Ecuador is a mature market where Wanzhi Steel Group has been operating for many years, and our business managers have established friendly cooperative relations with Ecuadorian customers. On February 1, 2023, the Ecuadorian customer purchased 200 tons of alu-zinc coils from Wanzhi Steel. After receiving the products, the customer was delighted with the quality of the products. On April 14, 2023, the customer contacted our business manager and wanted to repurchase 200 tons of galvalume coils, and expressed concern about the quality of the coil. After negotiation, the sales manager sent the sample of galvalume steel coils to the customer. The customer is delighted with our sample. On June 14, the customer signed a contract with us to purchase 200 tons of alu-zinc coils from Wanzhi again. Now the production has been production completion and sent to Ecuador.
The surface of the aluminized zinc coil is characterized by smooth, flat, and gorgeous star flowers, and the primary color is silver-white. The composition of the coating is 55% aluminum, 43.4% zinc, and 1.6% silicon by weight ratio, respectively. The production process of aluminum-zinc plating is similar to that of galvanized steel plates and aluminum-plated plates, which is a continuous melting plating process.
When the aluminum-plated zinc of 55% aluminum-zinc alloy coating and the galvanized steel plate of the same thickness are exposed to the same environment, the aluminum-plated zinc has better corrosion resistance. In addition to its good corrosion resistance, color-coated aluminum zinc has excellent adhesion and flexibility.
The thermal reflectivity of aluminized zinc steel coil is very high, which is twice that of galvanized steel plate, and people often use it as a thermal insulation material.
Aluminum-zinc alloy steel plate has a good heat resistance and can withstand the high temperature of more than 300 degrees Celsius, and the resistance to high-temperature oxidation of aluminum-zinc steel coil is very similar, often aluminum-zinc steel coil is used in chimney tubes, ovens, illuminators, and daylight lampshades.
Because the density of 55%AL-Zn is smaller than that of Zn, the area of the aluminized zinc steel plate is more than 3% larger than that of the galvanized steel plate under the same weight and the same thickness of the gold plating layer.
There is excellent adhesion between aluminum-zinc steel coil and paint, and it can be painted without pretreatment and weathering treatment. The coating adhesion of aluminum-zinc coated steel coil gold coating is excellent, and it can be directly coated on advertising boards and general boards.
1. Use aluminum-plated zinc steel plate with caution under the conditions of an alkaline medium (strong alkaline introduction and aluminum medium are prone to chemical reaction)
2. The roof of the aluminum-plated zinc steel plate building should have a certain slope, which is conducive to drainage and avoiding worsening corrosion (the slope is not less than 10 degrees).
3. Avoid direct contact with warm cement and wet wood, lead, copper, and graphite.
4. Cutting plates should be used as much as possible to avoid cutting on the site. Expose the incision to air.
5. Processing and stacking should be prevented by moisture and high temperature caused by the fingerprint-resistant surface film black.
6. Aluminum-plated zinc steel plate used for foaming bonding should be tested in small batches when it is used for the first time to prevent poor bonding performance.
7. It is not recommended to use alcohol-based solvents to wipe and clean the surface. If necessary, please conduct a sample test first to avoid damage to the surface coating.
As we all know, Wanzhi Group Co., Ltd. has achieved the world’s leading level in producing galvalume coil. Our galvalume steel coils have been sold to more than 100 countries and regions in the world, such as the Philippines, Turkey, Libya, Lithuania, Iran, and so on. The main reason why our galvalume steel coils are popular, in addition to the professional business managers, is the quality of the alu-zinc coils. We have purchased foreign imported equipment to produce alu-zinc coil. We also have professional quality testing tools for quality testing. Thus, customers are highly assured of the quality of our products. In addition to galvalume steel coils, we can also produce galvanized coils and color-coated steel coils. Please feel free to contact us for the latest quotation.
Finally, thanks to the trust of Ecuadorian customers, Wanzhi Group will make more significant efforts to provide customers with high-quality products. Ecuadorian customers will soon receive 200 tons of aluminized zinc coils. Please feel free to contact us if you have any quality problems. We have a professional after-sales manager at your service. If you are buying steel coil from China for the first time, you are welcome to visit our factory at any time, our professional steel coil engineers will receive you!
