Angle iron is very common in our daily life, especially for the friends who are engaged in real business. Although they say they are the same type of steel, there are still differences. Next, let me show you something about it
Difference between angle iron and angle steel
First, they are the same type of steel, but with different names. It is a kind of section steel specially used for making shelves. It has various shapes and many long holes, which is convenient for people to screw. It is mainly used for shopping malls, factories and individuals to make shelves. (it's like an aluminum alloy profile for windows and doors to make it convenient for people to use as a shelf.) this type of steel is called universal angle iron or universal angle steel.
2. Angle steel, commonly known as angle iron, is a long steel with two sides perpendicular to each other. There are equal angle steel and unequal angle steel. The width of two sides of an equal angle steel is equal. The specification is expressed in mm of side width × side width × side thickness. For example "∠ 30 × 30 × 3", that is to say, equal angle steel with side width of 30mm and side thickness of 3mm. It can also be represented by model, which is the centimeter number of side width, such as ∠ 3 ＃. The model does not represent the dimensions of different edge thicknesses in the same model, so the edge width and edge thickness dimensions of angle steel shall be filled in completely in the contract and other documents to avoid using the model alone. The specification of hot rolled equal leg angle steel is 2-20
III. The chemical composition of angle steel belongs to rolled steel series for general structure, and the main inspection indexes are C, Mn, P and s. According to the different brands, the contents are different, the approximate range is C < 0.22%, Mn: 0.30-0.65%, P < 0.060%, s < 0.060%.
Is angle iron the same as angle steel?
1. Angle steel is a carbon structural steel for construction, which is a simple section steel, mainly used for metal components and the frame of the plant. Good weldability, plastic deformation performance and certain mechanical strength are required in use. The raw billet for angle steel production is low carbon square billet, and the finished angle steel is delivered in hot rolling forming, normalizing or hot rolling state.
2. Angle steel is commonly known as angle iron. Its section is a long steel bar with two sides perpendicular to each other. Angle steel can be divided into equal angle steel and unequal angle steel. The same length of two vertical sides is equal angle steel, and the long and short ones are unequal angle steel. The specification is expressed in mm of side width × side width × side thickness.
If you want to buy angle iron and angle steel, you should pay attention to choose the right materials. Although there is little difference between them, there are still some differences in the specific materials. Consumers can choose according to their own needs. The above is about the difference between angle iron and angle steel. I hope you can know more about angle iron and angle steel.
