Steel structure installation project is a very big project, the quality requirements are very high, steel structure as the most critical of the project of a kind of infrastructure, we need to consider what factors when choosing steel?
Heavy industrial building structure, large span structure, high-rise or super high-rise civil building structure or structures and other important structures, should consider the selection of good quality steel, for general industrial and civil building structure, can be selected according to the nature of the work of ordinary quality steel.

There are many kinds of steel plate, different types of products have different advantages in the use of the process, we can also look at the specific use of the site? Through a detailed understanding of the ability to better choose and buy, but also can ensure the use of the time to play a better role.

The non-uniform deformation of seamless steel tube becomes the residual stress after cold drawing under additional stress.Precision seamless steel tubes are widely used.General purpose seamless steel tubes are rolled from common carbon structural steels, low alloy structural steels or alloy structural steels to achieve the highest yield and are mainly used as conduits or structural parts for fluid delivery.Seamless steel pipe has a hollow section, a large number of fluid pipeline, such as the transportation of oil, natural gas, gas, water and some solid materials pipeline.Compared with round steel and other solid steel, steel pipe has the same bending and torsion strength and lighter weight. It is a kind of economic steel section.

​China's steel can be divided into profile, pipe, plate and metal products of four types, these types of steel tubes for the development of China's industry play a different role.Today, let's take a look at one of the industrial raw materials of I-steel what role it has.
