High weatherproof structural steel has corrosion resistance and prolonged service life by adding alloying elements such as Cu, Cr and Ni. Besides good weather resistance, they also have excellent low temperature impact toughness and are suitable for use in various extreme climates.
The Galvanized Structural steel melts the zinc ingot at high temperature, puts some auxiliary materials into it, and then immerses the structural steel in the galvanizing bath to make the structural steel adhere to a layer of zinc. The advantage of hot-dip galvanizing is its strong anti-corrosion ability, good adhesion and hardness of galvanized layer.The galvanized layer forms a special metallurgical structure which can withstand mechanical damage during transportation and use.
Hot-dip galvanizing has a long antiseptic life, but in different environments, the antiseptic life is different: 13 years in heavy industry zone, 50 years in ocean, 104 years in suburb, 30 years in city.With the development of industry, hot-dip galvanizing products have been used in many fields. The advantage of hot-dip galvanizing is that it has a long anti-corrosion life, and it has been a popular anti-corrosion treatment method to adapt to the environment widely. Widely used with electric power tower, communication tower, railway, highway protection, street lamp pole, marine components, building steel structural components, substation ancillary facilities, light industry and so on.
