What are hot rolled hollow sections?
Hot rolled hollow sections are steel profiles that are hollow in shape and are
typically used in the construction, transportation, and mechanical engineering industries. These hollow sections are created by rolling hot steel into a tubular shape and then allowing it to cool. The process of hot rolling involves heating steel above its recrystallization temperature, which makes it easier to shape and manipulate.
Hot Rolled vs Cold Rolled Hollow Sections
While hot rolled hollow sections are created by heating steel
above its recrystallization temperature, cold rolled hollow sections are produced by rolling steel at room temperature. As a result, cold rolled hollow sections have a smoother surface finish and tighter tolerances, making them ideal for certain applications.
However, hot rolled hollow sections have certain advantages over
their cold rolled counterparts, including higher yield strength and greater
ductility. Hot rolled hollow sections also tend to be more cost-effective than
cold rolled hollow sections, making them a popular choice for a variety of
applications.
EN 10210 vs EN 10219
EN 10210 and EN 10219 are standards that govern the production and use of hot finished and cold formed hollow sections, respectively. EN 10210 applies to hot finished hollow sections, while EN 10219 applies to cold formed hollow
sections. While both standards are similar in many ways, they have different requirements for the chemical composition, mechanical properties, and tolerances of hollow sections. EN 10210 also includes requirements for the production of seamless and welded hollow sections, while EN 10219 only applies to cold formed welded hollow sections.
Hot Finished Rectangular Hollow Section
A hot finished rectangular hollow section is a type of hot rolled hollow section that is rectangular in shape. These hollow sections are often used in construction and engineering applications, where they provide strength and stability while also being lightweight and cost-effective.
Advantages of Hot Rolled Steel
Hot rolled steel has several advantages over other materials, including greater ductility, higher yield strength, and cost-effectiveness. Hot rolled steel is also easier to shape and manipulate, making it ideal for a variety of
applications in different industries.
Bending and Rusting Properties
Hot rolled steel tends to be more ductile than cold rolled steel, which means it can bend and shape more easily. However, hot rolled steel also tends to be more prone to rusting than cold rolled steel, so it is important to take this into account when choosing the right material for your application.
EN 10210 and Yield Strength
EN 10210 includes requirements for the minimum yield strength of hot finished hollow sections. Yield strength is a key parameter used to measure the strength of a material, and it is an essential factor to consider when choosing the right hollow section for your application.
S355J2H Steel
S355J2H steel is a type of structural steel that is often used in the construction industry. It is characterized by its high strength, durability, and resistance to corrosion, making it an ideal choice for a variety of applications.
Uses of Rectangular Hollow Sections
Rectangular hollow sections have a wide range of uses in different industries, including construction, transportation, and mechanical engineering. They are often used as structural members in buildings, bridges, and other infrastructure projects, as well as in the fabrication of machinery and equipment.
Purpose of Hollow Structural Sections
Hollow structural sections are designed to provide strength and stability while also being lightweight and cost-effective. They are often used in construction and engineering applications, where they provide a reliable and durable solution for a variety of needs.
Conclusion
Hot rolled hollow profiles are an essential component of many industries, providing strength and stability while also being lightweight and cost-effective. Whether you are a construction professional, engineer, or manufacturer, understanding the differences between hot rolled and cold rolled hollow sections, as well as the standards and properties associated with these materials, can help you choose the right product for your application.
By considering the advantages of hot rolled steel, the bending and rusting properties of the material, and the various standards and types of hollow sections available, you can make informed decisions that will help you achieve your goals and meet your needs in the most efficient and effective way possible.
