Applications of CR C Channel:

The CR C Channel can be applied to construction of warehouses, workshops, sport stadiums and car parks etc.The hot rolled channel steel belongs to carbon structural steel which is applied to in the field of construction and machinery.In details, the hot rolled 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 hot rolled channel steel we supply must possess perfect welding property, riveting property and mechanical property and so on.

 

 

Package & Delivery of CR C Channel:

1.The hot rolled channel steel 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 hot rolled channel steel 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.

 

 CR C Channel

 

 Production Flow of CR C Channel:

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

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

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

Q:18# channel perimeter
Channel 18#A 180*68*7.0 theory weight 20.174, section area 25.69, channel 18#B 180*70*9.0 theory weight 23, section area 29.29, average leg thickness 10.5, inner arc radius 10.5, leg end arc radius 5.25
Q:Channel 12, span 5 meters, how much weight can be carried?
Check the ordinary channel capacity should be B (i.e. limited channel material can only bear much of the force, this is the state), because the common channel is Q235 type steel structure, the allowable stress of [b]=1400kg/c square meters
Q:Is the crane telescopic arm welded by channel steel or by square tube?
Steel welding steel mostly used as a beam or a column, the steel plate is relatively thick, and the channel has been forming calculation immunity anti disturbance capability is greatly improved, two only in the center position of weld line position, the formation of the moment theory on the bending of the analysis should be small and therefore, whether it is welding crack or welding deformation can better handle. In no case have to supply square, to be.
Q:Is channel steel expensive or angle expensive?
Specific look at what type of equilateral angle iron, different specifications of the difference, the channel is also, 63*63 angle steel and 80 groove, usually about the same
Q:What is 16a# channel steel?
Model 160*63*6.517.24KG/ m. This model is called channel 16A
Q:Do galvanized steel channels need anti rust treatment?
Galvanized layer can play a good role in rust prevention, rust prevention can not be done anymore.
Q:Duplex building intermediate layer with channel steel or cast well?
Double story building, intermediate layer with channel steel and cast in place each has advantages and disadvantages, the following detailed description:1 、 cast-in-placeAdvantages: strong, relatively sound insulationDisadvantages: self importantMethods: in the load-bearing wall planting steel, tied with steel, formwork, pouring 10~12cm, waiting for about 28 days molding (summer time is slightly shorter)
Q:What kind of low carbon steel and medium carbon steel are they?
Low carbon steel is limited in use due to its low strength. Increasing the content of manganese in the carbon steel and adding some alloying elements such as vanadium, titanium and niobium can greatly improve the strength of the steel. If the carbon content in the steel is reduced and a small amount of aluminum, a small amount of boron and carbide are added to form the element, the super low carbon bainite can be obtained, and its strength is very high and good plasticity and toughness can be maintained
Q:Large steel channel used for steel structural staircases
Standard Specification for channel steel is C250*78*6TThe rest are flat steel strips and checkered steel plates
Q:Use two long five meters of 10# channel steel load-bearing frame, the maximum load is?
Set a span of 4.8m, two 10#Q235 channel parallel, as the beam, the required load is concentrated load, the role in the middle of channel.
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.
