What are the pros and cons of galvanised steel?
Being tough and durable, it is resistant to scratches and everyday damage. Any damage tends to occur through mishandling and untreated long-term wear and tear. Due to its smooth surface, should the galvanised steel sheet incur any damage, the integrity of the protection is compromised, making it prone to rusting
What are the disadvantages of galvanized steel?
As with any kind of steel finishing, galvanized steel has its cons, which include:
There can be a high cost associated with galvanization, especially in large-scale projects. ...
Although resistant to red rust, galvanized steel can develop white rust over time if exposed to moisture.
