Galvanized Steel Advantages
Since its sacrificial zinc layer protects from many different types of environmental conditions, galvanized steel offers many unique benefits, these include
Rust Resistance: Iron in steel is incredibly prone to rust, but zinc acts as a protective buffer between moisture, oxygen, and steel.
Easy Inspection: It's fairly simple to tell how strong a galvanized coating is, just by looking at it. Quick stress tests that can tell you how thick the zinc is.
Sacrificial Anode: This ensures that any damaged steel is protected by the surrounding zinc coating. It doesn't matter if the steel section is completely exposed; the zinc will still corrode first.
Longer Life: With galvanization, a piece of industrial steel is expected to last more than 50 years in average environments and can last over 20 years with severe water exposure. No maintenance required.

Methods of Galvanizing Steel
There are four ways in which steel can be galvanized, each affecting the type of layer formed and the final application. The four methods are described below
Galvannealing is the combination of hot-dip galvanizing and annealing processes to produce a specialized coating on steel sheets. The finished product is a zinc-iron alloy product, with a dull matte surface finish that is ideally suited for paint adhesion. This process works by hot-dipping the base metal, and then heating it in an annealing oven at a temperature of roughly 565 ºC to induce alloying between the steel and molten zinc coating. Examples of galvannealing include: welding operations, marine applications, and any high-tensile stress applications.
Hot-dip galvanizing is a form of zinc coating applied to steel sheets (or manufactured steel items). This occurs by passing the steel objects through a bath of molten zinc and then cooling them. The zinc bonds to the iron within the steel. Hot-dip galvanizing works by forming a protective layer on either side of the metal to protect the finished product from corrosion. Galvanized steel does not require any secondary or additional coating or painting. Examples of hot-dip galvanizing include: industrial flooring, motorway guardrails, brackets, and fixings.
Electrogalvanization is a process in which steel is galvanized with a zinc coating using electroplating. Steel is submerged in a zinc salt solution and an electrical current is applied to create electrogalvanized steel. The current creates a reaction between the zinc salt and the surface of the steel, leaving behind a thin layer of zinc. This zinc laver is much thinner than the hot dipping method. Electrogalvanized steel is used in: acoustic ceiling tiles, door frames, and switchboards.
The pre-galvanizing process, also referred to as mill galvanization, is performed at the very initial stages of production on metals which are likely to have a limited number of processes after pre-galvanization. This is because carrying out any process on galvanized steel will result in the exposure of bare metal to the atmosphere increasing the risk of oxidation. Components that are pre-galvanized are usually steel plates and bars. This method enables galvanizing to be done quickly and efficiently on a larger scale than is possible with traditional hot-dipping. This process works by rolling the sheet metal (or other shaped steel stock) in a cleaning agent to prepare the material to be passed through the molten zinc, which is then rapidly recoiled. Pre-galvanizing is primarily used for materials that already have a specific shape before being cut.

Attentions in Transportation and Storage
1
Galvanized Steel Coils should be stored in neat and tidy environment to avoid possible corrosioncaused by all kinds of corrasive medium.
2
The ground for storage should be flat, without hard object, and with sufficient loading-bearing capacity.
3
Storage environment should be dry and ventilated. Avoiding storing outdoors or with dew or with wide temp difference.
4
Coil could not be dragged lest the burr caused by slicing will scratch the coil surface underneath.Coil should be handled with care, without hitting any hard object
