What is galvanizing?

Galvanizing is a manufacturing process that involves applying a zinc coating to steel to prevent it from rusting. The galvanized coating acts as a protection for the base metal. It does this by acting as a barrier to various corrosive elements. Thus, it offers a sacrificial nature that can provide high quality and long lasting steel products.

Galvanized steel is one of the popular grades of steel. This is due to its increased strength, extended durability and formability. Corrosion resistant properties make it significantly more useful.

Its versatility ensures that it has a wide range of applications. There are many more advantages of using galvanized steel.

The galvanized coating prevents corrosive substances (e.g. acids) from reaching the base metal.

When the coating is scratched, zinc is more easily sacrificed to the anode than base metals. Therefore, it provides complete protection against rust.

Zinc corrodes faster than base metals. This activity is a good way to protect base metals. Since the objective is to allow the zinc to rust before the metal for adequate protection, chromates can be added.

Product details

According to the European Standard EN 10346:2015, the dimensions of hot-dip galvanized zinc spangle can be divided into normal spangle and minimized spangle.

The normal spangle is the size and shape of the zinc grains formed after normal solidification of the zinc solution, while the spangle without zinc (also known as the minimized spangle) is the size and shape of the zinc grains obtained by special control of the zinc solidification process. If the user wishes to specify the size of the zinc flower, this should be negotiated at the time of ordering.

There are many factors that affect the size of the zinc flower. When the composition of the zinc liquid has the conditions for the formation of the zinc flower, the following factors have an effect on the size of the zinc flower:

(1) Raw material: the thicker the raw steel plate, the smaller the surface roughness, the larger the zinc flower.

(2) Cooling speed: the faster the cooling speed, the shorter the crystal growth time, the smaller the zinc flower.

(3 ) The number of nuclei: the size of the zinc flower and the number of zinc flower nuclei have a close relationship. When the steel base surface roughness or poor surface cleanliness, the zinc flower is relatively small. Zinc grain formation on the steel base, the more nuclei, the smaller the zinc flower, small zinc flower production process spray water mist method makes use of this principle.

(4) Other factors (production environment, etc.)

Galvanized steel coil is used in a wide range of applications and has the advantage of a long corrosion protection period. It is mainly used as a building and substrate for household appliances, office panels, roofing panels, automotive panels, and pre-painted steel coils.

Automotive Steel Sheet

To use automotive steel sheet must first be stamped and formed, the steel sheet is stamped into parts of the desired shape and size.

Spot welding is widely used in manufacturing, especially in the automotive industry, as an important welding method for joining thin plates.

Galvanized Roof Sheet

The performance requirements of galvanized roofing sheets mainly include the mechanical properties of the material (tensile strength, yield strength, elongation), coating properties (coating type, coating thickness and coating adhesion)

Home Appliance Office Board

Including air conditioners, washing machines, refrigerators, copiers, etc. Household galvanized sheets are mainly used for general forming applications and stamping.

Substrate

Another use for galvanized steel coils is as a substrate for pre-painted steel coils. Pre-painted steel coils are more durable than galvanized coils as they have a polyethylene coating.
