Speaking of C-shaped steel, we have to think of channel steel. Why is this? The reason is that C-shaped steel and channel steel have too many similarities, so is there no difference between C-shaped steel and channel steel? Features? Obviously not, so what is the difference between C-shaped steel and channel steel?
First of all, what we should know is that from the perspective of production technology, compared with traditional channel steel, C-shaped steel can save 30% of materials with the same strength. It must be said that this is a great advantage of C-shaped steel. The reason The reason is that C-shaped steel is made of hot-rolled plate and cold-bent. It has thin walls and light weight. Its cross-section performance is extremely superior and its strength is very high.
In addition, we know that channel steel is produced by hot rolling, and its thickness is relatively large, and it is directly supplied by steel plants; but C-shaped steel is produced by cold rolling of strip steel (although it is also produced by hot rolling now), and its thickness is relatively thick. Steel is very thin and is generally supplied by steel structure factories.
Judging from their classification, there are also big differences. Generally speaking, channel steel can be divided into: ordinary channel steel and light channel steel. The specifications of hot-rolled ordinary channel steel are 5-40#. The hot-rolled flexible channel steel specifications supplied by agreement between the supplier and the buyer are 6.5-30#. Channel steel can be divided into 4 types according to its shape: cold-formed equal-edge channel steel, cold-formed unequal-edge channel steel, cold-formed inner curled channel steel, and cold-formed outer curled channel steel. But C-shaped steel is divided into: galvanized C-shaped steel, hot-dip galvanized cable tray C-shaped steel, glass curtain wall C-shaped steel, unequal C-shaped steel, inner rolled C-shaped steel, roof (wall) sandalwood C-shaped steel, automobile profile C Section steel and so on. From this point of view, from the perspective of classification alone, the difference between C-shaped steel and channel steel is also very obvious.
In fact, the easiest thing to distinguish between C-shaped steel and channel steel is their cross-sectional shape. The full name of C-shaped steel is cold-formed internally curled channel steel. From this, we can know that the cross-section of C-shaped steel has curled edges, while the channel steel has straight edges. From this point of view, C-shaped steel and channel steel are still very different. Easy to distinguish.
Finally, the two are also different from the application point of view. The scope of use of C-shaped steel can be said to be very wide. It is mainly used for purlins and wall beams in steel structure buildings. It can also be assembled into lightweight roof trusses, brackets and other building components; while channel steel is mainly used for building structures, vehicles In manufacturing and other industrial structures, channel steel is often used in conjunction with I-beams.
