Difference of European and American Standard Steel Profile

1. Standard difference

European Standard and American Standard are two different standard systems. European Standard steel adopts European Standard (EN), while American Standard steel adopts American Standard (ASTM).

There are some differences between these two standards in terms of structure, size, chemical composition and mechanical properties.

2. Specification difference

European Standard steel generally starts with cross-sectional size and model, such as HEA300, IPE500, etc.; while American Standard steel usually starts with tolerance, such as W8x10, C6x8.2, etc.

There are also some differences in material marking and cross-sectional size. For example, European Standard steel often uses millimeters as the unit of length, while American Standard steel often uses inches.

3. Chemical composition

The chemical composition of European Standard steel and American Standard steel may differ in the content of some elements. The content of these elements will directly affect the performance and application range of the steel.

4. Strength and bearing capacity

The strength and bearing capacity of European Standard steel and American Standard steel may differ. Different standards have different requirements for the strength and load-bearing capacity of steel according to different application needs and differences in regional standards.
