Types of Galvanized Steel Coil
The galvanized steel coils produced by our company mainly include the following types:
Hot Dipped Galvanized Coil
Hot Dipped Galvanized Coil is a steel product that has been specially processed. It forms a uniform and dense zinc alloy coating on the surface of the steel by immersing the cleaned steel products in molten zinc liquid and using the chemical reaction and atomic diffusion between iron and zinc.
Cold Rolled Galvanized Steel Coil
The cold rolled galvanized steel coil is made of cold-rolled steel strip as the substrate through continuous hot-dip galvanizing process. The product has the characteristics of strong corrosion resistance, good surface quality, conducive to deep processing, economical and practical.
Advantages of Galvanized Steel Coil
Super protection
Galvanized steel coil can prevent corrosion on the surface of the steel plate and prolong its usable time. Every inch of galvanized steel coil is protected, even the sharp edges and hard-to-reach cracks.
Low maintenance
The steel that lacks protective coating needs more maintenance to keep the appearance and structure of the product safe.
Economically
The initial choice of galvanized steel coil may seem more expensive, but in the long run, it is a huge investment. In addition, galvanizing is actually cheaper than many other protective steel coatings.
Long durability
The life expectancy of the galvanized steel coating can reach 50 years, and it can withstand the exposure of cities and coastal areas.
Applications of Galvanized Steel Coil
1. Application of galvanized steel coil in the production of steel pipes and boxes
1 in 5 unmissable applications of galvanized steel coils is the production of steel pipes and steel boxes. The galvanized steel coil is the primary raw material for producing steel pipes and box steel. Steel boxes and steel products produced by galvanized steel coils have outstanding advantages, such as high durability, a long service life, resistance to harsh environments, and less prone to rust or corrosion.
2. Application of galvanized steel coil in construction
Steel plays a very important role in the construction of structures. Galvanized steel coil has sustainable structures used as partitions, ceiling frames, and frame supports for houses and public buildings such as hospitals, schools, et cetera. Thanks to outstanding advantages such as corrosion resistance and anti-rust, galvanized steel coils are also the primary source of raw materials for producing ventilation pipes, purlins, deck floors, et cetera.
3. Application of galvanized steel coil in the fabrication industry
It can be said that one of the 5 essential applications of galvanized steel coil is the manufacturing industry. A series of manufacturing industries that play an essential role in human life involves galvanized steel coils, such as electronics manufacturing, machinery manufacturing, printing, fuel extraction, et cetera.
4. Household industry
It can be said that one of the 5 essential applications of galvanized steel coil is the application in the household industry. The household appliances industry affects people's daily lives innumerable. The galvanized steel coil is widely applied in producing household appliances such as televisions, phones, and refrigerators to simple kitchen appliances.
5. Application of galvanized steel coil in shipbuilding
Like in construction, galvanized steel coils are also widely used in shipbuilding. Galvanized steel coil specialized for constructing ships in the marine industry with high durability and resistance to sea salt corrosion. It mainly manufactures oil rigs, hulls, and repair ships. Galvanized steel coils can also manufacture heavy-duty ships carrying bulk cargo.
Galvanizing Method of Galvanized Steel Coil
Hot-dipped galvanisation
In this process, steel is dipped into molten zinc. This is the fundamental process of galvanising.
01
Galvanealing
It is a combination of galvanising and annealing. The process involves hot-dipping in the molten zinc followed by instantaneous annealing. This process creates specialized coating on steel.
02
Pre-galvanising
It is same as hot-dipped galvanising method. However, this activity is performed in the steel mill itself. Here, steel is passed through the molten zinc and recoiled immediately. This method offers uniformity in coating and rapid galvanisation is achieved.
03
Electrogalvanising
This is a unique method where in steel is not dipped into molten zinc. Instead, it is an electrolyte solution that coats steel with zinc using electric current.
04
Galvanising advanced high-strength steel
This method also involves dipping method in the molten zinc. However, what differentiates this method from others is the additional chemical treatment.
05
Storage Requirements for Galvanized Steel Coils
Indoor Storage:
Whenever possible, store galvanized steel coils indoors to protect them from environmental elements. This prevents exposure to moisture, which can lead to rust and compromise the zinc coating.
Dry Environment:
Maintain a dry storage environment to prevent condensation. Moisture can accelerate corrosion, adversely affecting the galvanized surface. Consider using dehumidifiers in storage areas.
Ventilation:
Adequate ventilation is essential to prevent the accumulation of humidity. Well-ventilated storage spaces contribute to a stable environment and minimize the risk of corrosion.
