Cold formed structural steel pipe

When you are choosing materials for a project, it is important to know the difference between the different types of steel pipe available in the market, how it is used and the advantages of including it in your industrial or construction project. Structural steel pipes are very popular among builders which have been widely used in a variety of construction projects today. In North America, simple braced frames are more popular for the lateral load-resisting system and hollow sections are the typical choice for diagonal bracings. Such concentrically braced steel frames provide very good lateral strength and stiffness, with the bracings contributing to seismic energy dissipation by yielding in tension and buckling in compression during cyclic loading.

Cold rolled steel pipe is one of common steel pipes in today’s market, which has been rolled at room temperature, below its recrystallization temperature so as to increase its strength and hardness and decrease its ductility. In addition to improvement of mechanical properties, cold rolling results in more control over the shape and dimensions of the finished product. Cold rolled steel has an improved surface finish and tighter tolerances compared to hot rolled one. It is commonly used for parts requiring cold forming, such as crimping, swaging or bending. It can also be used for shafts, machinery parts, bolts, pinions, gears, as well as in the creation of furniture, appliances and other consumer goods. In Japan, Japanese building construction is governed by severe seismic loading criteria and proves an excellent case study for earthquake design of steel framed building. In such structures, moment-resisting frames are normally used to resist the lateral loads and square steel pipes are the leading column shape. In Japan, as in nearly all the world, structural steel pipes are cold-formed in various applications.

Today, China hollow section tubes play a vital role in the global steel pipe market. Every year, there is lots of cold formed structural pipes shipping into other countries around the world. China has become one of the largest steel product exporters in the recent years. With the further development of technology in the iron and steel industry, there is also another finishing between hot rolling process and cold rolling process, Pickled and Oiled. By being pickled in acid and oiled, the mill scale on the hot rolled steel can be removed and protect it from rusting.
