Galvanizing and Thriving: Elevating Your Project with Corrosion Protection


Galvanizing is the powerful shield against the relentless march of time and the harsh whispers of the elements that pose a constant threat to the integrity of our modernised structures. From towering skyscrapers and stock-feed structures to chicken coops and the humblest garden fence, corrosion gnaws away at untreated metals, compromising their strength and shortening their lifespans.


Fortified Embraces and the Understanding of Galvanizing


Galvanization is the process of coating a base metal, usually steel or iron, with a layer of molten zinc. This protective layer acts as a barrier against the environmental factors that cause corrosion, such as moisture, oxygen, and salt. The zinc, being more reactive than iron or steel, preferentially corrodes, sacrificing itself to shield the metal compounds underneath. This sacrificial protection extends the life of the steel significantly, often by up to 100 years or more.


The Science Behind Galvanizing


The sustainable life of galvanization relies on the electrochemical binding between zinc, steel, or other metals. When exposed to an electrolyte – like through rainwater or seawater – zinc ions dissolve more readily than steel ions. This creates an electrical current that flows from the zinc to the steel, further inhibiting the corrosion of the steel particles. As the zinc corrodes, it forms a stable zinc oxide layer that provides additional protection.


5 Benefits of Galvanizing


Choosing galvanized steel for your next project offers a multitude of advantages, including:


  • Enhanced Durability: As we have established, galvanizing significantly extends the lifespan of steel structures. This converts to lower maintenance costs and greater peace of mind.
  • Reduced Life-Cycle Costs: The extended lifespan of galvanized steel means fewer replacement parts and repairs, leading to significant savings over time.
  • Weather Resistance: Galvanization stands strong against numerous environmental conditions, including rain, snow, and even harsh coastal conditions. This makes it ideal for outdoor applications like buildings, fences, and roofing.
  • Aesthetic Appeal: The silvery-grey finish of galvanized steel adds a touch of industrial chic to any project. It can be left as is or painted for further customization.
  • Sustainability: Galvanized steel is recyclable, making it an environmentally friendly choice for most contractors. Moreover, its extended lifespan reduces the need for frequent replacements, further minimising resource consumption.


5 Applications Where Galvanized Steel Shines Through


The versatility of galvanized steel makes it a go-to material for a wide range of applications, including:


  • Construction: From structural beams to roofing sheets, galvanized steel forms the backbone of countless buildings and infrastructure projects.
  • Automotive Industry: Car bodies, chassis, and exhaust systems all benefit from the corrosion protection of galvanizing.
  • Agriculture: Fences, gates, and farming equipment made with galvanized steel withstand the harsh realities of farm life.
  • Marine Industry: Boats, docks, and offshore structures rely on the corrosion resistance of galvanizing to navigate the salty seas.
  • Consumer Goods: From nails and screws to bolts and nuts and anything outdoors, galvanized steel adds longevity and resilience to everyday items in your home or business.


Why Arm Yourself with Armco?


The age-old, traditional process of galvanization is most successful using the hot-dip galvanizing method. This process, if correctly done by trained professionals, involves dipping steel into a molten zinc bath, creating a thick and durable coating, ideal for heavy-duty construction and other applications.


At Armco Superlite, we are listed in accordance with the BSI ISO 9001: 2015 quality management system, which ensures the quality of all our products and services produced by us, which offers you absolute peace of mind. Additionally, we hold the SATAS mark for hot-dipped galvanizing and all galvanized products produced by us at our premises are in accordance with the SANS 121 / ISO 1461 specifications.


Our two galvanizing stations, located at Isando and Randfontein, carry capacities from light to medium structural steel of up to 6m in length to heavy structural steel with lengths of up to 13m, with an average monthly output of close to 3000 tons combined. So, if you need galvanised steel products for your next project, arm yourself with Armco. Consult with us for your superior-quality galvanised steel.
