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%.
No. 10 channel steel is calculated, that is to say, the standard weight, that is, all channel sizes have reached the standard, our national standard No. 10 channel steel theoretical weight is 10.007 kg / meter.
When choosing, we can know the gap between the channel and the national standard through weighing. The weight difference is different, the price also has the difference. If calculated, the greater the negative difference, the lower the offer. For example, the current market in Guangxi minus 10% of the 10 steel, according to the theory, the offer is probably 5000 yuan / ton, that is, 50 yuan / meter.
