Steel is strong, durable and omnipresent in today’s commercial, residential and industrial worlds. However, it is subject to corrosion. One method of preventing this from occurring is to galvanize it. The sacrificial layer of zinc alloy coats the steel providing a protective layer. While different production methods are available, for many industries, hot dip galvanized steel sheets are perfect for their construction projects.
What Is General or Hot Dip Steel Galvanizing
This process of general or hot dip galvanizing dates back to the mid-18th century. However, it continues to evolve as new technology and advanced equipment improve upon the basic process. Essentially, hot-dip galvanizing involves taking the sheets of steel and actually immersing (dipping) them in a bath consisting of molten zinc. The reaction between the two metals at this temperature results in the formation of a uniform layer of zinc over the steel. This coating is responsible for the anti-corrosion protective qualities of galvanized steel sheets.
However, if the process is to be successful, it must adhere to two basic steps. Of this, the first one – pre-galvanizing is essential. This is a surface cleaning process. It requires taking the workpieces and cleaning them of all impurities. Both chemical and mechanical means are good options. An acid pickling is one method of achieving a clean piece of stainless steel sheet and, therefore, increasing the ability to create a good quality bond during the galvanizing procedure.
The second step is the actual galvanizing process. Following this, a third step can occur. This may be post-treatment and a rigorous inspection.
Galvanized Steel Sheets
Fabricators and metalworkers need durable, reliable sheet metal. If the application requires the use of steel, another characteristic will be anti-corrosive. Galvanized steel sheets meet these specifications. Moreover, using the hot-dip method proves to be economical as well for a variety of shapes.
