hollowsection

A hollow section is a type of structural steel or aluminum profile characterized by its internal cavity, which gives it a distinctive hollow cross-sectional shape. These sections are widely used in construction and engineering due to their high strength-to-weight ratio, durability, and versatility. Common forms of hollow sections include rectangular, square, circular (also known as tubes), and sometimes elliptical profiles.

Hollow sections are manufactured through processes such as hot-rolling, cold-forming, or seamless tube manufacturing. Their hollow design allows for efficient load distribution and resistance to bending and torsional stresses, making them suitable for frameworks, supports, bridges, and various structural applications. Additionally, hollow sections are favored for their aesthetic appearance and ease of fabrication, including welding, cutting, and drilling.

In engineering standards, hollow sections are categorized based on their shape, dimensions, and wall thickness. They are available in various sizes to meet specific structural requirements, with steel hollow sections typically rated according to standards such as ASTM, EN, or JIS.

Advantages of using hollow sections include reduced weight compared to solid profiles, high strength, resistance to torsion, and efficient use of materials. They also facilitate the incorporation of services like electrical cables and piping within their internal cavities, especially in building construction.

Overall, hollow sections are a versatile and essential component in modern structural design, offering a combination of strength, efficiency, and flexibility across a broad range of industrial and architectural applications.
