Galvanized steel: properties, applications, prices

Because of its durability and ease of processing, galvanized steel has become one of the most widely used coated steel products on the market.

The zinc on the surface of zinc steel provides protection for the steel, preventing it from corrosion and enhancing its durability. Galvanized steel is used in projects in various industries that require corrosion-resistant products. This article mainly discusses what is galvanized steel, the production process, characteristics, applications, prices, etc. of galvanized steel.

What is galvanized steel

There are two ways to galvanize galvanized steel, hot-dip galvanizing and electro-galvanizing. Each has its own advantages and disadvantages. The choice of galvanized product mainly depends on your application environment and project budget.

Types of zinc spangles on galvanized steel: large zinc spangles, regular zinc spangles, small zinc spangles, zero zinc spangles

Wanzhi Steel Galvanized steel can be coated with a zinc layer of 30-275g/㎡. The thicker the zinc layer, the stronger the corrosion resistance. Different coatings have different corrosion resistance. The following is the recommended coating weight in different corrosive environments:

In addition to galvanizing to protect steel, spraying paint on the surface of galvanized steel can further protect the steel. After painting galvanized steel, not only the corrosion resistance is improved, but the decorative effect is also greatly enhanced.

Galvanized steel performance

• Corrosion resistance: Galvanized steel has excellent corrosion resistance. The zinc layer on the surface of galvanized steel can prevent the steel from being corroded by corrosive media for a long time.
• Weather resistance: Galvanized steel has high weather resistance. Hot-dip galvanized steel can withstand the test of wind and rain and maintain long-term stable performance in harsh climates.
• Decorative: The surface of galvanized steel is smooth and tidy, with high gloss, which can play a certain decorative effect.
• Processing performance: Galvanized steel has good processing performance and can be processed by stamping, shearing, bending, profiling and other processing methods.
• Economic performance: Compared with other anti-corrosion methods (such as stainless steel), the anti-corrosion method of galvanizing has relatively low cost and good economic performance.

Application of galvanized steel

Due to its corrosion resistance and weather resistance, galvanized steel can also maintain long-term stable use in outdoor environments. We can see the use of galvanized steel in various fields, including construction, agriculture, transportation, traffic, home appliances, electricity, etc.

Wanzhi Steel produces galvanized steel products, including galvanized steel sheets, color-coated galvanized steel, galvanized steel pipes and other products. The application range of galvanized steel sheets and color-coated galvanized steel is similar. The following mainly shares the application of galvanized steel sheets and galvanized steel pipes:

Application of galvanized steel sheets

• Construction field: roofs, walls, bridges, fences, guardrails, etc.
• Home appliance field: home appliance shells and internal components, etc.
• Automotive field: car bodies, doors, parts, etc.
• Transportation field: containers, highway enclosures, partitions, etc.
• Furniture field: lampshades, desks, counters, bookshelves, etc.

Application of galvanized steel pipes

• Construction field: used for support, frames, pipelines, etc. of building structures.
• Petroleum field: oil field production, oil pipelines, oil tanks, etc.
• Chemical field: used for transporting chemical media, manufacturing chemical processing equipment, etc.
• Mining industry: coal mine support, mine shaft, gas extraction, etc.

The price of galvanized steel

The price of galvanized steel is affected by factors such as the thickness of the zinc layer, specifications, material, and surface type. Below we share the price information of Mysteel 8.30 Chinese galvanized steel.

Will galvanized steel rust?

Although galvanized steel is protected by a zinc layer, if the zinc layer is damaged, the galvanized steel will rust.

The time it takes for the zinc layer to be damaged is affected by the thickness of the zinc layer and the application environment. Environmental factors affecting corrosion performance include:

• Ambient pH
• Temperature and humidity fluctuations
• Rainwater (especially acid rain)
• Sunlight

Conclusion

Galvanized steel plays an important role in many fields due to its excellent properties such as corrosion resistance, decorativeness, and wear resistance. Although galvanized steel is widely used, there is one thing we need to remind you. Galvanized steel has strong resistance to alkaline environment, but it is not very good for use in acidic environment, and its life will be shortened.

Wanzhi Steel has two galvanized steel production lines with an annual output of more than 600,000 tons of galvanized steel. Our galvanized steel is factory wholesale price. We have sufficient capacity to produce large-volume orders. The more you purchase, the greater the price discount. If you have a project that requires the purchase of galvanized steel, you can contact Wanzhi for details.
