"In 2018, JMJDWX Steel decided to conduct an important investment to invest and build a galvanized board rolling factory. The project accounts for 25% of our company's overall investment portfolio, showing its importance in the company's strategy. Our company can master more supply chain links, improve product quality and competitiveness, and reduce costs.
We have established a cooperative relationship with some well -known equipment suppliers to ensure that high -quality equipment is obtained. At the same time, we have formed a professional project team responsible for the supervision and management of factory construction. Ensure the normal operation of the production line and meet the expected production capacity and product quality requirements.
We have implemented strict quality control measures, including raw material inspection, production process monitoring, and quality testing of final products. We have also established a comprehensive quality management system to ensure that products meet national and industry standards."
Galvanizing is the process of coating a metal surface with a layer of zinc to improve its corrosion resistance. Zinc is a metal with strong corrosion resistance. Therefore, through galvanizing treatment, the service life of iron, steel and other base materials can be significantly extended, especially in harsh environments, such as moisture, salt spray and other conditions.
Generally speaking, galvanizing is a very effective and economical metal anti-corrosion process and is widely used in modern industry.
At JMJDWX STEEL, we offer the following Galvanized Steel product options:
- Galvanized Steel Sheet
- Galvanized Steel Coil
- PPGI
- GI Roofing Steel Sheet
JMJDWX STEEL is your trusted supplier and exporter of premium industrial steel and metal products. Contact us to discuss your metal needs.
Galvanizing is the process of coating a metal surface with a layer of zinc to improve its corrosion resistance. Zinc is a metal with strong corrosion resistance. Therefore, through galvanizing treatment, the service life of iron, steel and other base materials can be significantly extended, especially in harsh environments, such as moisture, salt spray and other conditions.
The main methods of galvanizing:
Hot-Dip Galvanizing
Hot dip galvanizing is the most common galvanizing method. The process is to heat the steel workpiece to a certain temperature and then immerse it in liquid zinc to cause a chemical reaction between the zinc and the steel surface to form a zinc-iron alloy layer, which is then cooled to form a uniform galvanized layer.
Advantages: The coating is thick, has strong adhesion, and can provide long-term anti-corrosion protection.
Application: Widely used in manufacturing steel structures, auto parts, building materials, wire mesh, etc.
Electrogalvanizing
Electrogalvanizing is the reduction of zinc ions to the surface of steel through electrolysis to form a thin and uniform galvanized layer. Electro-galvanizing has a thin layer of zinc and is generally not as corrosion-resistant as hot-dip galvanizing, but its surface is smooth and suitable for some applications that require a higher quality appearance.
Advantages: The coating is uniform and bright, suitable for products that require a finer appearance.
Application: Commonly used in the manufacture of home appliance casings, light steel, electronic components, etc.
Zinc Spraying
Spray galvanizing is to spray zinc particles onto the surface of the workpiece through a spray gun to form a zinc layer. This method is often used on large structures or older pieces that need repair.
Advantages: Suitable for large-scale structures and on-site processing.
Application: Large steel structures, bridges, etc.
Mechanical Galvanizing
The zinc is adhered to the surface of the workpiece under the action of friction and impact between zinc powder and the workpiece, forming a galvanized layer. This process does not require an electric current or a liquid medium.
Advantages: Able to provide a uniform and dense zinc coating.
Application: Commonly used for anti-corrosion treatment of small parts, such as bolts, nuts, etc.
Advantages of galvanizing:
Improved corrosion resistance: The zinc layer can effectively prevent oxygen and moisture from coming into contact with the substrate (usually steel), reducing the occurrence of rust and corrosion.
Extended service life: Through galvanizing treatment, the service life of metal materials can be significantly extended, especially in harsh environments (such as moisture, salt spray, etc.).
Resistance to mechanical damage: The zinc layer provides certain protection to the substrate to avoid scratches and damage during transportation and use.
Economical: Galvanizing is a relatively low-cost anti-corrosion treatment method and is suitable for large-scale production and application.
Aesthetics: The galvanized surface is smooth, flat, uniform, and has a certain luster. It is often used in situations where a neat appearance is required.
Applications of galvanizing:
Construction Industry: Galvanized steel is used in building structures, roofs, curtain walls, railings, etc.
Transportation: Galvanized steel sheets are widely used in parts of cars, trucks, trains, ships, etc.
Home appliance industry: Galvanized steel sheets for the casings of various home appliances (such as refrigerators, washing machines, etc.).
Electric power industry: Steel used for power towers and transmission lines.
Pipeline engineering: Galvanized pipes are used in water, gas and other fields and have good corrosion resistance.
Agricultural products: Such as galvanized wire, galvanized mesh, etc., which are widely used in agriculture and breeding industries.
Generally speaking, galvanizing is a very effective and economical metal anti-corrosion process and is widely used in modern industry.
