Q:Does anyone know how to calculate the volume of channel steel?
Experimental method can be used: if the volume is small and convenient, the "channel" will be integrated into the tank filled with water measurement. Get ready A: a pool full of water. B: an estimate of the amount of water that will be discharged when a channel is placed in a tank full of water. C: put the "channel" into the water tank and load the water discharged by the container. D: the volume of water discharged from the metering unit. That is equal to the volume of the channel. Other liquids that do not destroy channel steel can also be used
Q:In the construction engineering construction site, such as channel material piled reinforced why mat wood, directly on the concrete floor (ground) on the surface is not?
Steel and other raw materials must be on the lower cover, this is mainly to prevent rust, the owners site civilized construction inspection itemsIf you don't pad things, they are found to be penalized or fined
Q:12# how much is a channel steel? The length is 6 meters. GB steel channel should be used
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:I would like to ask about the supporting strength of channel steel!
This is the main push rod stability problem, the strength of individual words feel no need to calculate, the compressive strength of steel are great, you can also check the tensile strength of 304 stainless steel is 205MPa, the compressive strength will certainly be much higher.
Q:10kV and below the distribution cabinet in the room, the basic channel should be higher than the indoor ground level? Which specification is clearly defined?
The distribution cabinet is used in occasions where the load is more dispersed and the circuit is less. The motor control center is used in the situation where the load is concentrated and the circuit is more. They distribute the power of a circuit to the nearest load. This class of equipment provides protection, monitoring and control of loads.
Q:What kind of welding rod used for channel steel?
Manual arc welding, the use of strength grades T50 electrode: knot 506, knot 507, knot 502, knot 503, knot 552, knot 553, etc.;
Q:Rusting of Q235 steel plate and Q235 channel steel
It shouldn't be a problem. See the GBT 19879-2005_ steel plate for the building structure6.5 surface qualityNo cracks, bubbles, scars, folds, inclusions, and iron oxide sheets are allowed on the surface of the 6.5.1 steel sheet. Steel plate shall not be layeredThe surface of 6.5.2 steel plate is allowed not interfere with the inspection of surface defects of thin oxide scale, rust, pressure by iron oxide shedding caused no significant surface roughness, scratch, indentation and other local defects, but its depth not greater than half of the tolerance of thickness, and should ensure that the minimum thickness of steel plate.
Q:120*53*5.5 what's the weight of channel steel?
120 * 53 * 5.5 12 # 12.06kg/m
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:In the steel structure of steel purlin 160*60*20*2.5 is what mean?
Stands for 160mm height, 60mm width, and 2.5mm thickness, and 20mm is the size of two small ears.
