Tubo estrutural

Structural pipes rank among the top sellers at TUSPIPE’s steel pipe manufacturing plant. TUSPIPE’s structural pipe offerings include not only circular structural pipe, rectangular structural pipe, and square structural pipe, but also hold certifications to international standards such as ASTM A500, EN 10219, JIS G3444, and AS/NZS 1163.

Tubo estrutural

Structural pipe (HSS: Hollow Structural Section) is hollow section tubing that is typically used in modern construction and engineering. Structural tubes are usually made of carbon steel, stainless steel and aluminum. The tubo estrutural are categorized into straight and bent tubes depending on the application requirements. Structural tubes are used in the construction industry as key components such as girders, beams and cable ties. In the machine building sector, they are responsible for equipment supports and supporting structures.

Types of Structural Pipe

Structural tubes usually cover circular, rectangular and square structural pipes and other shapes can be selected.

- Circular Structural Pipe: For Aesthetic and Structural Purposes

There are many types of structural pipes. Their uses vary. One is called a circular tube. This kind of pipe is usually made of hot-rolled seamless steel pipe and welded steel pipe. It has good bearing capacity and flexural stiffness, which can provide support structure weight, transfer load and stability for engineering projects. They are available in a variety of sizes to meet the needs of different applications. Circular pipes are often the material of choice for building structures, piping systems, etc.

- Rectangular Structural Pipe: Economical and Strong

Rectangular Structural Pipe has structural stability due to its rectangular section design. It boasts excellent mechanical properties. Physical properties of uniform wall thickness, high strength and high hardness. It not only realizes the visual linear beauty and geometric beauty, but also realizes the efficient load transfer and dispersion. Make it safe and reliable in natural disasters such as earthquakes.

- Square Structural Pipe: Aesthetics, Symmetry, Balance, and Strength

O square structure pipe is a kind of pipe that offers infinite possibilities for the application of structural purposes. Often used to create frames or support structures. For example, square structural tubes are commonly used to create frames for walls, roofs, and other types of buildings. Square structure tubes can also be used to create free-standing structures, such as sheds or storage rooms. It is also sometimes used in industry. For example, square structure tubes can be used to make supports for machinery or conveyor belts. Because of the good structural stability of square structure pipe, it is widely used in various fields.

Advantages of Using Structural Pipes

Structural tubes have unique advantages and a wide range of applications. Firstly, structural tubes have superior mechanical properties, due to their special cross-sectional shape, they can withstand pressure and bending with dispersed stress, and withstand larger loads and pressures. Secondly, it is economical and efficient. Reduced material weight, cost and transportation costs. On the other hand, structural tubes are usually made of steel. It has high strength and durability, e.g. for scaffolding or supporting structures. Compared to other materials, steel is less prone to corrosion, making it ideal for outdoor applications. Lastly, structural pipe has excellent workability and weldability, allowing it to be used flexibly in different types of application scenarios.

1. What Defines a Structural Weld?

Structural welding typically refers to welded joints used in load-bearing structures. Frequently employed in engineering structures, it strictly adheres to mandatory industry or national standards—such as the high-strength requirements of the AWS D1.1 Structural Welding Code in the United States—ensuring weld strength is no less than that of the structural tubing itself.

2. What Is Structural Tubing Used For?

Structural tubing primarily functions to withstand forces and bear loads. It is commonly used in the main frameworks of building structures, bridge supports or decks, and stage display frames. Its bending resistance, torsional strength, and adaptability make it stand out among modern structural steels.

3. Is Structural Pipe Seamless?

Structural pipe can be manufactured either seamlessly or welded. Seamless structural pipe lacks weld seams, offering excellent pressure-bearing capacity and uniformity. However, it is expensive, and the size range for large-diameter pipes is relatively limited.
