Hot Dipped Slit Galvanized Sheet Coil Coil SGCC Steel With Spangle Gi Coil

Hot Dipped Slit Galvanized Mild Steel Coil with Spangle Gi Coil SGCC Steel

Definition of galvanized sheet coil
Is rolling under recrystallization, but generally understood as the use of rolling materials at room temperature. Cold aluminum rolling is divided into plate rolling and foil rolling. The thickness of 0.15~ above is called plate, 0.15~ below is called foil, Europe and The United States mostly use 3~6 continuous rolling mills as cold rolling equipment.
The production process
Due to no heating in the production process, there is no hot rolling often occur pitting and oxide iron defects, good surface quality, high finish. Moreover, the size precision of cold-rolled products is high, and the properties and structure of cold-rolled products can meet some special requirements, such as electromagnetic properties, deep drawing properties, etc.
Three, galvanized roll material.
Galvanized coil due to different processing methods in the coating and plating process, the surface state is also different, such as ordinary zinc coil, fine zinc coil, flat zinc coil, zinc free coil and phosphating surface. Galvanized coil should have a good appearance, shall not be harmful to the use of the product defects, such as no plating, holes, cracks and scum, over plating thickness, abrasion, chromic acid dirt, white rust, etc..
According to the production and processing methods can be divided into the following categories:
A) Hot dip galvanized steel coil. A thin steel coil is dipped into a molten zinc tank so that its surface is adherent to a thin steel coil of zinc. At present, the continuous galvanizing process is mainly used for production, that is, the steel plate into a roll of continuous immersion in the melting zinc plating tank made of galvanized steel coil;
B) alloyed galvanized steel coil. This steel coil is also made by hot leaching, but immediately after the trough, it is heated to about 500℃, so that it generates an alloy film of zinc and iron. This galvanized coil has good coating tightness and weldability;
C) Galvanized steel coil. This kind of galvanized steel coil has good machinability by electroplating. But the coating is thin, corrosion resistance as hot dip galvanized coil;
D) Single side plating and double side difference galvanized steel coil. Single-sided galvanized steel coil, that is, galvanized only on one side of the product. In welding, coating, rust treatment, processing and other aspects, it has better adaptability than double-sided galvanized coil. In order to overcome the shortcomings of single side is not coated with zinc, and there is a galvanized volume coated with a thin layer of zinc on the other side, namely double-sided difference galvanized volume;
E) Alloy, composite galvanized steel coil. It is made of zinc and other metals such as lead, zinc alloy or composite plated steel coil. This kind of coil has excellent anti-rust performance and good coating performance. In addition to the above five, there are color galvanized steel coil, printing coated galvanized steel coil, PVC laminated galvanized steel coil and so on. But the most commonly used is still hot dip galvanized coil. Galvanized steel coil can be divided into general use, roof use, building outer plate use, structure use, wall board use, tensile use and deep punching galvanized steel coil.

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!
