Hollow Bar

Hollow Bar is a tubular product with a hollow interior, meaning it has an empty space or void at its center. Hollow bars are commonly used in various industries for different applications.



Hollow bars can be made from various materials, including steel, stainless steel, aluminum, and other alloys. The material choice depends on factors such as strength requirements, corrosion resistance, and the specific application.


Construction: Hollow bars can be used in construction for structural components or as formwork in reinforced concrete.

Machining: They are often used in machining processes to create custom components with a hollow structure.

Fluid Transport: Hollow bars can serve as conduits for fluids or gases, particularly in hydraulic and pneumatic systems.

Shafts: Hollow bars may be used to create hollow shafts in various applications, such as machinery and rotating components.

Dimensions: The dimensions of hollow bars are typically specified by their outer diameter, inner diameter, and wall thickness. Common dimensions are specified in inches or millimeters.

Strength and Rigidity: Hollow bars provide strength and rigidity while often being lighter than solid bars of the same material, making them suitable for specific applications.

Welding and Fabrication: Hollow bars are easily weldable, allowing for customization and fabrication to suit specific project requirements.

Surface Finish: Depending on the material and application, hollow bars may have different surface finishes, including polished, coated, or untreated.

Seamless vs. Welded: Hollow bars can be seamless or welded. Seamless hollow bars are produced without a seam, while welded hollow bars are created by welding together pieces of metal.
