What Are The Different Shapes Of Structural Steel

Steel is everywhere in the building, from the beam supporting the roof to the skeleton of the whole building, and then to the tools you use. However, steel is not just one thing - there are many different kinds of steel and different shapes of steel, each of which has its own purpose and purpose. Learn in detail how different types of structural steel are used in buildings.

Overview of structural steel

Structural steel is a metal used for building materials. Fundamentally, it is defined as steel optimized for building construction - different from steel that may be used for engineering tools, or stainless steel that is commonly used for kitchen surfaces and electrical appliances. Structural steel is usually carbon steel, which means that its chemical composition contains both iron and carbon. Structural steel is any type of steel whose carbon content does not exceed 2.1% of its total weight. The higher the carbon content, the higher the yield strength of the steel - which means that it is less ductile or less likely to bend or warp when pressure is applied.

Shape of structural steel

The following are the types of structural steel profiles commonly used in the construction industry:


1. Angled part: equal length or unequal length right angle L-shaped steel profile. These are usually used to support any type of steel structure, from connecting the steel bars together to supporting the steel bed frame.


2. Tubular hollow section: circular tubular section steel with high torsion resistance, which means that they are unlikely to twist under weight, so they are very suitable for bearing.


3. Flat part: also known as "plate", the flat part can be connected to other parts to enhance strength.


4. Parallel flange channel: the parallel flange groove is a U-shaped steel profile with right angle; These sections have a high strength to weight ratio, which means that they are usually relatively light compared to the loads they can withstand.


5. Rectangular hollow section: rectangular hollow sections are similar to tubular hollow sections except that their shapes are rectangular. They have high torsional resistance.


6. Square hollow section: square hollow sections are not as common as tubular or rectangular hollow sections because their shapes are not suitable for fusion with many other structural steel shapes. However, they are usually used in columns or columns of structures.


7. Tapered flange beam: also known as I-beam, it is similar to the letter "I" at its end. The tapered flange beam is usually used as the cross section of the girder. They have an overall high resistance ratio, but unlike hollow profiles of various shapes, they do not have high torsional resistance.


8. Universal beam: universal beam, which is called H-shaped beam because it is similar to capital letters or wide flange beam, is similar to tapered flange beam in shape and function.


9. Common column: common column is similar to common beam, but it is mainly used for vertical building column due to its excellent bearing capacity.
