Usage of Cold-Rolled C Bar:

1.The Cold-Rolled C Bar can be devided into two kinds, namely common channel steel and light channel steel. The sizes of CR rolled common channel steel range from 5# to 40#. Meanwhile, the channel steel can be divided into cold forming sectional equal channel steel, cold forming sectional unequal channel steel, cold forming inner edge channel steel and outer edge channel steel.

2.The Cold-Rolled C Bar 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. The channel steel with sizes under 14# is usually applied to construction engineering, as purline, while the channel steel with sizes above 16# is more likely to be used in building vehicle chassis structure and mechanical structure. Furthermore, the channel steel in sizes above 30# are target at building bridge structure, as tension bar.

3.In a word, the channel steel must possess perfect welding property, riveting property and mechanical property and so on.

 

 

Package & Delivery of Cold-Rolled C Bar:

1.The Cold-Rolled C Bar 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.

2. And the Cold-Rolled C Bar could be loaded into 20ft or 40ft container, or by bulk cargo.If the weight of each bundle reaches more 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.

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

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

 

 Cold-Rolled C Bar

 

Production Flow of Cold-Rolled C Bar:

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 channel should be put onto the cooling bed to make the temperature low.

4. The Cold-Rolled C Bar should be straighted on the straightener.

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

6. At the last part of production, the channel steel must be tested in order to confirm that the finished products are completely free from crack, pore, slag, scab or fold on the surface.

Q:What is the allowable bending strength of Q235 channel steel? Why does the mechanical manual have no bending strength?
The mechanical manual in the form of steel section properties, cross section characteristics of root bending strength is independent of the bending strength is related to the types of steel, so the bending strength in the mechanical manual in the form of representation, the strength of steel design value should be based on the steel thickness or diameter (according to different types of steel standard the table for data) is more complex, is designed by the staff according to the design requirements in the design code for.
Q:How to connect channel steel and round steel?
Vertical welding of channel steel and round bar axis:First, the channel steel, channel cut, need to connect the length of the arc shaped gap, and then again and round steel arc surface welding, welding before the two kinds of materials to rust, and full welding.
Q:12# how much is a channel steel? The length is 6 meters. GB steel channel should be used
Channel steel is a kind of carbon structural steel used for construction and machinery. It is a complex section steel. Its cross section has a groove shape. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing, etc..
Q:What does channel steel look like? Where is it usually used?
Channel steel is a type of steel, as its name suggests, is a groove type steel. Generally used for steel structure column, beam and ladder, electrical engineering general production of foundation buried parts, called basic channel steel. Because of its special shape and bearing capacity, it is also widely used in support structures.
Q:Can the bypass of the overhanging layer on the site be made of channel steel? How can I put the channel steel, if possible?
6.10.11 wall fittings shall be in accordance with the provisions of section 6.4 of this code. The main structure of 6.10.12 anchor steel shall not be less than C20
Q:Channel steel is a strip of steel with a cross section.
Channel 50 is [50]
Q:Do galvanized steel channels need anti rust treatment?
Just like roadside poles, most of them are hot-dip galvanized, and they also have to be passivated. Of course, if you apply the paint again, the rust proof effect will be better.
Q:Overhanging Scaffold; channel spacing?
Vertical spacing and verticality:Vertical pole and big cross bar must be fastened with right angle fastener, and the degree of fastening screw should not be less than 40N m, and should not be greater than 60N. M, and use the kilogram wrench to check before it can be used.The vertical distance of the scaffold vertical rod is not more than 1.5m, and the deviation is allowed to be set at + 5cm, and the vertical allowable deviation of the vertical rod is not greater than the 1/200 of the frame height, and not more than + 10cm.
Q:Is section steel the same as channel steel?
Channel steel is one of the types of steel, including channel steel, angle steel, I-beam, H steel, L steel, etc..
Q:What do you mean by channel 8 A?
It is usually said the channel No. 8 No. 8 channel, its height is 80MM, width is 43MM, no A and B channel No. 8 points, only a model, if the other channel with A and B, C, but its width is not the same, but always the same.
JANG is a professional company specilized in cold bend angle, cold bend U channel and other cold formed sectional steel. Since the established of our company, we aimed to provide the customers qualified product with good price and convenient service.
