Import and export orders to use commonly required specifications, the steel is carbon steel steel corresponding. That is, in addition to the specification number, there is no specific composition and performance of the series.
Stainless steel flat delivery length. Length, double length two, domestic fixed scale range of choice according to different specifications, there are 3 - 9m, 4 - 12m Japanese length selection for 6 - 15m respectively.
Import and export situation
