H-shaped steel beam is a common structural steel, its section shape is similar to the capital English letter "H". This kind of beam is usually used in the structure of buildings and Bridges because it has high strength and stiffness and can withstand large loads.

Hot dip galvanizing is a common anticorrosive treatment method, by dipping the steel into the molten zinc liquid, the zinc and the steel surface chemical reaction, forming a solid layer of zinc iron alloy layer. This layer of alloy can effectively prevent the steel from contact with the external environment, thus extending the service life of the steel.

Hot dip galvanizing treatment on H-shaped steel beam can further improve its corrosion resistance, so that it can maintain good performance under harsh environmental conditions. In addition, hot dip galvanizing also has a certain aesthetic effect, because the zinc layer has a good gloss.

In short, after hot dip galvanizing treatment, H-type steel beam not only has excellent mechanical properties, but also has good corrosion resistance and aesthetics, so it has been widely used in many projects.
