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.
