1.We are able to provide channel steel of top quality at attractive price.

2.Our products of channel steel have passed ISO9001:2008 Quality Management System Certification.


Usage/Applications of JIS Standard Hot Rolled Steel U Channels:

Channel Steel is usually used for building structure, vehicle manufacturing and other industrial structure and often used with i beam.

In details,  the channel steel belongs to carbon structural steel which is applied to in the field of construction and machinery. The channel steel  is usually used for arch-itechtural structure, and they could be welded in order to support or hang a vari-ety of facilities. They are also usually used in combination with I beam. Generally,the channel steel must possess perfect welding property, riveting property and mechanical property and so on.


Package & Delivery of JIS Standard Hot Rolled Steel U Channels:

The steel u channel will be packed in  bundle with steel wire at each end of every bundle and color marking in order to help the customer to recognize his goods more easily at sight.                                                                                              

And steel u channel could be loaded into 20ft or 40ft container, or by bulk cargo. If the weight of each bundle reaches less than 3.5 mt, the loading by break bulk cargo should be choosed. When the weight of each bundle reaches less than 3mt, the loading by container should be choosed.                                                                                                          

As for the transportaion from mill to loading port, the truck will be usually used. And the maximum quantity for each truck is 40mt.                                                                                                                                                                        

All in all, we could do in accordance with customer's request.

Production Flow of JIS Standard Hot Rolled Steel U Channels:

1.The steel billet shall be heated in the high temperature furnace.                                                                                      

2. The heated steel billet shall be rolled five to nine times with the aim of shaping the general figure of steel u channel.        

3. The rolled steel u channel should be put onto the cooling bed to make the temperature low.                                          

4. The steel u channel should be straighted on the straightener.                                                                                        

5. The straighted steel u channel will be cut into meters by saw, as per customer's requirements.

Q:How about the Y-Y moment of inertia in the form of hot rolled channel steel Iy?
Among them, H, B, D and T are the corresponding parameters on the standard. B leg root thickness, a thickness of leg point or T = (a + b) divided by 2, R for leg root radius, R leg tip radius, Z standard centroid value, ^2 said in front of the results in parentheses square, ^3 cube, X said after the power multiplied by the other the local sign is omitted, said by slash.
Q:How to connect channel steel and round steel?
End face of channel steel and end face of round steel:Can first welding a large circular steel plate and steel bar etc. in the channel to the end faces of the circular plate thickness should be more than 10mm, then the circular plate side angle steel and round steel bar to coincide welding, chamfering, need full welding between the two.
Q:Is channel steel cold rolled or hot rolled?
According to the theory of steel structure, it should be stressed by the channel plate, that is to say, the channel should stand rather than lie prone.
Q:Surface area of channel steel
20A channel steel is 200mm in height and 73mm in width.Area = length * (200*2+73*4)
Q:What is the concept of nonstandard channel steel compared with the national standard channel steel? Is there any difference in size between the national standard channel steel and the material?
Non-standard channel steel, with channel steel waist height, leg width, waist thickness and per meter weight as the standard, non-standard channel steel, mainly in order to not affect the safety quality of the premise of cost saving, in high, wide and thick discount. For example, 12# channel weight per meter 6 meters for 12.059kg, 72.354kg, and 12# 6 if a channel is 48kg, then we call it under 33.3% (1-48/72.354). In our country, most of the steel market has sales of non-standard profiles, this is called "cut foot".
Q:Channel bearing capacity
Under the maximum bending moment calculation formula: M=1/8GL?? -1/8gL??, (L=600cm, G: the calculation of the maximum uniform load, G: ibid.)
Q:Use the No. 10 channel steel as the crossbeam, the span of 2 meters, the load is 300kg. How about the selection and the type of the channel steel? If not, what number should I use?
These problems are related to the calculation of the checking and checking results. It is better for you to draw a diagram to explain the above.
Q:Channel steel is mainly used in building structures
They are divided into ordinary channel steel and light channel steel. The specification of hot-rolled ordinary channel steel is 5-40#, and the specifications of the hot rolled channel steel supplied by both sides of supply and demand agreement are 6.5-30#.
Q:Large steel channel used for steel structural staircases
If not sure, can see 15j401 Gangti atlas. Choosing proper channel steel can not only ensure the structural safety, but also achieve the goal of saving the cost! Hope to help you!
Q:What is the difference between channel steel and C steel?
Channel steel is rail steel, relatively thick. C steel is rolled by iron plate
