What is galvanised steel coil sheet?

Galvanised steel’s defining attribute is its layer of zinc coating, which forms a protective layer against the combination of moisture and oxygen that can otherwise cause rust to form on the underlying metal. Rust slowly but surely eats away at steel, reducing its integrity and ultimately creating safety issues whether the steel is used in a purely functional application or is part of an impressive, customised facade or other design element.

Galvanisation takes regular steel or another metal, like iron, and adds a zinc coating. This process, which can be completed in a few different ways, helps increase versatility and allows for many different types of steel and iron to be easily galvanized. The hot-dipping galvanisation process provides a strong, relatively thick coating for large pieces of steel using molten zinc. Thermal diffusion galvanizing, meanwhile, is common for smaller pieces of metal, especially those that have a more complex design. Both hot dip galvanisation and thermal diffusion galvanising have powerful applications.

Is galvanized steel water proof?

Galvanized steel can withstand water exposure, but not saltwater exposure and should not be used in buildings near saltwater. Galvanized steel is a coating over plain steel. If that coating is compromised, the steel underneath will rust. Stainless steel is resistant to corrosion due to the added chromium
