Applications of GB Standard Hot Rolled Steel U Channels for Constrction:

1.Character: The Structure Steel U Channel belongs to carbon structural steel which is applied to in the field of construction and machinery.

2.The structure steel u channel is usually used for architectural structure, and they could be welded in order to support or hang a variety of facilities. They are usually used in combination with I beam.

3.Generally, the structure steel u channel must possess perfect welding property,riveting property as well as mechanical property.


Package & Delivery of GB Standard Hot Rolled Steel U Channels for Constrction:

The structure steel u 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.

And structure steel u channel could be loaded into 20ft or 40ft container, or by bulk cargo.If the weight of each bundle reaches less 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.

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

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

Q:How about the Y-Y moment of inertia in the form of hot rolled channel steel Iy?
Moment of inertia (Ix or Iy) = area X the square of the centroid to the axisRadius of inertia (IX or iy) = the area divided by the moment of inertia, then taking rootInertial product (Ixy = area multiplied by centroid to two axis distance)Coefficient of flexural cross section (Wx or Wy) = moment of inertia divided by the distance from the farthest point of the coordinate axis on the cross section
Q:Channel steel, I-steel, round bar, angle steel, Fang Gang price is per ton to count or by rice? How about tons and meters? The formula is best
Base area * * 7.85 (7.85 is the specific weight of steel)If the unit of computation is mm, it is "gram""If the unit of work is centimeter, it is "kilogram""If the unit of measurement is rice, it is ton"
Q:Span 3.9. Can I make attic with channel No. 10?
Channel 10 is a little small, at least with 12# channel steel.
Q:Larry Midas in seeking to inform how to model such as: steel, double steel, double channel
If civil is set in the channel, double cross section library inside, Larry is through the section properties of I-steel calculator, drawing DXF graphics in CAD, import
Q:What is the difference between steel tubes such as channel steel or square tube?
Channel steel is divided into ordinary channel steel and light channel steel. Standard Specification for hot-rolled plain channel steel is 5-40#. Specifications for hot rolled flexible channel steel supplied by supply and demand agreement are 6.5-30#. Channel steel is mainly used for building structures, vehicle manufacturing, other industrial structures and fixed plates, cabinets, etc., and channel steel is often used in conjunction with i-beam.
Q:10# how much is it per kilogram of channel steel?
Cold rolling edge channel (CJ/YB99-81 standard standard)The height of =120, legs wide =60, short width =20, thickness =3, leg end arc radius =3.0, cross-sectional area (cm2) =7.808, (kg/m) =6.090 theoretical weight (legs bent inward kind)If the non target is not necessarily.
Q:What is the wall thickness of national standard 8* channel steel?
8# channel steel GB wall thickness should be 5.0mm (mm),
Q:Is the channel 20 the same as the channel 20b?
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.
Q:How to choose angle steel and channel steel for dry hanging stone?
The specifications of the metal frame used for hanging stone are mainly the thickness of the stone and the strength of the wall!
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.
