Choosing the right material is one of the most important decisions, directly affecting the load-bearing capacity, cost and durability of a construction. In the field of steel structures, there are many different types of steel, each with its own characteristics and scope of application. Understanding the types of steel structures will help engineers, purchasing departments and investors make the most optimal choice.
1. Hot-rolled structural shapes
This is a group of steel products formed at high temperatures. (above 1000°C), with a cross-sectional area that is not double along the length. They are mass-produced in metallurgical plants according to certain size standards.
H-beam
Characteristics: Has a cross-section like a capital H, with the flange and web having almost equal thickness, creating balance and good load-bearing capacity in both directions.
Application: Very popular for making columns and main beams in high-rise buildings, factories, bridges and roads due to its excellent bending and compressive strength.
I-beam
Characteristics: It has a cross section like a capital letter I, with the wings being narrower and thinner than the abdomen.
Application: Mainly used as secondary beams, purlins, or bending members in one main direction. Not as optimal as H-steel when used as columns.
U-channel and C-channel steel
Characteristics: Has a U or C shaped cross section.
Application: Often used as secondary beams, braces, wall supports, door frames, or in roof structures.
Angle steel
Characteristics: Also known as V-steel, has an L-shaped cross section.
Application: Widely used to make braces, struts, connecting details in truss systems and support frames.
2. Steel plate
Characteristics: It is a type of steel that is rolled flat into sheets with various thicknesses.
Application: It is an extremely important input material for the production of composite steel. In addition, steel plates are also used to make connecting plates, reinforcing ribs, steel floors, and in plate structures such as tank shells and silos.
3. Built-up members
Characteristics: These are not prefabricated steel but are manufactured components. combination from steel plates or profiles at a steel structure manufacturing plant. For example, a large I-beam can be made by welding 3 steel plates (2 for the flanges, 1 for the web) together.
Advantage: Allows the creation of components with non-standard sizes and shapes, optimizing load-bearing capacity according to design requirements. This is an extremely flexible solution for structures with large spans or special load-bearing requirements.
Application: Is the main component in pre-engineered steel buildings, factories, large-span houses, bridges, etc.
How to choose the right type of structural steel?
Choosing which type of steel depends on many factors:
- Function of the component: Is that member a column, main beam, secondary beam or brace?
- Load bearing requirements: What is the load acting on the structure?
- Architectural requirements: Shape and size of the project.
- Cost and availability: Which type of steel is economically optimal and easily available on the market?
Typically, structural engineers will be the ones to calculate and specify the most suitable type of steel in the design drawings.
