Applications of UPN Channel Steel:

The UPN Channel Steel can be applied to construction of warehouses, workshops, sport stadiums and car parks etc.The hot rolled channel steel belongs to carbon structural steel which is applied to in the field of construction and machinery.In details, the hot rolled channel steel 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. Generally,the hot rolled channel steel we supply must possess perfect welding property, riveting property and mechanical property and so on.

Q:How can channel A and B be distinguished?
Of the same height, type B has wider legs and thicker waist than A.
Q:What does channel steel look like? Where is it usually used?
Channel steel is a kind of U steel, which is useful as stated. They are usually used in steel structures.
Q:How many meters per ton is channel ten?
Channel ten, one ton, about 468 meters. Specific architectural manuals can be examined.Channel steel: the channel steel is a long strip steel with a cross section. Its specification means: such as 120*53*5, which means that the waist height is 120 millimeters, the width of the leg is 53 millimeters of channel, the waist is 5 mm thick channel, or called 12# 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 25a#, 25b#, 25c# and so on.
Q:What is the maximum load-bearing capacity of channel 12M span 100?
When flat, the span of one meter is concentrated, and the solution is as follows: M=W[,]=15610*215=3356150N-mm=3.356kN-mM=L/4*N+q*L*L/8N= (M-0.1*1*1/8), *4= (3.356-0.1*1*1/8), *4=13.374kN (1.3 tons)When standing, the span of one meter is concentrated, and the solution is as follows: M=W[,]=39660*215=8526900N-mm=8.527kN-mM=L/4*N+q*L*L/8N= (M-0.1*1*1/8), *4= (8.527-0.1*1*1/8), *4=34.058kN (3.4 tons)
Q:What is the allowable bending strength of Q235 channel steel? Why does the mechanical manual have no bending strength?
Q235 channel design value of general 215N/mm^2, such as thin-walled steel pipe design values, such as 205N/mm^2.
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: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.
Q:How much is the load-bearing capacity of No. 10 I-beam per metre?
National Standard No. 10 I-beam is 11.261kg/ meters; 6 meters long weight is 67.566kg
Q:Galvanized steel plate, channel steel, angle steel how to take samples, how to submit?
Each batch of 60t of the same raw material, the same batch number, the same grade, the same variety, the same size and the same delivery status is used as a batch. Sampling requirements: symmetry type steel (such as steel, T steel), in the distance where the interception endpoint 1/6 length long 500 mm, 20 mm wide rectangular healthy specimens, non symmetry type steel (such as steel, L steel), in the distance where the endpoint 1/3 length of 500 interception mm, 20 mm wide rectangular specimens. Direct interception of local plate in from the outer ends of the 12.5 mm long 500 mm, 20 mm wide rectangular specimens. Take one for tensile test and one for cold bending test.
Q:What is the weight of the national standard 8# channel steel?
The theoretical weight of national standard 8# channel steel is 8.045 kg / m.
