The carbon steel seamless steel pipe is made of a whole piece of metal and has no seam on the surface.

SSAW, short for Spirally Submerged Arc Welding, means spirally submerged arc welding pipe, SSAW steel pipe is spirally submerged arc welding, also known as spiral steel pipe.
Mainly used for oil and natural gas pipelines, its specifications are expressed by outer diameter * wall thickness.

Structural Steel Tubing is cold formed from coiled sheet steel and electric welded into square and rectangular shapes. Made to minimum mechanical properties it is excellent for structural applications requiring welding and some mild forming.Applications include automotive equipment, tables, and racking. Construction applications such as bridges, buildings, and agricultural machinery.

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength, such as fixture clamps, mounting plates, and spacers. This material can be surface hardened with heat treating.

These steel sections are rolled from steel sheet or slit coil. The slit strip of steel coil goes through a forming and sizing section in a normal cold forming steel mill. The mill consists of a number of passes through which the sheet is gradually formed, each pass bending the steel sheet more and changing the radii on each pass. This is done until the two ends of the steel is pressed together and then welded inline.Round steel sections can be rolled from a variety of materials. Most common is hot and cold rolled steel tubes. Hot rolled sections are predominantly used for structural purposes while tubes rolled from cold rolled steel has better bending ability and gives a better aesthetic appearance after being powder coated.

Carbon mild steel round tubing is used in most general purpose applications. Low carbon content relatively good mechanical properties along with high quality weldability make it a common choice in fabrication and structural applications. Easily drilled, welded and formed. Uses include: general machinery where suface imperfections may be tolerated.

The main uses of carbon steel square tube products are: construction, machinery manufacturing, steel construction and other projects, shipbuilding, solar power generation brackets, steel structure engineering, power engineering, power plants, glass curtain walls, etc.

The carbon steel seamless steel pipe is made of a whole piece of metal and has no seam on the surface.Mainly used in instrumentation, automobile, aerospace, bridge construction, machinery manufacturing, chemical industry, casting, engineering construction, steel structure construction and other industries.
