Profile Steel

Stainless steel channel is a long strip of steel with a groove-shaped cross-section. The same as I-steel, stainless steel production of stainless steel groove

Steel is also divided into ordinary channel steel and light channel steel, the model and specification of the same as the waist height (h)× leg width (b)× waist thickness (d) of the mm, such as 120×53×5 channel steel, that is, the waist height of 120mm, round steel, need to be added on the right side of the model a, b, c and so on to distinguish. Usually, the stainless steel channel indicates its model with the number of centimeters of the waist height, and the above channel is called 12# channel steel. Channel steel specifications range from 5 to 40#. Including and marking requirements in accordance with GB2101-80 provisions.

(1) Hot rolled stainless steel ordinary channel steel (GB707-88) Main uses: Ordinary channel steel is mainly used in building structures, vehicle manufacturing and other industrial structures, often used with I-steel.

(2) Hot rolled stainless steel light channel steel (YB164-63) Hot rolled light channel steel is a kind of steel with wide legs and thin walls, which has better economic effects than ordinary hot rolled channel steel. Its specifications range from 5-40#. The 1966 standard specifies specifications ranging from 10-40#. Main uses:

Construction and steel frame structure.

The commonly used stainless steel channel materials for stainless steel production are: 201, 202, 301, 304, 321,000, 316,316L, and special materials can generally be customized.

Numbering and representation of channel steel

① Use the international chemical element symbol and the national symbol to indicate the chemical composition, and use the Arabic alphabet to indicate the component content:

For example: China, Russia 12CrNi3A

② Use fixed digit numbers to represent steel series or numbers; Such as: United States, Japan, 300 systems, 400 systems, 200 systems;

③ Use the Latin alphabet and order to form the serial number, only to indicate the purpose.
