Q355NH Material H Beam

 

 

Q355NH h shaped beam is weathering steel, the implementation of international GB/T4171-2008 standard, Q355NH h beam material grade classification: Q355NHA, Q355NHB, Q355NHC, Q355NHAD.

 

Q355NH steel beam h in the letter Q that is steel yield strength "yield" initial capital letters; the number 355 that the lower limit of the yield strength of steel is not less than 355 MPa; the letter that is weathering steel "weathering" initial capital letters; the letter A Indicates that the steel quality grade or level.

 

Q355NH h type steel beam Application:
Used for steel structures that are exposed to the atmosphere for long periods of time, such as railroads, vehicles, bridges, and pylons. It can also be used in the manufacture of containers, railway vehicles, oil derricks, seaport buildings, oil platforms and chemical and petroleum equipment containing hydrogen sulfide corrosive media such as containers and other structural components.
