Usage of JIS Channel Steel:

1.The JIS Channel Steel can be devided into two kinds, namely common channel steel and light channel steel. The sizes of hot 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 steel u channel  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 JIS Channel Steel:

1.The 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 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.

Production Flow of Steel U 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 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.

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 are the acceptance criteria for channel steel?
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.
Q:How is the hollow tempered glass mounted on the channel steel?
Hollow two pieces of glass, there are 4 faces, from outdoor to indoor is defined as 1-4, Low-E glass film surface can only be in the cavity, that is, can only be second or third.Colorless, highly permeable Low-E is placed on third sides (Low-E glass indoors), colored on second sides (Low-E glass outside).In order to prevent the broken glass debris, doubling down side must. Because qualified laminated glass is not damaged when the debris generated, is still able to maintain its integrity.
Q:Six meters long, standard 10 channel steel, theoretical weight
Six meters long standard 10# channel steel, theoretical weight is 60kg.Check the table, there are 10# channel steel per meter theoretical weight of 10.007kg/m, so the theoretical weight of 6 meters is: 10.007x6=60kg.
Q:14 of channel steel and 12 of I-beam which force?
The mechanical parameters of 14 channel steel are larger than that of 12, including the moment of inertia, the radius of inertia and the coefficient of cross section. Therefore, the same length of 14 channel steel can bear a greater force.
Q:What about channel 16?
Waist height of 160mm channel (channel number usually take ten is waist high), 160*63*6.5 and 160*65*8.5 two models, respectively, 160a# and 160b#, the general situation is not specified, with a, B that kind of time, usually 160a#.
Q:What machine is used to bend the channel?
Specify the requirements for bending accuracy and whether there is any curvature change requirement. Does this decision require numerical control equipment?.
Q:Where can I find the tensile strength of channel steel
Tensile strength and yield strength are independent of size and size, but only material.
Q:The role of channel?
According to the type of channel steel, different kinds of it have been used widely. The utility model can be used for decoration, outdoor advertisement board support and steel structure room. etc.
Q:Channel bearing capacity
It's important to see where you've used it. If you allow it to bend, you'll have to bear a lot of weight, but vice versa
Q:Does anyone know how to calculate the volume of channel steel?!
Theoretical calculations can be used: sectional area * length. There are sectional sizes in the specifications of channel steel labels. The sectional area and volume shall be calculated first. When measuring the sectional area, the grid paper can be used. Of course, the accuracy is limited.
