Product Description
Angle steel, commonly known as angle iron, is a long strip of steel that is perpendicular to each other and forms an angle.
There are equilateral angle steel and unequal angle steel. Its specifications are expressed in millimeters of side width x side width x side thickness.
The specifications of hot-rolled equilateral angle steel are 2#-20#.

1.What is angle steel?
Steel angle, also named angle iron, or steel angle bar, is basically manufactured by hot-rolled carbon steel or high strength low alloy steel. It has L-cross shaped section with two legs - equal or unequal and the angle would be 90 degree.
2.What is L-angle steel?
Angle Steel is 'L' shaped; the most common type of Steel Angles are at a 90 degree angle. The legs of the "L" can be equal or unequal in length. Steel angles are used for various purposes in a number of industries.
3.What are the disadvantages of using angle steel?
However, angle steel also has disadvantages such as low torsional stiffness, limited force direction, limited cross-sectional utilization, easy fatigue failure and high processing precision requirements.
4.Will angle iron rust?
The main enemy of angle iron is rust or corrosion, and any time bare metal is exposed to the air, rust will occur. This is especially true in areas that have been recently welded or worked with a grinder.
5.How to tell a 45 degree angle?
You can draw two perpendicular lines on a piece of paper. Then, divide the resulting right angle into two equal parts. Each equal part gives a 45-degree angle.
