hot-rolled seamless steel pipe and a cold-rolled seamless steel pipe
Cold-rolled seamless steel pipes are often of small diameter, and hot-rolled seamless steel pipes are often of large diameter. The accuracy of cold-rolled seamless steel pipe is higher than that of hot-rolled seamless steel pipe, and the price is also higher than that of hot-rolled seamless steel...Read more -
difference between pre-galvanized steel tube and hot-galvanized steel tube
Hot dip galvanized pipe is the natural black steel tube after manufacturing immersed in the plating solution. The thickness of the zinc coating is affected by a number of factors, including the surface of the steel, the time it takes to immerse the steel in the bath, the composition of the steel,...Read more
