How to choose the proper circular hollow section for your project?

In the current steel pipe market, circular hollow section, square hollow section and rectangular hollow sections are the three main members of hollow structural sections. Galvanized steel pipes are the common circular hollow sections used in various applications around the world, which generally has the rational cost effective in the market. Compared with other typical steel pipe coatings, such as specialized painting and powder coating, galvanization is much more labor-intensive, resulting in a higher initial cost for contractors. Besides, due to its durability and anti-corrosive properties, galvanized steel pipe can recycled and reused, which to some degree save a lot of money during the post maintenance work. China hot dipped galvanized pipe has been considered as the popular circular hollow section among many users today. For one thing, the galvanization process protects the steel from rusting damage that can occur during transportation, installation and service. The zinc layer on the surface of pipe can form a barrier protection for steel products to extend the service life in applications. For the other thing, this layer is also resistant to wear and scratches, which makes the steel look more attractive.

Unlike other structural steel materials, galvanized circular hollow section is immediately ready for use when it is delivered. No additional preparation of the surface is required, no time-consuming inspections, additional painting or coatings are needed. Once the structure is assembled, contractors can immediately begin the next stage of construction without having to worry about the galvanized steel materials. Therefore, circular hollow section as one of the important structural steel pipes has been widely used for numerous construction projects, from the structures being built to the actual tools needed to complete the jobs. In most construction projects, circular hollow sections are used in many building types from small storage units to skyscrapers in big cities. For example, they are used to create the foundation of large buildings as well as other framework. Circular hollow sections are also used to construct balconies along with railing for staircases. As for their function with tools used for such projects, Circular hollow sections can be seen in the scaffolding workers rely on to reach tall points of buildings.

In recent years, some China steel tube manufacturers are committed to customized shapes as per the specific requirements of clients in the world. For example, the elliptical hollow sections have become more popular for architectural designs. Of course, you can often find that some other shapes of hollow structural sections have been used in a variety of infrastructure construction around us.
