Q355GNH Structural H Beam
Q355GNH H Beam Material
Q355GNH h shaped beam is divided into four grades of Q295GNH, Q355GNH, Q265GNH and Q310GNH according to the standard.
Q355GNH h shaped iron beam is weathering steel. q stands for yield; its yield strength is 355MPa; GNH stands for high weathering.
Q355GNH h shaped iron beam high weathering steel is 2~8 times of plain carbon steel and 1.5~10 times of plain carbon steel in painting. At the same time, it is rust-resistant, so that the components of corrosion resistance and life extension, thinning and consumption reduction, labor-saving and energy saving features.
Q355GNH h type steel beam is mainly used for steel structure which is exposed to the atmosphere for a long time, such as railway, vehicles, bridges, pylons, etc. Q355GNH high weathering steel is used for the manufacture of containers, railway vehicles, petroleum derricks, seaport buildings, oil platforms, and chemical and petroleum equipment in the container and other structural parts of the container containing hydrogen sulfide corrosive medium.
