6 Useful Tips for Cold-rolled Rectangular Tubing (hollow section)

July 01, 2021

Cold Rolled Round Tubing (Hollow Section)
Seamless stainless-steel cold rolled rectangular tubing (hollow section) is manufactured without any welding process. Thus, the steel cylinders, in their solid form, are heated until they can be pierced.

Seamless stainless-steel tubes have applications in plumbing and conducting materials that require higher pressure. Projects that require the conduction of oil, steam, and hydraulic projects have greater reliability in seamless tubes.

Applications and advantages of seam and seamless stainless-steel tubes (cold rolled rectangular tubing (hollow section)

The difference between sewn and seamless stainless tubes is welding. Thus, the applications and advantages of each of the products will enhance when selecting the best option for your project.

Sealed stainless steel tubes, unlike the weld-free format, are the most affordable type on the market. Because of this, the stainless-steel tubes with seam gain an advantage when you have a simple project, but that demands quality.

The material finish of the sewn stainless cold-rolled rectangular tubing (hollow section) can be easily washed.

An important consideration before choosing cold rolled rectangular tubing (hollow section)

It is important when choosing sewn or seamless stainless-steel tubes, to take international safety standards into account. Check if your project allows the application of tubes that have gone through the welding process.

Final Considerations

The construction, mechanics, decoration, and other industries have different priorities when selecting the right materials. Therefore, it is important to consider the advantages of each of the sewn and seamless stainless-steel tubes.

As the stitched option is more affordable and cost-effective, it can be widely indicated in a variety of project applications. Check if the segment in which your company operates has specific needs in its projects. It is also worth prioritizing the ideal stainless-steel cold rolled rectangular tubing (hollow section) according to variations in size and thickness.

Cold Rolled Tubing Stainless Steel

Stainless steel is famous for the numerous properties that make it durable and attractive aesthetics. However, for this, some routine cleaning care is important. Looking beyond the visual aspect, when its application is in medical or kitchen-related items, cleaning the material becomes even more essential.

Cleaning the products will help ensure that stainless steel maintains its cleanliness and shine, remains free of impurities, or dirt and has an extended shelf life. To help you with this task, check out our tips below.

Good practices for light cleaning of stainless-steel products

First, be aware that it is not necessary to use heavy chemicals to clean stainless steel.

Thus, it is always important to read the recommendations and instructions for use contained in the cleaning product packaging, in order to identify any possible contraindication to stainless steel cold rolled rectangular tubing (hollow section) and all other products. To be even safer, you can test a non-visible part of the steel product to make sure the composition will not stain.

In general, for most routine use and cleaning products, hot water and a soft cloth or sponge is a good start. For kitchen items such as cutlery, for example, it is possible to add only dishwashing detergent for a satisfactory result.

Useful cleaning tips for removing residue and stains from stainless steel

For the removal of stains and watermarks, a glass cleaner is easy to use. Just sprinkle the compound on the product and then wipe it off with a microfiber cloth. Finally, rinse the item and buff its surface with a soft, dry cloth.

Now, if the residues or stains are more resistant on your stainless-steel cold rolled rectangular tubing (hollow section) or any other utensil, it may be necessary to use a sponge to apply the cleaner to the tube. Also, baking soda can also be helpful in these situations.

To do this, make a paste with a tablespoon of baking soda mixed with a little water.  Finally, rinse the piece and let it dry.

Other useful tips for cleaning and maintaining stainless steel
  • When cleaning, especially the heaviest, keep the environment well ventilated.
  • Keep in mind that polishing stainless steel only recommend for scratched or opaque surfaces.
  • For polishing stainless steel kitchen utensils, you can alternatively use vinegar or lemon juice.
  • Keeping stainless steel items dry at all times helps to prevent stains and ensure their cleanliness and great durability.
  • The most suitable products for cleaning this material are mild and neutral detergents, water, soap, microfiber cloths and, nylon sponges.
  • During cleaning, avoid making circular movements, especially if you use any product to polish or remove stains.
Is stain-less steel metal being more durable than others?

Unlike other metals, stainless steel remains, for many years, shiny and positive looking, without corrosion. This is due to the passive layer of stainless steel so your cold rolled rectangular tubing (hollow section) will remain damage-free for a long time.

In a corrosion process, the passive layer is responsible for ensuring that the stainless steel remains durable and can be used for the desired application.

In today's post, learn more about what it is and see the importance of the stainless-steel passive layer, as well as tips on how to choose a supplier for this material.

After all, what is the passive layer of stainless steel?

First, you need to understand how the concept of corrosion works.

The passive layer, in this case, is a kind of protective film that guarantees the stainless characteristic of the steel. It is a chemical protection inherent to stainless steel, which protects the cold-rolled rectangular tubing (hollow section) and other stainless-steel products from the appearance of rust.

In addition, the passive layer has the ability to self-regenerate. This is due to the presence of chromium in the passive layer, which continues to react with oxygen in the medium.

The stainless-steel passive layer is invisible to the naked eye, has a very thin thickness and is very adherent to stainless steel.

Why is it important to invest in stainless steel?

The importance and versatility of stainless steel for different projects and applications are enormous.

From household utensils to petrochemical industries like cold-rolled rectangular tubing (hollow section), stainless steel is present to ensure greater malleability in the manufacture of products, heat conservation in industrial equipment, and many other benefits inherent to the use of this metal.


The passive layer, although providing the resistance sought by stainless steel, is not the only characteristic responsible for the different applications of the material. Substances such as nickel, molybdenum, and carbon also have properties that ensure resistance to the material and make it suitable for different projects
