The Different Types of Steel Sections Used in Construction

Types

There is no steel product that comes close to matching structural steel when it comes to strength and durability. This makes it a vital element for construction and infrastructure projects. However, not all steels are the same, so it’s important to choose the right type of metal for your needs. Luckily, there is a lot of information available to help you make the right decision. Here is a look at some of the most common types of steel sections that are used in construction.

Hollow section steel is a common type of metal that can be found in a variety of construction applications. These pieces are usually round or rectangular in shape and have a hollow center. They can be welded together to create larger structures. These types of steel are very durable and can withstand huge loads without sagging. They can also be easily bent or laser cut for specific uses.

Structural steels are a group of ferrous alloys that are used in a variety of construction projects. They have sufficient qualities at a relatively low price, making them a popular choice for many different sectors. There are many different grades of structural steel, and each one has its own properties and uses. The most commonly used ones are S235, S275, and S355. Each has its own unique characteristics that make it useful in different applications.

Applications

Steel sections are crucial for a wide range of construction projects. They provide structural integrity and support to various buildings, infrastructure projects, and mining applications. Different types of steel sections have their own strengths and weaknesses, which play a role in determining the ideal section for a particular application. Steel fabricators S235U section steel must consider the load-bearing capacity, structural stability, and design requirements of the project when choosing the appropriate section.

I-sections offer good axial-flexural capacity and are ideal for bracing members in a floor or purlin joist system or as a member of a roof truss. These sections have a high load-bearing capacity and excellent compatibility when connecting to other steel members or concrete/brick surfaces. However, these sections are prone to bending in the Y-Y axis and have limited applications in the X-X direction due to their unsymmetrical geometry.

Hollow structural sections (HSS) are a type of metal section with a circular, rectangular, or square cross-section. They are commonly used in load-bearing columns, welded steel frames, and industrial equipment. These sections have a low weight and a high strength-to-weight ratio, making them an ideal choice for multi-axis loading applications. These sections are available in a variety of shapes and sizes, so they can be customized to fit specific design requirements.

Strength

There are many different grades of steel available, which are mainly differentiated by their chemistry and durability. When choosing the right grade, it’s important to understand the conditions it needs to withstand and the load-bearing capacity that will be required.

When selecting a structural steel, you should also know the difference between its yield and tensile strength. Yield strength indicates the maximum load that does not cause permanent deformation, while tensile strength means that it can break under stress.

Depending on your application and the conditions, you may need higher yield or lower tensile strength. For example, laser cutting metal parts will require low tensile strength as the details are not loaded very heavily. Similarly, you would want high tensile strength if the details have to be bent afterwards.

S235U section steel is a popular general construction and machine steel that can be used in a variety of projects, including power transmission towers, elements of equipment, and automobile bridges. It is easy to machine and form, although it can distort when galvanised. Its comparatively low cost makes it ideal for building applications with limited budgets. It is also highly resistant to corrosion, making it a great choice for outdoor use.

Durability

The durability of a specific type of metal depends on the conditions that it’s used in. This includes the temperature as well, because some steels become more brittle at carbon steel plate suppliers lower temperatures and ductile at higher ones. That’s why it’s important to know what the specifics are when choosing a certain kind of metal. The number in the name of a particular steel grade indicates its tensile strength, which is the maximum stress that doesn’t cause failure. Anything over that value results in plastic deformation.

Aside from its ability to withstand loads, another advantage of S235U section steel is that it’s versatile enough for any purpose. As a result, it’s often used in buildings and other construction projects where builders need the material to meet specific requirements. It also makes sense when a building needs to be adaptable for future growth, because builders can add new sections to the structure without having to replace the entire frame.

If you’re considering buying S235U section steel, check the supplier for exact specifications. Some manufacturers may claim to sell the same material, but it’s essential to be aware of differences in quality and prices. It’s also a good idea to look at the chemistry of the metal and ask for the test results, so you can be sure that you’re getting a high-quality product that’s suitable for your conditions.
