China hollow section tubes are popular in structure applications today

As we all know, the excellent properties of the tubular shape have been recognized for a long time. In the first part of the previous century, an Englishman, Whitehouse, developed the fire welding of circular hollow sections. However, the production of welded circular hollow sections became more important after the development of the continuous welding process in 1930 by the American, Fretz Moon. In the recent years, the first production methods for seamless and welded steel pipe have made great progress in the steel pipe industry.

Technically speaking, design is an interactive process between the functional and architectural requirements and the strength and fabrication aspects. In a good design, all these aspects have to be considered in a balanced way. Due to the special features of hollow sections and their joints, it seems even of more importance than for steel structures of open sections. Therefore, it is very important for you to choose the proper type of structural steel pipe in construction projects. In these years, China hollow section tubes play a significant role in the global steel pipe market. China hollow section tubes as an important building material used in the construction industry tend to serve a wide range of functions often, due to the good performances of durability, strength and resistance to harsh environment conditions. In the current steel pipe market, round steel pipe and square steel pipe are the popular building materials in construction. With steel, it's easy to expose the building's beauty in a design that will emphasize its grace, strength, transparency, and slenderness. The column-free clear spans and the use of colored steel pipe coatings bring out the natural lighting of the frame and its simple elegance. In construction projects, China hollow section tubes have many uses such as structural applications involved in residential, commercial and industrial construction. In particulars, as the flat square surface has the performance to ease construction, rectangular steel pipes are sometimes widely used for architectural aesthetics in exposed structures.

In the current steel pipe market, hot dipped galvanized steel pipe are very popular among builders. Many examples in nature show the excellent properties of the tubular shape with regard to loading in compression, torsion and bending in all directions. And these excellent properties are combined with an attractive shape for architectural applications. Furthermore, the closed shape without sharp corners reduces the area to be protected and extends the corrosion protection life in applications.
