Welcome to Heart Grating
One of the most common methods to treat steel is by galvanizing, coating the steel in a layer of protective zinc.
First the steel has its grease removed and is acid cleaned. Then it is dipped into hot zinc that is over 840 degrees Fahrenheit.
By using special high grade zinc it ensures the best quality and the best protection.
