Recently most of the galvanize processing factories in Tangshan City, Hebei Province were cancelled due to the severe air pollution they have done. And it is reported that Tangshan Gov will make a second action to the other rest high-pollution industries at the end of August 2013. It caused the price rise of galvanized steel pipes, especially the hot galvanized pipes. Plenty of galvanizing work went quickly to Tianjin City due to the banning of galvanize processing factories in Tangshan, which made the price of finshed galvanized pipe higher than usual. The worst thing is that many orders signed cannt be fufilled on time.
