Building materials Galvanized steel

Galvanized steel is a widely used material in the field of construction, it is usually used in the construction of building exterior walls. For example, in the design of glass curtain walls, marble curtain walls and aluminum curtain walls, galvanized steel is often used as a column and force material to ensure the stability and durability of the building. In addition, galvanized steel is often used in outdoor telecommunications towers, highways and other open-air construction projects to provide necessary structural support and protection.

Galvanized steel is called galvanized steel because it is covered with a layer of zinc metal after a special treatment process. This galvanized layer can effectively prevent the steel from being affected by corrosion and oxidation, thus extending the service life of the steel. According to different treatment methods, galvanized steel can be divided into two types: electric galvanized and hot dip galvanized.

Electrogalvanizing is to immerse the steel in the electrolyte containing zinc ions, and zinc ions are deposited on the surface of the steel through the action of current to form a galvanized layer. This method is suitable for small sizes of steel or where precise control of the thickness of the galvanized layer is required. Electrogalvanizing has the advantages of low cost and easy operation, but the adhesion of the coating is relatively weak.

Hot dip galvanizing involves dipping steel into a molten zinc pot and coating the zinc layer evenly on the steel surface through high temperature. This method is suitable for large sizes of steel or the need for thicker galvanized coating occasions. Hot-dip galvanizing has the advantages of strong coating adhesion and high corrosion resistance, but the cost is relatively high.

In short, galvanized steel as an important building material, plays an important role in building exterior walls, telecommunications towers, highways and other open-air construction projects. The galvanized layer can effectively protect the steel from corrosion and oxidation, and extend the service life of the steel. Whether it is electric galvanizing or hot dip galvanizing, it provides reliable structural support and protection for construction projects.
