How to select the proper type of hollow section tube in your project

China hollow section tubes play a vital role in the global steel pipe market today, which have been widely used in a lot of large construction projects around the world. For example, China hollow section tubes are widely used in greenhouse frame projects because of its cost effective, maintenance-free corrosion protection system that will be able to last for decades even in the harshest environments. However, before starting your next project, are you ready for selecting the proper type of hollow section tube?

In the current steel pipe market, structural steel pipes are very popular and have been widely used as frame materials in construction projects. Especially galvanized steel pipe 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. Unlike other structural steel materials, galvanized steel 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.

At present, seamless steel pipe and welded steel pipe are two common types of hollow structural section in use. welded hollow sections with a longitudinal weld are mainly made employing either electrical resistance welding processes or induction welding processes. Hollow sections, especially CHS, have the most effective cross section for resisting torsional moments, because the material is uniformly distributed about the polar axis. 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. China hollow section tubes are available in many forms for intended purposes other than greenhouse building, which can be adapted to many shapes and sizes of cold rolled steel pipe as per the specific requirements you would like in applications. If you’re building a greenhouse, choosing which type of frame to use will be one of your first decisions. And it is obviously important for most users to select a proper type of pipe frame to supports the entire greenhouse structure.
