What is Hot Dip Galvanising?

IN BRIEF
Hot dip galvanising is a crucial process for coating steel with zinc to prevent corrosion, offering long-term durability and rust resistance. It’s an essential feature in industrial sheds, commercial steel buildings, and warehouse projects exposed to harsh elements.
What is Hot Dipped Galvanized Steel?
Hot dip galvanising is the process of coating iron, steel, or other ferrous materials with a layer of zinc. This is achieved by cleaning the material to remove any scale or loose material, immersing it in a pickling bath of hydrochloric acid, and finally passing it through molten zinc at a temperature exceeding 400 degrees Celsius.

This process causes the metal to react with carbon dioxide, forming zinc carbonate. This strong compound provides effective protection against corrosion, making galvanised steel ideal for use in industrial steel construction services.
Why Hot Dip Galvanising is Essential for Industrial Steel Builders
Hot dip galvanising is a reliable solution to protect steel and other ferrous metals from rust. The zinc coating seals the material, adding an extra layer of protection. Additionally, the coating enhances abrasion resistance, making the material more durable. Even if minor scratches occur, the surrounding galvanised layer continues to provide corrosion protection due to the cathodic action of the zinc.
For industrial shed builders and those involved in warehouse projects, opting for hot dip galvanised steel ensures that the steel components remain rust-free and functional for a long time, even in challenging environments.
Rust Protection for Every Nook and Cranny
An essential benefit of hot dip galvanising is its ability to coat every inch of the steel, including hard-to-reach areas such as bracing, purlins, struts, and irregularly shaped components. This comprehensive coverage is critical because corrosion often occurs in internal areas where condensation can accumulate, such as within hollow structures. These areas are more susceptible to moisture retention, which accelerates rust formation.

With hot dip galvanising, every interior and exterior surface is protected, ensuring the steel remains robust and free from corrosion over time.
Benefits of Hot Dip Galvanised Steel in Industrial and Commercial Steel Structures
- Exceptional corrosion resistance: Hot dip galvanising offers long-lasting protection for industrial sheds and other industrial buildings exposed to the elements.
- Increased abrasion resistance: The galvanising process creates a more durable material that is tougher than the original steel.
- Cost-effective solution: Galvanising reduces the need for ongoing maintenance, making it a cost-efficient choice for steel construction services.
- Predictable performance: Galvanised steel performs reliably over time, making it ideal for long-term warehouse projects.
- Mechanical damage resistance: Even minor scratches won’t compromise the performance of the steel, thanks to the protective properties of the zinc coating.
- UV radiation resistance: Unlike many painted finishes, galvanised steel is not affected by UV radiation, maintaining its structural integrity under the sun.
- A unique aesthetic: Over time, galvanised steel takes on a distinctive matte grey patina, which can add an appealing architectural feature to your building.
