1. Brief Introduction of Corrugated Galvanized Steel Sheets
Galvanized corrugated sheet refers to a steel sheet that is galvanized on the surface. Galvanizing is a cost-effective method of corrosion protection that is often used. This process uses about half of the world's zinc production. Galvanized corrugated sheet is designed to prevent corrosion on the surface of the steel sheet and prolong its service life. The surface of the steel plate is coated with a layer of metallic zinc.
2. Classification of Corrugated Galvanized Steel Sheets
According to the production and processing method, corrugated galvanized steel sheets can be divided into the following categories:
Galvanized Corrugated Board: The steel sheet is dipped in a bath of molten zinc, thereby adhering the steel sheet with the zinc layer to the surface. The continuous galvanizing process is mainly adopted, where the coiled steel plate is continuously immersed in a galvanizing tank and is made into a galvanized steel plate together with molten zinc.
Alloy Galvanized Corrugated Board: This kind of steel plate is also made by hot dipping, but immediately after being discharged from the tank, it is heated to about 500°C to form an alloy film of zinc and iron. The corrugated galvanized steel sheet has good paint adhesion and weldability.
Electro-Galvanized Corrugated Board: Galvanized steel sheets produced by electroplating have good machinability. However, the coating is thinner and its corrosion resistance is not as good as that of hot-dip galvanized panels.
Single-Sided and Double-Sided Galvanized Corrugated Sheets: Single-sided galvanized steel sheet is a product that is galvanized on only one side. In terms of welding, painting, anti-rust treatment, processing, etc., it has better adaptability than double-sided galvanized panels. To overcome the disadvantage of not being galvanized on one side, another corrugated galvanized steel sheet is coated with a thin layer of zinc on the other side, that is, double-sided differential corrugated galvanized steel sheet.
Alloy and Composite Galvanized Corrugated Board: It is a steel plate made of zinc and other metals, such as lead and zinc alloys, or even composite coatings. This kind of steel plate not only has excellent anti-rust performance but also has good coating performance.
In addition to the above five types, there are also colored galvanized corrugated sheets, printed coated galvanized steel sheets, PVC laminated galvanized steel sheets, etc. But the most commonly used is still hot-dip galvanized steel.
3. Function of Corrugated Galvanized Steel Sheets
After the corrugated galvanized steel sheet is processed, not only the quality is very good, but it also has many other characteristics during use:
Strong Corrosion Resistance: The primary function of the surface treatment is to prevent the steel plate from being corroded. Due to strong corrosion, it will have a significant impact on the service life of the product. Therefore, after the surface is coated with a layer of metal zinc, the product life can be extended.
Safety Protection: The treated corrugated galvanized steel sheet can indeed play a very good role in safety protection. The surface coated with metal zinc has many characteristics during actual use, preventing surface damage and providing better safety protection.
The mechanical properties of corrugated galvanized steel sheets in actual use are very significant. These sheets have strong tensile properties, high tensile strength, and shrinkage, making them very popular in the market.
4. Brief Introduction of Shandong Sino Steel Co., Ltd.
Since its establishment in 2002, Shandong Sino Steel Co., Ltd., founded in the beautiful port city of Qingdao, has focused on the production, processing, sales, and export of coated coils, non-ferrous metal coils, and other products. The company is committed to being a building material supply chain integration service provider.
As of the first half of 2022, the group has sold products to more than 150 countries, serving over 3,000 customers, with more than 1,000 having long-term partnerships. Shandong Sino Steel Co., Ltd. has established a complete industrial chain of procurement, production, processing, transportation, warehouse management, and independent marketing network.
As the foreign trade window of China's steel industry, the group has extensive exchanges and friendly cooperation with domestic and foreign manufacturers based on equality, mutual benefit, and win-win cooperation. This greatly supports the healthy and rapid development of China's steel industry. The group's development direction is to build a global one-stop procurement center for building materials products, continuously expanding its business areas.
In the next strategic plan, the group will continue to optimize and innovate, speeding up the layout of more overseas warehouses, factories, and companies. Adhering to the vision of "building an internationally competitive supply chain integration service provider" and the mission of "focusing on value-based services and making choices simple" for customers, the group aims to develop comprehensively and steadily.
