What Are Round Bars?

A round bar is a long, solid metal bar with a circular cross-section and uniform diameter throughout its length. It is manufactured mainly through hot rolling or cold drawing and is available in materials such as carbon steel, stainless steel, alloy steel, aluminum, and brass. Because of their strength, durability, and easy machinability, round bars are widely used in construction, automotive, machinery, and engineering applications, especially for shafts, fasteners, and structural components.

Properties of Round Bars

Round bars exhibit the following key properties depending on material and processing:

  • High tensile and yield strength
  • Good machinability
  • Excellent corrosion resistance (in stainless/alloy steels)
  • Toughness and impact resistance
  • Hardness and wear resistance
  • Good weldability and formability
  • Heat resistance for elevated temperature applications
  • Magnetic or non-magnetic behavior depending on grade
  • High electrical conductivity for copper/aluminium bars

At Kalpaturu Piping Solution, grades are carefully selected based on service conditions to deliver optimal performance, safety, and longevity.

How Are Round Bars Made?

Round bars are primarily manufactured by:

Hot Rolling

  • Raw billets are heated to a plastic state
  • Passed through rolling mills to achieve cylindrical shape
  • Followed by straightening, cutting, and surface finishing

Cold Drawing

  • Pre-cleaned bars are drawn through precision dies at room temperature
  • Produces tighter tolerances and superior surface finish
  • Annealing may be used to relieve internal stresses

Hot rolling is preferable for large volumes and economy, while cold drawing is chosen where precision and finish are critical.

FAQ’s About Steel Flanges

Steel flanges are mechanical components used to connect pipes, valves, pumps, and other equipment in a piping system. They provide a secure joint that can be assembled or disassembled easily for maintenance or inspection. Flanges are widely used in industries such as oil & gas, petrochemicals, power plants, and water treatment.
A flange is used to join pipes, valves, pumps, and equipment securely, allowing for easy assembly, disassembly, and maintenance. Flanges also help align piping systems, provide leak-proof connections, and allow for the attachment of gaskets and seals in high-pressure or high-temperature applications.
Yes. Flanges can be customized in terms of size, pressure class, material, face type (raised face, flat face, ring type), and special coatings to meet project-specific requirements and international standards.
