Often, when shipping large modules, such as tanks, boats, or construction equipment on container vessels, there are challenges in loading and securing them at the port of origin, and there can also be similar problems at the port of discharge.

In addition to loading larger items as breakbulk cargo, the containers must also be stowed on a bed of flat racks that are installed on board first. For the vessel operator, this means additional time and special arrangements must be made for shipside operations, as well as an increase in costs for the shipper.

Additionally, shipping options for breakbulk may only be available on direct (port-to-port) sailings, thereby causing frustration for shippers who wish to access those markets served by transshipment container services as well.

The term flat rail for skateboarding refers to a metal pole that sits horizontally on the ground. Ben Dillinger FS Feeble. You will see flat rails in skate parks with different heights and lengths. You can get element round bars and square rails, as well as flat rails with kinks and curves that can be ridden on.

Many skate parks have flat rails with a wide variety of heights and lengths. You will find flat rails with round and square variations as well as flat rails that go around curves and have kinks in them.

On a flat rail, you can do all the grinds and slides that you like. However, it is a lot more difficult to balance on a narrow metal bar than on a curb, because it is narrower in diameter.

Building support materials such as flat bars are common in the construction industry. They are used for support braces, ladder hangers, gate latches, ductwork, overhead doors, heaters, and bracing.

Uses For Flat Bars

With a flat surface and a rectangular face, a flat bar skateboarding is extremely versatile and can be used for a wide variety of projects. Here are four of the most popular uses for skateboarding flat bars:

1. Frame Construction: Because metal bars can withstand construction weight, they are frequently used for frameworks. They can be easily cut to length and drilled or welded into place.

2. Building Support : Building support materials such as flat bars are common in the construction industry. They are used for support braces, ladder hangers, gate latches, ductwork, overhead doors, heaters, and bracing.

3. Improvements & Additions: Besides being used during construction, flat bars can also be used post-construction to reinforce existing structures. They can be easily cut and formed to match, replace, or support existing materials.

4. Industrial Artwork:  The flat bar is a popular choice for industrial artists and craftsmen who work on large-scale industrial pieces – most notably statues. Flat bars have a malleable nature and are extremely sturdy once forged.


Flat profile rails have been around a respectable 35 years and round-rail technology has honed to near perfection over the last 60 years. The inherent design problems have long been ironed out, and materials have improved dramatically. Most problems arise from misuse and misapplication. Misapplication is largely the result of personal bias, a miscalculation, or aesthetic judgment. The reason is that a relatively small linear profile rail might fit the load, the speed, and all the other parameters-just fine. However, when it is mounted on the machine, a discerning eye might conclude that it looks feeble and definitely undersized.



Round rails were regarded as the ideal linear motion-control solution prior to the advent of square rails. But as machine-tool users demanded closer tolerances for certain jobs, machine makers preferred the classical milling and scraping methods. When tolerance requirements could not be met, round rails were used for peripheral equipment.

As a result, skateboarding round rails have not become obsolete or less valuable. Their benefits continue to outweigh their drawbacks. Round rails are typically less expensive than square rails, but this should not be the primary criterion for any application. A square rail can actually fail whereas a round rail works flawlessly. For example, round rail skate are more forgiving of misalignment, poor parallelism, and moment loads in most machines and allow more variation in rail height than square-rail systems. They can still maintain a travel straightness of 0.01 inches for a distance of 10 feet. Also, the small rolling element tends to make the round-rail motion more smooth as a result of the small rolling element.

It is important to note that while many rails are supported at several points or along their full length in order to achieve this level of accuracy, only the ends need to be supported. This ensures that the rails are able to cross over gaps without a problem, and they can safely move from one support to another. It is much less expensive to prepare the round-rail system when it only requires a shaft-rail assembly (a shaft and rail, or a shaft and two end-supported blocks supported by four pillow blocks). Round rails tend to be relatively easy to install and relatively inexpensive to replace. In addition, round rails are relatively easy to service and replace.

Details of the Round Rail

Round rails are commonly used as handrails, guardrails, and safety barriers on stairs, balconies, walkways, and industrial facilities. Round rails can be described as follows:

  1. Materials: Round rails can be made from metals (such as steel, aluminum, and stainless steel), wood, and plastic. Choosing a material depends on the application and desired characteristics, such as strength, durability, and aesthetics.
  2. Depending on the application and load-bearing requirements, round rails can vary in diameter. The most common diameter ranges from 1 inch to 2 inches, but larger and smaller sizes are also available
  3. Depending on the application, round rails can have a straight or curved cross-section. In staircases and other areas where smooth transitions are needed, curved rails are often used.
  4. It is possible to finish round rails in a variety of ways, including polishing, brushing, or texturing. Rails’ surface finish can affect their appearance and durability.
  5. Round rails can be installed using a variety of methods, such as welding, bolting, or using specialized fittings. Material, application, and load-bearing requirements determine the installation method.
  6. Round rails are often required to meet minimum height, spacing, and load-bearing requirements under building codes and safety regulations.

The round rail provides a secure handhold and a safety barrier in a variety of settings, and its characteristics can be tailored to meet specific needs.

Uses of Flat Bars vs Round Rails

Both flat bars and round rails are commonly used in construction and industry for structural support, handrails, and framing. In spite of this, they have some differences in their characteristics and uses:

The versatility of flat bars allows them to be used in a variety of applications, including braces, supports, and framing elements. Metals such as steel, aluminum, or another metal are commonly used for making them, and they usually have a rectangular cross-section. Buildings, bridges, and other structures use flat bars as structural supports because of their durability and strength.

Round rails, on the other hand, have a circular cross-section and are commonly used as handrails, guardrails, and safety barriers. They can be found on stairs, balconies, and walkways and are typically made from metal or plastic. As a result of their ease of grip and ability to provide a secure handhold, round rails are most commonly used in these applications.

A flat bar is commonly used for structural support and framing, while a round rail is commonly used for safety barriers and handrails. They can, however, be used for a variety of purposes depending on their application and the material they are made of.
