What kind of steel is used in steel structure?

Answer:

In general, Q235 is the most commonly used plant, followed by Q345., Q490 and other high strength steel, but not commonly used.I do steel structure design, often use Q235, and Q345.
Generally speaking, the corrosion resistance of the steel that has been corroded with corrosion-resistant material is 50 years, depending on the material of the brush, and also for 100 years.
It depends on the kind of steel structure. There are thousands of kinds or even thousands of kinds of steel. General steel construction refers to the construction of steelIf the construction of steel, then basically steel Q235, Q345, Q390, Q420 four kinds of steel. Q235 is plain carbon steel. The latter three are low alloy steels. Corrosion depends on the structure of the steel structure and the use of parts, ships, viaducts, a corrosion resistant period of more than 20 years, but not up to this standard, foreign countries are basically sprayed aluminum and zinc sprayed. Antiseptic method. The tall tower structure of the TV tower mast varies from 10 to 20 years. The general steel structure must basically be more than 5 years.
