Usage of JIS Standard Hot Rolled Steel U Channels for Constrction:

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.



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.

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



Production Flow of JIS Standard Hot Rolled Steel U Channels for Constrction:

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.

Q:British standard I-beam 203*203*46 size
The main specifications of the available contour I-beam section size (mm) expressed in high waist leg width (H) * (b) * (d) mm thick waist numbers, such as I160 x 88 x 6, namely said waist height 160mm, waist leg width 88mm, thickness 6mm i-beam. I-steel specifications are available models (Tex) said, showing the type of waist high number of centimeters, such as waist high 160mm I-beam type I 16#. The same as the waist high beam, there are several different leg width and waist thick, need to add code in the model (also known as the right corner) a or B or C to make a difference, such as 32a#, 32b#, 32c# etc..
Q:What is the difference between steel tubes such as channel steel or square tube?
The channel for supporting, steel used for machining shaft and pin and the like, used to make steel keel frame and embedded parts in civil engineering, steel used for heavy support for small angle support or molding square tube used for various doors and windows, modification.
Q:What is the standard for channel steel execution?
Standard for channel steel GB707-88
Q:According to the standard? indoor hanging stone 30 meters high? whether to add channel?
The most necessary to use the channel skeleton, hanging directly on the wall is not safe
Q:Channel 10 is calculated, if the price per metre is calculated
On the market, the sale of 10 channel steel, a lot less than the national standard weight, the general negative difference in 5% within the standard. Depending on your use requirements, the maximum negative difference may be as high as 30%.
Q:How can channel A and B be distinguished?
In general, B is thicker than a and 2mm thick.
Q:Reasons for opening holes on channel steel
This machine is in stainless steel and flat iron, steel, steel, iron processing market are welcome and certainly very warm. Compared with traditional hand press and bench drill, have greatly breakthrough both in structure and performance. High speed hydraulic anti-theft net punching machine one day can punch 400-500 square security net, is currently the stainless steel tube and flat iron, flat steel, channel steel, angle iron punching processing fast equipment. The machine can be customized to a number of working positions, with simple disassembly, simple mold, durable, novice easy to use and so on. Die with the scale, convenient direct reading, free debugging red half hole or hole punched, smooth without burr, accurate positioning, can produce a variety of new anti-theft network (diamond anti-theft network, anti-theft network, plum garden square tube anti-theft network, can make door flower, guardrail, shelves, flat iron, steel, the channel, etc.) the use of punching angle. Is the most ideal processing equipment of stainless steel and flat iron, steel, steel, iron pipes and other processing households, profile processing businesses.
Q:What is the difference between C steel, U steel and channel steel?
U type steel (hot rolled U steel mine roadway Name: U steel) is English steel like the letter "U" with a cross section, sometimes with a cross section of Japanese letters "better" shape. Main features: large pressure, long support time, easy installation, not easy to deformation and so on. Main uses: mainly used in mine roadway, roadway support, and two times of the tunnel supporting etc.. As the main shape steel for the retractable metal support of tunnel, U steel is widely used at home and abroad.
Q:Is channel steel expensive or angle expensive?
If the loading requirement is not high, then use the angle iron is good, with angle steel to save money, channel steel beam ah, what is more. Relatively high bearing capacity. Landlord mainly in the right place, with the right products, the most economical, and rely on live.
Q:Cautions for surface zinc spraying on channel steel
Thermal spraying principle summary is the first use of high pressure air pipe and the sand blown to the surface of the metal workpiece surface to remove rust and oxide skin on the surface, at the same time by increasing the absorption for Ma thermal spray coating, and then use oxygen, acetylene or electric heat source (large workpieces with electric heating, and the type of oxygen and acetylene by heating) compressed air and special tools (gun) to ultra high speed jet atomization of zinc to the metal surface.
