For example, the actual card of the hot-rolled plate may only be 12 thick in the national standard, which is also in line with the national standard, therefore, you can't say that there is a shortage of catties or two.

Ask the manufacturer to use a small electronic scale, which is a kind of weighing scale directly hung on the crane, five tons. Our factory uses that kind of pound, each piece of steel is weighed separately, and there is no customer to report the problem of short scale.

The pound difference is really a headache The pound difference on our side is the business to pay for the customer, and at present, it is generally in accordance with the third-party pound in the market, and the pound difference is half of one person.

Generally, the weight is more out and less in, and the normal weight difference in our company is 3/1000. I don't know how much you** are.

Haha, it's definitely cheaper than the market, of course this kind of problem will exist!
