Galvanized steel plank is an alloy material coated with a layer of zinc on the surface of the steel plate. Due to its excellent corrosion resistance, high strength, and good processability, it is widely used in multiple fields. Galvanized steel plank and ordinary steel plate have significant differences in multiple aspects. The following is a detailed explanation of the differences between the two.

The Material and Composition of Galvanized Steel Plank  

Galvanized steel plank: It is a layer of zinc coated on the surface of a regular steel plate through hot-dip or electroplating technology. This layer of zinc is tightly bonded to the steel plate substrate, forming an alloy material with corrosion resistance.

Ordinary steel plate: It is a steel plate with carbon as the main alloying element, composed of carbon and other elements such as manganese, silicon, phosphorus, etc. Its carbon content is usually between 0.05% and 0.25%. It is not galvanized, but processed into various shapes.

Production Process of Galvanized Steel Plank   

Galvanized steel plank: The production process includes multiple steps such as surface treatment, hot-dip galvanizing (or electroplating), cooling, and shearing. These processes require strict quality control to ensure good bonding between the zinc layer and the steel plate substrate, as well as uniformity of the zinc layer.

Ordinary steel plate: production is relatively simple, only requiring some basic processing such as cutting, bending, welding, etc. The quality control requirements for its production process are relatively low.

Performance Characteristics of Galvanized Steel Plank  

Galvanized steel plank:

Has good corrosion resistance, can resist the influence of harsh weather and corrosive environment, and extend the service life.

High strength, capable of withstanding significant external impacts.

The surface is smooth, shiny, and has a metallic luster, suitable for occasions with certain requirements for aesthetics.

Ordinary steel plate:

Moderate strength, suitable for some general construction projects.

Good weldability, suitable for various welding processes.

But its corrosion resistance is poor, and it is prone to rusting and corrosion.

Application Areas of Galvanized Steel Plank      

Galvanized steel plank: Due to its excellent corrosion resistance, high strength, and aesthetics, it has a wide range of applications in various fields such as construction, automobile manufacturing, home appliance and furniture manufacturing. Especially in situations where prolonged exposure to harsh environments is required, such as roofs, walls, car bodies, etc.

Ordinary steel plate: Due to its low cost, good weldability, and moderate strength, it is widely used in industries such as construction, shipbuilding, bridges, machinery, automobiles, electricity, and light industry. But in situations where corrosion resistance is required, ordinary steel plates may not be suitable.

Cost and Maintenance of Galvanized Steel Plank       

Galvanized steel plank: Due to the more complex production process and strict quality control requirements, its cost is usually higher than ordinary steel plate. However, due to its excellent corrosion resistance, it can significantly reduce maintenance costs and replacement frequency.

Ordinary steel plate: Low cost, but requires attention to maintenance and upkeep during use to enhance its service life. Especially in humid and corrosive environments, additional anti-corrosion measures need to be taken.

In summary, there are significant differences between galvanized steel plank and ordinary steel plates in terms of material, production process, performance characteristics, application fields, as well as cost and maintenance. When choosing, a balance should be made between specific application requirements and cost-effectiveness.
