4 Advantages of Round Bars

What are the advantages of round bars?

  1. High strength
  2. Comes in different shapes
  3. Malleable
  4. Excellent surface finish


Round bars are thick, pre-finished metal products that come with a circular base. Also referred to as bar stocks, round bars are primarily used in applications that require shafts or rods. They may be manufactured in different diameters — from ¼-inch to large, 24-inch thick stocks for heavier-duty use. For this reason, round bars have to be made out of durable raw metal or alloy, such as steel, aluminum, iron, or titanium. Industries may depend on either one or two of these metals, nevertheless, the advantages of round bars continue to make them one of the most formidable materials to achieve excellent load-bearing capacities and aesthetic finish.

Some of the advantages of the round bar are its high strength, versatility, malleability, good surface finish, corrosion resistance, and adaptability. The steel round bar, for example, is perfect for use in extreme conditional environments due to its high melting point. Other variations like aluminum can be bent and formed to accommodate structural requirements. Read on to learn more.


High Strength

Depending on the kind of metal used in the production of round bars, the strength will be variable. As mentioned before, steel would be one of the go-to materials for any application that requires durability due to its composition.

A high carbon steel round bar has a significantly high melting point between 1425 and 1540℃. Its near non-destructiveness, especially in extreme temperature and pressure environments. For example, when used as part of an automotive vehicle’s suspension and shaft systems, the high carbon round bars are dependable. This is because they can sustain quality even when exposed to high amounts of heat produced due to the combustion process.

Round bars are also often found in construction, where they are used for their load-bearing capacities — think roof decking, trusses, wall studs, scaffolding, concreting, welding, and many more.


Comes in Different Shapes

While there are standard sizes for round bars, they can be formed in different shapes and sizes that fit the preferences of the customer. Aside from the common elongated sizing typical of stock metal parts, the round bar may also take the shape of a puck or a small metal rod that has a smaller cross-section.

Other designs may also be carried out on the round bar. When cold-formed, for example, the lower internal stresses set the perfect conditions for the round bar to undergo further cutting and fabrication. The round bar can be cut, sheared, or even stamped in order to be compatible with other fittings, couplings, metal connectors, and the like.

Due to the different sizes available for the round bar, industries can use it as they see fit, and take advantage of the low upkeep required for the round bars.

Aside from aluminum, titanium, steel, and iron, some examples of metals that can be used for the round bar are copper, tin, and bronze. These materials are easily malleable, allowing fabricators and manufacturers to manipulate them with ease.

Round bars don’t really require expensive equipment to manufacture, unlike stamped parts which have to go through press breaks or even CNC machinery. Instead, simple production techniques like milling, grinding, and casting are used in round bar production. This is beneficial for both manufacturers and customers, especially when meeting demand and supply.

The low-cost production makes the round bar readily available and reduces overhead expenses for automotive manufacturing, construction, petrochemical refinement, and many more.


Excellent Surface Finish

The round bar can also sport an excellent surface finish by undergoing a metal finishing process. Plating, for example, can improve the luster of a stock metal round bar by adding another thin layer of zinc, chromium, cadmium, or nickel. Whereas simple brushing and cleaning can eliminate any surface defects or imperfections on the round bar to create a smooth and consistent surface body.

Metal polishing will produce different types of surfaces on the round bar, making this useful for end-users who want to improve the appearance, as well as enhance the functionality. Zinc plating, for example, can create a corrosion-resistant layer on the round bar. This is useful for ferrous materials such as steel and galvanized iron, as the zinc layering protects the material from undue corrosion and degradation.


Key Takeaway

Easy to manufacture and readily available in the market, round bars have been benefitting many industries for several decades, wherever a high-strength and low-maintenance material is needed.

As discussed, some of the advantages of round bars are their sturdiness, malleability, versatility, and high-quality surface finishing. Granted, there may be variations of these properties, depending on what kind of metal was used for the round bar, but the wide selection allows customers to find the best one based on the advantages.
