What is the difference between American Standard Flat Steel Bar A36 and Chinese National Standard Flat Steel Bar Q235B?

Although American Standard Flat Steel and National Standard Flat Steel are similar on the surface, there are some important differences in practical application, mainly focusing on the following aspects:

FLAT BAR

Material:

American Standard flat steel is usually made of carbon steel as the main raw material, with higher carbon content and stronger hardness, which is suitable for bearing greater pressure and weight. The national standard flat steel is made of low carbon steel, with good toughness and plasticity, suitable for occasions with lower requirements for material strength.

Size:

The size of American Standard flat steel is usually labelled according to imperial units, such as 1/8 inch, 1/4 inch, etc., while the national standard flat steel is labelled using metric units, such as 3mm, 4mm, etc..

Process:

American standard flat steel is usually produced by cold drawing process, high surface finish, relatively high dimensional accuracy. National standard flat steel is more hot rolling process, the surface is not as smooth as cold drawn flat steel, but the cost is lower.

Application areas:

Due to the high hardness of American Standard flat steel, it is usually used in engineering and construction, machinery manufacturing and heavy equipment to withstand high power and load. While GB flat steel is commonly used in light industry and home decoration, such as manufacturing furniture, railings, shelves and so on.

In addition to these few major differences, there are some subtle but possibly overlooked differences that need your attention. For example, during processing and installation, American Standard flat steel may require stronger equipment and technical support due to its higher hardness, while GB flat steel is easier to cut and process.
