Answer

The zinc dip prevents the steel from rusting. As the zinc is more reactive than the Iron in the steel, it reacts with the water and air first and in doing so protects the steel for a time. This protection is partly electrical (like a battery) so even if there are holes in the zinc coating the exposed steel will still not rust.

Answer

Zinc is often applied to steel to increase its resistance to corrosion. The process is called galvanization. We find that steel "steps" screwed into wooden power poles are galvanized, as are steel guardrails on motorways (just to name a pair of applications).

Zinc is used in galvanizing because zinc can be made to stick to iron and does not rust. In addition, when you cut it, the zinc will cover the iron at the point where it is cut. The whole process makes sheet iron last much longer.

Things made of steel and iron are galvanized to protect them from rusting.

In the galvanizing process, an object made of steel or iron (or sometimes other metals) is put through a bath of molten zinc, which coats it. The zinc is rather reactive and its surface reacts with oxygen to form zinc oxide. The zinc oxide, unlike rust, does not flake off, but remains in place. And the zinc oxide, in turn, reacts with atmospheric carbon dioxide to form zinc carbonate, which also remains in place. Zinc carbonate is a pretty good protective layer.

Zinc is used as a sacrificial anode when it coats iron or steel to prevent oxidation of the iron or steel.

What does galvanise mean?

"Galvanized" is an adjective used to describe steel which has been coated with zinc metal. Galvanized steel is quite well protected from corrosion by the zinc coating which provides the steel with both physical and chemical protection. There are currently 3 processes which are used for galvanizing steel: (1) hot dip galvanizing, (2) electrogalvanizing, and (3) thermal diffusion galvanizing.


What is the melting point of galvanized steel?

Typically, galvanizing refers to hot-dip galvanizingwhich is process of submerging steel parts into molten zinc. Zinc will melt at 787.15 °F. In a galvanizing environment, most of the smoke is flux burn-off from the preparation process. Depending on the specific galvanizing company, zinc is generally maintained between 820 - 860 °F.Hot-dip Galvanizing Zinc Temperature Range820 - 860 °F (449 - 460 °C)Zinc Melting Point787.15 °F (419.53 °C)


What is type of process is galvanizing?

Galvanizing is the process of dipping steel or iron into a bath of molten zinc. The zinc coating served as a corrosion prohibitor, and was applied to structural parts, sheeting, pipe, various containers, and hardware.


What are useful materials thet can be extracted from zinc?

Zinc is an element. There is nothing but zinc in zinc so nothing can be extracted from it. Zinc can be combined with other elements to make useful products. It is used in rustproofing (galvanizing) and in skin ointments (zinc oxide). Avery tiny amount of zinc is necessary in human diet.
