Introduction of Pre-galvanized Hollow Sections

The Pre-galvanized Hollow Sections is a versatile product. It comes in round shape. And it is very helpful in industrial applications such as:

  • sugar and alcohol
  • pulp and paper
  • Shipbuilding
  • construction area
  • among many others

For this type of tube to deliver the best result for your project.

it is important to look for reliable companies that follow, for example, the technical standards and norms go through inspection bodies. Learn more about this type of tube, its characteristics, manufacturing process. You can also learn where to find reliable companies to obtain quality tubes for your projects.

Meet the Hollow Sections with Saw Seam

The Pre-galvanized Hollow Sections Sections with Saw Seam is very resistant. It comes of carbon steel, common for conducting liquids and gases. On the market we find a variety of diameters, thicknesses, and lengths. Moreover, this serves different types of applications. It has the name “calendered” because it is produced using the calender.

Generally,  it is modern machine that gives the calendered steel tube a rounded shape. Moreover, it is a type of structure widely common as support in civil construction and foundation support, especially in maritime works. It is also present in many other sectors. Where to find reliable companies to obtain quality tubes for your projects.

Present in other sectors such as:

  • Automotive;
  • Rail;
  • Naval;
  • Mining;
  • Paper and Cellulose;

Sugar and alcohol;

It stands out a lot in large civil works projects, such as stadiums, railway stations, shopping centers, airports, etc. It is a type of tube very popular for its high resistance. This performs good especially in harsh environments, and also for the measurement options it has.

Excellent element for bigger and better structures

As a steel tube, an excellent element that allows for bigger and better structures, according to the architects' point of view, it is still very much in demand. The Pre-galvanized Hollow Sections with Saw Seam has characteristics. Similarly, they are very favorable to the industry, one of which is the variety of materials.

We can find round, square, rectangular, and oblong tubes, with profiles: "U" simple, "U" stiffened, "l" electro-welded, "l" laminated, "U" laminated, top hat, laminated flat iron, laminated square iron, iron “T” laminated. It also attends to special designs with “Z” profile and others, depending on the customer's order.

Main features and advantages of Hollow Sections with Saw Seam

The Hollow Sections with Saw Seam has several advantages. These allow different applications and offering good solutions in robust systems for conducting liquids and gases. It is a very popular tube due to its many benefits such as:

  • Resistance to harsh environments;
  • Flexibility;
  • Diversity in the number of measures;
  • Precision;
  • Great productive performance results;
  • Great cost/benefit.

In addition to all these advantages, the Pre-galvanized Hollow Sections Sections with Saw Seam is produced with achieving greater durability, strength, and useful life for its component.

These tubes also offer a good financial return for the company, as they are easy to apply, with quick installation, which avoids production downtime and favors the entire system. There is also the Hollow Sections of Stainless-Steel Sheet, a model that is much sought after in the market as well.

Some types of stainless steel have a corrosion defense mechanism, which is very useful in chemical industries that work with corrosive substances daily. There are many models and pipe materials available, but the idea is to choose the one that best suits your project and objective.

Pay attention when purchasing your calendered tube

In general, Hollow Sections with Saw Seam has great corrosion resistance, due to the quality of the materials common in its production, some of which are carbon steel, aluminum, and stainless steel. As we have already mentioned, it is a type of tube that has a wide variety of sizes and thicknesses.

Pay attention when purchasing your calendered tube, choosing one that is high quality, and making sure that its performance will meet all expectations. Check some relevant information about the companies that manufacture this item, so that you can make a good purchase.

The Manufacturing Process of Hollow Sections with Saw Seam

Saw Seam Pre-Galvanized Hollow Sections are made by bending and welding wide steel sheets and are widely common in oil and gas applications. Its manufacture comes through the calendaring process, in which different metals such as carbon steel, stainless steel, and aluminum are common.

In this process of manufacturing the Hollow Sections with Saw Seam, a flat carbon steel sheet is transformed into a tube shape through calendering. A machine that has high torque capacity and precision, twists the steel and gives rise to the curved shape of the tube, favoring a good connection.

The Manufacturing Process of Hollow Sections with Saw Seam

The part is finished with longitudinal welding with a large diameter, providing a complete seal, without flaws, discontinuities, making the Calendered Steel Tube one of the best industrial equipment on the market. It is very rare for this type of pipe to be common for applications with lower non-energy values.

Saw Seam Pipe competes against ERW pipe and seamless pipe in the 16” to 24” diameter ranges. To manufacture this type of tube more accurately, it is very important to look for specialized professionals. The Pre-galvanized Hollow Sections Pipe with Saw Seam needs to be easy to install so that it is possible to save labor.

How to get effective results?

For the result to be effective, all manufacturing steps for these tubes must undergo rigorous quality control. Essential parts in industry and present in homes, difficult to be understood, we are talking about Industrial Check Valves. Although they are small items and go virtually unnoticed.

Electro-galvanized steel comes by electroplating a pure zinc coating on either one or two sides of a carbon steel sheet or strip. Before mixing in a bath of molten zinc, the steel must pass a surface preparation process, including caustic cleaning, pickling, and fluxing.


They are also present in homes, particularly in the bilge pump or in a cistern pumping system. They comein the pump discharge line. Valves play a very important role in many industrial systems.
