There are significant differences between carbon steel sheets and galvanized sheets in many aspects. Here are their main differences:
1. Material composition and structure
Carbon steel plate:
Definition: Carbon steel plate is an alloy steel plate composed of carbon and iron, with a carbon content between 0.12% and 2.0%. According to the different carbon content, it can be divided into low carbon steel plate, medium carbon steel plate and high carbon steel plate.
Features: Carbon steel plate is an alloy of iron and carbon and does not contain other alloying elements (except carbon controlled within a certain range). Therefore, its hardness is greater than that of pure iron, but it does not have anti-corrosion properties.
Galvanized sheet:
Definition: Galvanized sheet is a metal material that is coated with a zinc layer on the surface of a carbon steel sheet. The galvanized layer can play an anti-corrosion role and extend the service life of the steel plate.
Features: Galvanized sheet adds a layer of zinc to the carbon steel sheet. This zinc layer can effectively prevent the steel sheet from being corroded. The thickness of the galvanized layer is usually above 20 μm. According to the thickness of the galvanized layer, it can be divided into ordinary galvanized sheets, reinforced galvanized sheets and super galvanized sheets.
2. Physical and chemical properties
Carbon steel plate:
Physical properties: Carbon steel plate has high strength and hardness, good wear resistance, and is easy to process, such as milling, turning, drilling, cutting, etc.
Chemical properties: Since it does not contain anti-corrosion elements, carbon steel plates are easily corroded in corrosive environments.
Galvanized sheet:
Physical properties: Galvanized sheets inherit the physical properties of carbon steel sheets, and at the same time have better corrosion resistance due to the zinc layer on their surfaces.
Chemical properties: The galvanized layer can prevent the steel plate from direct contact with corrosive media, thus greatly extending the service life of the steel plate.
3. Application fields
Carbon steel plate:
Main applications: Carbon steel plates are widely used in construction and manufacturing due to their high strength, wear resistance and easy processability, such as steel structures, bridges, ships, automobile manufacturing, etc.
Galvanized sheet:
Main applications: Galvanized sheets are mainly used in situations where anti-corrosion properties are required, such as steel structures, roofs, wall panels, cement precast panels, etc. in the construction industry. In addition, galvanized sheets are also widely used in home appliances, vehicles and ships, container manufacturing and other fields.
4. Cost and Price
Carbon steel plate: Since the production process of carbon steel plate is relatively simple and the cost of raw materials is low, its price is relatively low.
Galvanized sheet: Galvanized sheet adds a galvanizing process to the carbon steel sheet, so its production cost and price are relatively high.
5. Summary
There are significant differences between carbon steel sheets and galvanized sheets in terms of material composition, physical and chemical properties, application fields, and cost and price. When choosing for use, comprehensive consideration should be made based on specific needs and application scenarios. Where high strength, wear resistance and low anti-corrosion performance are required, carbon steel plates can be selected; while where anti-corrosion performance is required, galvanized plates should be selected.
Classification of stainless steel pipes1. Classification by production method:
(1) Seamless tubes - cold drawn tubes, extruded tubes, cold rolled tubes.
(2) Welded pipe:
(a) Classification by process - gas shielded welded pipe, arc welded pipe, resistance welded pipe (high frequency, low frequency).
(b) According to welding seam - straight seam welded pipe, spiral welded pipe.
2. Classification according to cross-sectional shape: (1) circular steel pipe; (2) rectangular pipe.
Spiral steel pipe stacking requirements1. The principle requirement for stacking spiral steel pipes is to stack them according to types and specifications on the premise of ensuring stable stacking and ensuring safety. Different types of materials should be stacked separately to prevent confusion and mutual erosion;
Difference Between Straight Seam Steel Pipe and Spiral Steel Pipe
Advantages of Using Carbon Steel in ConstructionSteel is an alloy metal, which means it’s a combination of several types of elements. In the case of steel, this is a combination of iron, carbon, and trace elements. It has a number of advantages for construction applications due to the fact that it’s fairly inexpensive to manufacture and has a very high tensile strength.
What determines the type of steel is the ratio of elements used to produce it, and it’s the magic formula of the carbon steel alloy created that makes it preferred for many projects. While there are thousands of different types of steel, these types are generally bucketed into four categories: carbon steel, alloy steel, stainless steel, and tool steel.- Anti-corrosion steel pipe classificationPN8710 anti-corrosion
When there are many types of corrosive media in steel pipes, such as acids, alkalis, salts, oxidants and water vapor, the coating must be chemically inert and resistant to acid, alkali and salt corrosion. The coating film should have a dense structure, good waterproof permeability and strong adhesion. , tough and plump. In this case, IPN8710 anti-corrosion is suitable. 
Global crude steel production fell 4.3% year-on-year in MarchOn April 23, the World Steel Association (WSA) released global crude steel production data for March. In March, crude steel output in the world's 71 countries and regions included in the statistics was 161.2 million tons, a year-on-year decrease of 4.3%. In the first quarter of this year, crude steel output in the world's 71 countries and regions included in the statistics was 469 million tons, a year-on-year increase of 0.5%.
