LSAW Steel Pipe

　　Different production process would give clients various types of square steel pipe. Today, for this kind of ERW steel pipe , we will have a comparison for the hot rolled and galvanized. 　　Hot rolled square steel tubing: due to its special strength, durability and ability to withstand extreme temperatures, it is usually used for domestic and industrial applications. With the process of welded, formed and drilled, it has a wide range of application for customers. 　　Galvanized square steel tube: it is easy to weld, cut, form and machine. The galvanized coating also allows for improved corrosion resistance over other types of carbon steels. In addition, galvanized tubes are a lower cost alternative to steel to achieve rust free protection for up to 30 years, while maintaining comparable strength with a durable surface coating.

　　In recent years, structure tubes is not only widely used in marine engineering and bridge engineering, but also widely used in industrial and civil construction. 　　More and more structure tubes used in China's building, In the use of square tube truss, Jilin skating Rink, Harbin Ice and Snow Exhibition Hall, Shanghai "Oriental Pearl" TV Tower and Changchun Nanling Gymnasium are using square steel pipe as the main structural components. 　　In the field of public buildings, some application of structure tube is unique, such as the Sydney Aquatic Centre, the United States Jarden Grove Crystal Church; single-storey space construction, except widely used in supermarkets, warehouses, there are also a number of very large structures, such as the Singapore Zhanghou Airport Hangar, the Osaka International Airport Terminal; in addition, there are also light large span structures such as pedestrian bridges and crane structures; other special usage of structure tubes can be ant...
