Spiral welded steel pipe
Spiral steel pipes are made by steel coil, extrusion forming under the normal temperature, then taken the technology of double wire and double-faced submerged-arc welded.
During molding process of spiral welded steel pipe, steel plate has uniform deformation and light residual stress, thus the surface has no scratches. Spiral steel pipe has more flexible thicknesses and diameters, especially in making high-grade thick pipes with small or medium aperture, these techniques has incomparable advantages in satisfying your needs.

Mild steel Hollow Sections
Rectangular/ Square hollow section manufacturing process
Rectangular/ Square hollow section are formed from coils and then ran through a series of dies. They are are welded from the inside to form their shape.

Galvanized Steel Pipe
Coated in zinc, galvanized steel pipes are protected from oxidation and rust, which ultimately prevents deterioration of the pipe. They are a great option when you need to protect your steel pipes from a corrosive environment. The protective quality of galvanized pipe is created through a hot-dipping process, where the zinc then provides a protective layer that will rust away before any of the steel is affected. In terms of durability, a galvanized steel pipe can last well over 100 years, depending on the amount of corrosion exposure.

304 Stainless Steel Welded Pipe Seamless Piping
The carbon steel seamless steel pipe is made of a whole piece of metal and has no seam on the surface.According to the production method,seamless pipes are divided into hot tube, cold-rolled pipe, cold-drawn pipe, extruded pipe, pipe jacking and so on. The carbon seamless steel pipes are mainly used as drilling pipes for petroleum geology, cracking pipes for petrochemical industry, boiler tubes, bearing pipes and high-precision structural steel pipes for automobiles, tractors and aviation.
