Galvanized Steel Definition and Common Material Introduction

Galvanized steel refers to the ordinary steel after processing and surface treatment, coated with a layer of zinc on the surface to enhance the corrosion resistance and beauty of the steel.

Galvanized steel refers to the ordinary steel after processing and surface treatment, coated with a layer of zinc on the surface to enhance the corrosion resistance and beauty of the steel. Galvanized steel process is divided into hot galvanizing and cold galvanizing two kinds, of which hot galvanizing is the steel surface soaked in heated zinc liquid, so that it forms a layer of zinc iron alloy on the surface, more durable; Cold galvanizing is to spray a layer of zinc on the surface, which is more economical and practical.

Common galvanized steel material:

1. Q195: is a kind of low carbon steel material, poor strength and ductility, suitable for some general occasions, such as general buildings, Bridges, etc.

2. Q215: The carbon content is slightly higher than Q195, but the strength, ductility and other physical properties are slightly better, suitable for light steel structure, automobile manufacturing, boilers, buildings, etc.

3. Q235: high carbon content, good strength and toughness, widely used in reinforced concrete structures, large pressure vessels, shipbuilding, aviation, automobiles, Bridges and other fields.

4. Q345: belongs to the medium carbon steel material, high strength, widely used in Bridges, power towers, shipbuilding, automobiles, ladder steel frame, bearings, mechanical parts and so on.
