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:The following steel is not section bar, is it? A. thread steel, B. steel pipe, C. track, D. channel steel
The thread steel belongs to the small section steel, the track and the channel steel belong to the large section steel.According to the shape of the cross-section, the steel is generally divided into profiles, plates, pipes and metal products in four categories.Therefore, the steel pipe belongs to the pipe, not the profile.
Q:Surface area of channel steel
20A channel steel international size is 200*73*7, 1 meters of channel steel surface area is 0.678 square meters, not counting ends
Q:British standard I-beam 203*203*46 size
I-beam is mainly divided into ordinary I-beam, light I-beam and H steel three.Ordinary I-beam, light I-beam flange is variable cross-section, depending on the thickness of the web, the external thin; H steel: HW, HM, HN, HEA, HEB, HEM and so on, the flange of I-beam is a uniform sectionOrdinary I-beam, lightweight I-beam has formed the national standard, the common 10# I-beam is equivalent to the Internet I100 (such as 10# also channel equivalent channel (U100) for the implementation of the standards of different countries, which have subtle differences in their specifications)
Q:How can theoretical weight be obtained for 12.5 channel steel?
12.6# the weight of channel steel is 12.318 kilograms per metre.
Q:8# what's the size of the channel steel?
8# channel steel size 80*43*5mm, that is, height 80mm
Q:Galvanized steel plate, channel steel, angle steel how to take samples, how to submit?
Galvanized steel plate, channel steel, angle steel how to take samples, how to submit?
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:According to the standard, indoor hanging stone 3 meters high, whether to add channel?
The key is to see your wall!! If it's a load-bearing wall. That won't be necessary
Q:28a difference between channel steel and 28b channel steel
50 * 37 * 4.5 5 5.44 #63 * 40 * 4.8 6.3 6.635 #65 * 40 * 4.8 6.5 6.7 #80 * 43 * 5 8 8.045 #100 * 48 * 5.3 10 10.007 #120 * 53 * 5.5 12 12.06 #
Q:What type of channel is used for the type of room with a span of 4 meters?
The flexural strength of 10# steel in the distance is less than 50 cm, a span of 4 meters is safe.
