Angle Steel Series Products Introduction
Angle steel is one kind of important and commonly used multi-purpose structural steel in many constructions, so understanding and providing the appropriate angle steel is always important. The angle steel is made of structural carbon steel, which can be divided into hot-rolled angle steel and welded angle steel based on the combination of processing ways and production ways. Angle steel series, here in this article, is a detailed introduction to the specification, classification, properties and usage.
Classification and Specification
Angle steel is categorized based on both the side length and the angle. Generally, angle steels are classified as L-shape when the sides are equal, unequal when the two sides are of different lengths and unequal with radius when the two sides are equal and rounded at the corner. Moreover, based on the length, the angle steel can be classified as 3 different length series, which are 2,3 and 4 meter length. As for the angle specification, the angle steel can subdivide into the following types.
For 2 meter length series,
25x25x3, 30x30x3, 35x35x4, 40x40x4, 45x45x4, 50x50x5, 60x60x5, 65x65x6, 70x70x7, 75x75x6, 80x80x7, 90x90x7 and 100x100x10
For 3 meter length series,
25x25x3, 30x30x3, 35x35x4, 40x40x4, 45x45x4, 50x50x5, 60x60x5, 65x65x6, 70x70x7 over.
For 4 meter length series,
25x25x3, 30x30x3, 35x35x4, 40x40x4, 45x45x4, 50x50x5, 60x60x5, 65x65x6, 70x70x7 over.
Important characteristics of angle steel are the length of the two sides, the angle of the intersection and the thickness of the wall. Besides length and angle, angle steel has other specifications which include tolerance range, surface quality, straightness and deviation of the sides.
Properties
Angle steel is one important steel product with high strength, good plasticity and toughness, as well as good weldability and cold and hot pressure processing performance. It is widely used in industrial and civil constructions, such as bridges, steel structures, machinery parts etc. For example, the angle steel produced with Q345 or Q235 material (which is based on the main components of EN Standard) has good physical and chemical properties and is suitable for high-voltage transmission line tower manufacturing.
The general use of angle steel includes used as shipbuilding steel due to its resistant to corrosion from seawater, used as bridge steel due to its elongation and good plasticity, and can also be used in construction and highway. In addition, the angle steel has many other usage and advantages.
Usages
Angle steel has three main usages which are mainly related to its mechanical properties.
Firstly, angle steel has good plasticity which makes it suitable for both cold bending and hot bending in various sections. In this case, angle steel used for making various parts in machines, such as supports for machines, boxes for pumping machine, towers for steel structures and more.
Secondly, the angle steel has good weldability which makes it suitable for welding operations such as arc welding, submerged arc welding, gas welding and others. Thus, it can be used for making various shapes. For example, it can be welded to form rigid frames connecting support in various parts.
Finally, the angle steel has good stiffness, so it can be used as construction for various parts that require high stability, such as frame structures, floating bridges, Bridges and other external structural stiffening uses.
Conclusion
Overall, angle steel is one kind of very important structural steel product in many constructions, bridges and other structures. Different angle steel have different specifications, sizes and shapes. It is resistant to corrosion and suitable for both cold and hot bending and welding operations. In this article, a brief introduction is made on the classification, properties and usage of the angle steel, as well as some of the many use and advantages of this material.
