Minimium Spangle 0.12mm-6.0mm Thickness Sheet Metal Galvalume Steel Coil

Hot-dip galvanizing is generally used for steel strip or wire (stranded wire). The steel surface is covered with zinc layer to prevent the erosion of the atmosphere, and to ensure the service life of the substrate. Moreover, zinc is more active than iron, and can also sacrifice zinc layer to protect the steel matrix in the case of corrosion. Aluminized zinc has stronger protective effect and better corrosion resistance than galvanized products. The whole structure consists of aluminum, iron, silicon and zinc, forming a dense tetrad crystal, which forms a barrier on the steel plate, thus effectively preventing corrosion factors from penetrating. Corrosion resistance comes from aluminum's barrier layer protection function, and zinc's sacrificial protection function. Aluminum forms an insoluble oxide layer that acts as a barrier when zinc sacrificial protects the cut edges, scratches and scratches of the coating. As for the difference in use, if galvanized products can not prevent corrosion, you can further choose aluminum zinc plating.

Aluminized zinc color coating plate is a new material produced by high-end application in China in recent years, often referred to as CCLI. It is made of aluminized zinc plate (55% aluminum, 43% zinc and 1.6% silicon) which is more corrosion resistant than zinc plating, after surface degreasing, phosphating and complex salt treatment, coated with organic coating and baked.
Aluminized zinc color coated plate (AZ150,G345A,PVDF) is very suitable for construction or other facilities in extreme environment, very corrosion and weather resistance, and this steel plate can guarantee more than 20 years of service life.
Ordinary color steel coil is a kind of composite material, also called color coating steel plate is made of strip steel in the production line after continuous surface degreasing, phosphating and other chemical transfer coating treatment, coated with organic coating by baking products. Both steel and organic materials have a little bit. Not only the mechanical strength of steel plate and easy molding performance, but also the good decorative organic materials, corrosion resistance.

Jiangsu Irunt Steel Group Co., Ltd. is located in Wuxi City , Jiangsu Province, China, which is the largest steel production base. After 30 years of efforts, it has grown from a family factory to a group company.

The group company mainly produces and sells a series of steel products such as steel pipe, steel coil, steel plate, copper pipe, copper plate, copper strip, aluminum pipe, aluminum plate, galvanized steel pipe, galvanized coil, galvanized plate and so on.The group company has established five platforms, including three production plants and two processing plants. At present, it is still expanding its production line, basically forming a development model of integration of production, processing and sales.

Our annual production capacity of various specifications is about 1 million metric tons. In addition to being a supplier of our series of products, the group company is also committed to expanding its commitment to customers by strengthening services and adding new facilities. A dedicated team is responsible for providing technical support, recommending the correct use of steel, and assisting customers to give full play to their products.

Over the years, we have opened up new markets in Africa, Southeast Asia, the Middle East and America. Our best service and excellent quality have led long-term partners in many countries and established continuous business relations with all customers. Our principle is "service first, sales second". Most of the time, we have comprehensive inspection and procurement to control the quality of finished products. We will have a professional inspection team to test each delivery of products.

Since its establishment, in line with the mission of "contributing high-quality products and services to the world" and the core values of "customer first, excellence, coexistence and win-win", we ensure that we can deeply cooperate with all our friends in the field of iron and steel, and win more affirmation and praise from the market and customers with its high-quality products, perfect product team and thoughtful service, I believe tomorrow will be better!
