Product Introduction

Steel hollow bar is a kind of metal bar with hollow middle section, often made of carbon steel and alloy steel. This bar is often used in mechanical manufacturing to make lightweight, high-strength parts, such as fan blades.
Its light weight and ease of processing and transportation make it more suitable than solid steel rods in some application scenarios. However, due to the cavity in its interior, its performance may not be as stable as that of solid steel rods in the case of strong force or high pressure.

What is a hollow bar
Product Application
Bridge construction
Steel hollow bars are widely used in bridge construction because of their high strength and light weight. Many components in a bridge need to withstand a lot of weight and pressure, and it can provide sufficient strength and bearing capacity, while reducing the weight of the overall structure, making bridge design more efficient and economical.
Construction industry
They are used as the main structural material. For example, the columns and walls of a building can be made of hollow steel to increase the strength and durability of the building. Its lightweight features make construction easier, while reducing transportation and installation costs.
Automotive and aerospace manufacturing
Hollow steel rods play an important role in automotive and aerospace manufacturing. Car frames, doors and other components need to be durable, lightweight and high strength, and it is the ideal material to meet these requirements. In the aviation sector, it is also used to manufacture some key components of aircraft to ensure their safety and stability.
Rail transit
They are also used to manufacture key components of high-speed rail trains, subway vehicles, tram tracks and other transportation facilities to ensure the safe and efficient operation of these facilities.
Mechanical parts and chemical equipment
Because of its excellent mechanical properties and corrosion resistance, stainless steel hollow bar is also often used in the manufacture of mechanical parts and chemical equipment. These devices often need to work in harsh environments, which can meet their requirements for strength and durability.

Advantageous Features
Lightness
The hollow bar is hollow inside design, compared with solid steel rod, its weight is lighter. This characteristic makes the hollow steel bar more convenient in the process of transportation, handling and installation, reducing labor costs and improving work efficiency.
Good wind resistance
Due to the existence of internal cavities, its structural design makes it have better stability in the face of external forces such as wind, so its wind resistance is better than that of solid steel rods.
Wide range of applications
Due to its lightness and good stability, it is widely used in machinery manufacturing, light construction, furniture, screens and other fields. Especially when the overall weight needs to be reduced while maintaining a certain structural strength, the advantages of hollow steel rods are particularly prominent.
Cost effectiveness
Compared with solid steel rods, the material use of this steel rod is more economical, so it has certain advantages in cost. At the same time, due to its good performance, it can meet the needs of many application scenarios, further improving its cost effectiveness.
