/ABS plastic layer, middle metal layer (steel or aluminum alloy), inner layer is rust proof coating. ‌‌
Standardized dimensions: outer diameter of approximately 28mm, wall thickness of 0.7-2.0mm, and weight 30% -50% lighter than iron pipes. ‌‌
Iron pipe:
Single material: mostly carbon steel or alloy steel, without outer protection.
Diverse specifications: With a wide range of diameters, the wall thickness is usually greater than that of lean pipes, and the load-bearing capacity is stronger. ‌‌
2、 Comparison of application scenarios
Lean management:
Industrial field: flexible equipment such as assembly workbenches, logistics turnover vehicles, and production line shelves. ‌‌
Applicable industries: automotive manufacturing, electronic assembly, biomedicine, and other scenarios that require frequent adjustments to production layout. ‌‌
Iron pipe:
Construction engineering: water/gas pipelines, building structural support. ‌‌
Heavy industry: scenarios that require high strength and high pressure resistance, such as petrochemicals and machinery manufacturing. ‌‌
