Tianjin rectangular steel pipes are very popular in the world today

In the current market, all the hollow sections steels are ERW steel pipe before being formed into square or rectangular section. Rectangular steel pipe has been widely used in structural applications in residential, commercial and industrial construction.

Tianjin rectangular steel pipes offer advantages of corrosion protection in applications. Some hollow sections have rounded corners resulting in a better protection than that with sharp corners. This is especially true for the joints in circular hollow sections where there is a smooth transition from one section to another. Meanwhile, this better protection increases the protection period of coatings against corrosion. Besides, Tianjin rectangular steel pipes have the ability to ease building frames in applications which are sometimes preferred for architectural aesthetics in exposed structures. Especially galvanized steel pipe can be recycled and be reused in projects, which to some degree save a lot of money during the post maintenance work. Besides, 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.

As it is well acknowledged, mild steel pipe is highly resistant to shock and vibration. Tianjin mild steel pipes are very popular in greenhouse frames because they are durable and safe. Building materials underground may be susceptible to rotting and pests. Steel will not rot and is impervious to pests like termites. Steel also doesn’t need to be treated with preservatives, pesticides or glue, so it is safe to handle and work around. Since steel is non-combustible and makes it harder for fire to spread, it is good to use when building homes. Steel frame buildings are more resistant to natural disasters like tornados, hurricanes, lightning strikes, and earthquakes.

Every year, lots of customers from different countries come to Tianjin to seek for their desired steel pipes. In the current steel market, besides the ordinary types of hollow sections, such as circular, square and rectangular hollow sections, some other shapes are also available for certain applications in life. Today, steel pipe 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.
