What is the difference between steel structure HN and HW?
HN is called narrow flange H, which is only H steel with a flange width greater than or equal to 2, mainly used for beams.The use of I-beam is equivalent to that of HN steelWH270*250*18*23 is welded to type H steel. W is the first letter of welding.
HM is called mid flange H section steel. It is H steel with a flange width ratio of 1.33-1.75. It is mainly used as steel frame column in steel structure, and is used as frame beam in the frame structure which is subjected to load, such as equipment platform.
Distinction: H type steel is welded, HM, HN and HW are hot rolledHW is a wide flange of H steel, H steel and the height of the flange width is basically the same, mainly used in steel frame structure of steel column, also known as reinforced steel columns in the steel structure is mainly used for the column.
