?GI steel coil with spangles made in China
is a semi-finished material. It is widely used in many industries. The reason why it is galvalume is to give the material excellent rust and corrosion resistance to improve the finished product. The comprehensive performance and long service life can adapt to use in many different environments.
GI steel coils are also classified as cold-rolled or hot-rolled in the same way as other steels. In terms of price, the cost of cold-rolling is lower and the price is also lower, but the rust-resistance is poor if the performance is high. The hot-rolled material is selected. Although the price is relatively high, the performance is good and the quality is stable. It is used for production and production, and the quality of the finished galvalume steel coil is also reliable and has a long service life. This is because the hot-dip plating method is complicated, there are physical changes and chemical changes in the engineering, the coating texture is uniform and stable, so the adhesion is also strong, and it is easy to fall off without cold rolling, and the material itself also obtains high toughness and strength. It is not easy to break during processing, reducing the loss of materials.
If you don't know how to choose GI steel coil products, then you can choose to buy well-known companies with a good reputation and a good reputation. You can tell your needs, they can provide professional advice and suggestions, so as not to buy them. Or materials that do not meet your needs, resulting in waste. Generally, the materials commonly used in the market are classified according to the amount of galvanizing, and the corresponding materials should be selected according to actual conditions.
