Product Applications:

1.The JIS channel 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 JIS 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.

Production Flow of JIS 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 channel should be put onto the cooling bed to make the temperature low.

4. The JIS 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.

 

Package & Delivery of JIS Channel:

1.The JIS 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.

2. And the JIS channel 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.

- Inquire about price/MOQ

Q:Which is cheaper, the same size, ordinary channel steel and light channel steel? Price difference is not big?
If the cost per meter, of course, is light and cheap.The specific gap, you can also refer to the hardware manual, the two are compared. Because of the tonnage, the prices are almost the same.
Q:Is it OK to use the channel steel to do the Overhanging Scaffold? Is there any difference between the cantilever scaffold made of I-beam and channel steel?
Yes, both I-beam and channel steel have specifications and models. As long as they can meet the load requirements, there is no difference between them.
Q:How much is the channel steel? How much is one and how long is it?. What is the price of different sizes?
This is too difficult for you to answer, for example: 10# channel steel, the worst wide 10mm, width 5MM, material thickness of about 5MM, the price of about 95 yuan. The national standard is about 150 yuan.
Q:What does channel specification "MQ-41" mean?
The raw material for producing channel steel is carbon or low alloy steel billets with a carbon content of not more than 0.25%. The finished channel steel is delivered by hot forming, normalizing or hot rolling. The specifications are expressed in millimeters of height (H) * leg width (b) * waist thickness (d), such as 100*48*5.3, which means waist height is 100 mm, leg width is 48 mm, waist thickness is 5.3 mm channel, or 10# channel steel. The same height of the channel, if there are several different leg width and waist thickness, also need to add a, B, C on the right side of the model to distinguish, such as 25#a, 25#b, 25#c and so on.
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:What does "deformed L/200" mean in the carrying capacity of channel steel?
Most of the traditional bridge deflection measurement using a dial gauge or displacement gauge measurement, the current safety assessment in the old bridge or bridge acceptance is still widely used in China, the maintenance of the bridge. The advantage of this method is that the equipment is simple and can be used for multi-point detection. The deflection values of each measuring point are obtained directly, and the measurement results are stable and reliable. But the direct measurement method has many deficiencies, the method requires measuring point pull wire or erection shelf at all, to be measured directly with water under the bridge so; to overpass, affected by railway or highway traffic bound, the method can also be used; across the canyon and other Takahashi also cannot use the direct method of measurement in addition to using direct method; deflection measurement, regardless of layout or revoke the instrument, are relatively complicated time-consuming.
Q:How do you calculate the weight of 100 channel steel?
CAD drawing can also be used to calculate the cross-sectional area of 100 channel, or other ways to first calculate the cross section area of 100 channel.
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?
The stability of channel steel can not be checked, and the flexural strength of channel steel is checked only. The following bending moment diagram can be obtained by calculation8 =Mmax/ (gamma Wx) +N/A=1875N - m/ (1.05*39.7cm - <[f]=205N/mm - +0/12.74=45N/mm fand), to meet the requirements.The Mmax in the upper form is derived from the diagram, and is computed by itself as 1875N, m=1875000N, mm;Gamma cross-section plastic development coefficient, 1.05;Wx No. 10 steel section modulus, look-up table, Wx=39.7cm =39.700mm fand fand;N steel axial force, 0;A channel section area, look-up table, A=12.74cm L.
Q:16A channel steel size requirements are national standards Oh!
The national standard for channel steels is "hot rolled steel" GB/T706-2008
Q:What's the weight of the 4 meter long 18 channel steel?
Channel steel is a strip of steel with a cross section. Section steel with groove shape. 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.. In use, it requires better welding, riveting performance and comprehensive mechanical properties. The raw material steel billet for channel steel is carbon or low alloy steel billets with a carbon content of not more than 0.25%. The finished channel steel is delivered by hot forming, normalizing or hot rolling. The specifications are expressed in millimeters of height (H) * leg width (b) * waist thickness (d), such as 100*48*5.3, which means waist height is 100 mm, leg width is 48 mm, waist thickness is 5.3 mm channel, or 10# channel steel. The same height of the channel, if there are several different leg width and waist thickness, also need to add a, B, C on the right side of the model to distinguish, such as 25#a, 25#b, 25#c and so on.
