With the development of society and users a higher level of engineering quality requirements, the traditional screws in large quantities to be replaced by a new sealing screws. We know that the general is a piece of conventional screw-type structure, although physical good ductility, sealing the screw factory site in Nanjing, not prone to physical changes, and chemical stability, but also makes most of the traditional screw The reaction will not easily happen with chemicals which can affect their performance, but this tends to cause some structure in the construction process vulnerable to external forces and direct fracture. Therefore, Nanjing sealing screw manufacturers, in order to better utilize a large number of scientists. Their structures were regrouping, the emergence of a new three-stage structure of the market in the near future, Nanjing sealing screw factory outlets, also called the new three-zone screw. Weight sealing screw how to calculate it? Our sales staff is necessary to do the basics, offer normal sealing screw including product prices and freight prices sealing screw including screw price plus processing fees, the sale of seal screw when we usually go logistics companies and charged logistics companies are by weight and distance to be calculated. The same weight of the product is the same, but the proximity of the road will cause the total price disparity on the large objects for reasons which the buyer is to compare freight. So freight calculations involved sealing screw weight, the weight includes the weight of the screw seal screw and sealing sheet positioning sheet sealing the screw factory in Nanjing, our manufacturer in order to facilitate business and we will give a general theory of value, such as GB 12 screw 0.888 kg / m, the screw 14 GB of 1.20932 kg / m, when the offer will be calculated in a general freight, when the logistics over there an actual weighing value to buyers generally do not have much to The error, we can accept.
