Electrician pure iron ① its stainless steel grades Tai'an fine screw letters "DT" and numbers, "DT" indicates electrician indicates the sequence number of different grades of stainless steel fine screw Zibo iron, digital, such as DT3. ② in the later letters plus numbers electromagnetic properties: A-- advanced, E-- premium, C-- super, such as DT8A. 3 length dimension editor steel length dimension is the most basic dimensions of the various steel refers to steel length, width, height, diameter, radius, diameter, outside diameter and wall thickness of equal length.

When you press multiple length delivery, the length of the metal material must be specified in the contract for the demand side length delivery (called haplotypes feet) of integer multiples (plus kerf). For example, the demand side in the contract single double length of 2m, then cut the length of time that is 4m Qingdao double foot stainless steel fine screw, is 6m, plus cut three times when one or both feet respectively kerf amount. Jukou amount of provisions in the standard. When the double length delivery, allowing only a positive bias, negative bias value allowed.
