On March 28, 2016, one of our loyal client from Vietnam has visited our headquarter (SHINESTAR HOLDINGS GROUP) for negotiating with a new order. Mr. A has became one of PRIME STEEL PIPE's loyal client for seamless steel pipe. This time, Mr. A flight to China along with a new order for SSAW Steel Pipes, and PRIME STEEL PIPE is the only superior supplier for him. SHINESTAR HOLDING GROUP has invested many production lines for steel pipes, while the production line for spiral welded pipe is the first invested. We know spiral welded steel pipe more than other suppliers in China. SSAW Steel Pipe (spiral submerged arc welded steel pipe) is the most widely steel pipes applied for general structure and structural support due to its low production cost and better strength than other welded pipe.
