The Importance of Galvanised Metal in Industries

  • Steel has been the backbone of many industries in some of the most advanced countries in the world and South Africa is no different. There are many steel manufacturers and distributors operating in the South African market offering numerous variants of steel and steel components for use in several industries and manufacturing sectors. One of the major examples include Steel and Pipes for Africa, offering various commercial and specialised grades of steel.  However, people can have a tough time selecting the nature of steel. Galvanised steel is a popular option among consumers, because of the notable advantages it provides. (Information Credit –


    Galvanisation on steel involves the process of applying a protective zinc coating to prevent premature rust and corrosion. Galvanised steel is thus used for the construction or repairing of steel structures to mainly benefit from the low maintenance and repair costs that it provides. Some additional benefits include:


    1. Protection: Without galvanisation, steel is susceptible to atmospheric conditions over time, and experiences rust. Although there are various ways to increase protection such as painting or plastic coating, none of them are as effective as galvanisation. Galvanised steel products give them an extended life because of the slow corrosion rate of zinc. A popular method is hot-dip galvanisation which involves all the material to be dipped into molten zinc.


    2. Low Cost: As compared to other corrosion resistant steel variants such as stainless steel, galvanised steel is significantly less costly. Thus, it is used by medium to small scale manufacturing services as well.


    3. Coating Protection: Zinc corrosion rates are far less than normal steel which protects the base metal through cathodic protection.


    4. Durability: Galvanised steel with zinc coating is exceptionally resistant to any external mechanical damage because of its structural hardiness.


    5. Protecting Small Areas: Galvanisation prevents smaller and weaker parts of a steel structure from exposure to the atmosphere. As a result, rust is eliminated for steel parts which are structurally weaker than others.


    How to Choose a Distributor or Supplier:

    There are certain factors that can be used to make this decision. Some of them are listed below:

    1. Reputation: Always make sure the company you’re choosing has ample experience and a good reputation in the market. Both these factors ensure that the company is legitimate and has conducted operations in the market for a long period of time. Thus, the likelihood of receiving lower quality steel is reduced.


    2. Licensing and Certification: Steel products are certified and licensed by regulatory bodies on both a national and international level. The regulations are in place for quality assurance and are granted after careful examination of each product. Thus, companies which provide unlicensed or uncertified steel products should be avoided at all costs.


    Final Thoughts:

    In South Africa, there are several suppliers who claim to provide the best quality steel components available at affordable prices. However, the quality of materials you receive will depend on the distributor chosen. Thus, only the most legitimate and reputed dealers and distributors should be chosen when galvanised steel is concerned.
