In interior design, the most commonly used steel mainly has the following types:

Section steel is mainly divided into Angle steel, I-steel, channel steel, square pipe

Angle steel

Angle steel is a vertical Angle on both sides of the long steel, can be divided into equal Angle steel and unequal Angle steel. Angle steel can form a variety of different stress components according to different structural needs, and can also be used as a connection between components.



Angle steel, also known as Angle steel, Angle code, carrying capacity is less than the other three common types of steel, cheap, large-scale use in the indoor need for steel junction connection, usually used as a steel and floor connection.

Channel steel is a kind of long steel channel steel with a groove section, which is mainly used in building structure and curtain wall engineering.

Channel steel has good load-bearing properties. It is suitable for the base steel frame of materials and components with large self-weight, such as dry hanging stone, bathroom partition wall, etc., its function is similar to that of square tubes, and it is usually used together.

Zigzag steel

I-steel, also known as steel Beam (Universal Beam), is a long steel with a cross-section of I-shape. I-steel is divided into ordinary I-steel and light I-steel. The production specification is No. 10-60, that is, the corresponding height=100% is 10 cm-60 cm. Light I beam flange narrow, web thin, light weight, the same height=100%. Wide flange I-beams are also known as H-beams.



I-steel has the largest stability and load-bearing grade, and the price is more expensive than other prices. Therefore, it is generally used in the case of strong load-bearing levels, such as adding steel structure floors, steel structure stairs and so on.

Square tube

As the name suggests, a square tube is a square tube type, and many materials can be formed into square tubes. Square pipe is divided into structural square pipe, decorative square pipe, construction square pipe, etc.



Common specifications of square tubes are:20* 40,40 * 40,40 * 60,60 * 60,80 *80

The wall thickness is commonly used:3mm, 5mm, and the standard length of each steel is 6000mm.

Square pipe wall structure base

The square pipe frame is suitable for the base of indoor structure, its stability and construction convenience are better than Angle steel, but its stiffness is less than channel steel.

Note:When deepening the base frame, the size of the object steel frame specification should be considered. The size of the square pipe ADAPTS to the height=100% of the room.

For example, take wall dry hanging base as an example:20*40*3 is recommended for height=100% <2400mm, 40*40*3 is recommended for height=100% 2400-3000mm, 60*60*3 is recommended for height=100% 3000-6000mm, 80*80*3 is recommended for height=100% 6000-8000mm, Height >8000mm It is recommended to use 100*100 specifications is the safest, the relevant structure professionals should be accounted for.
