How about quality requirements for JIS SM400A plates

We have 4 typical production lines, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. SSAW pipe production line range is OD 219.1mm-3500mm, wall thickness 3.2mm-25.4mm. Product JIS SM400A plates annual capacity is 200 thousand tons.

At present, the overall market demand of JIS SM400A plates is weak, the purchase intention of end users is not strong, and the purchase is basically on demand. The market transaction of JIS SM400A plates is relatively general, and some markets have declined. However, the overall market inventory of JIS SM400A plates is not high, coupled with the strong willingness of steel mills to support price, and the high resource cost in the later stage, therefore, businesses are not willing to sell of JIS SM400A plates at too low price. On the whole, the short-term market of JIS SM400A plates is expected to be dominated by high fluctuations.
