Steel hollow section can be mainly divided into round hollow section, rectangular hollow section and square hollow section. Rectangular and square carbon steel tube are widely used in various fields such as construction or building, low pressure liquid delivery, engineering, fencing,greenhouse etc.Surface of steel tube generally are black or galvanized, galvanized Steel tube has good features of corrosion resistance, anti-rust, acid resistance, which largely extend its service life.

The GI pipes, also called pre galvanized steel pipes, are cold rolled round pipes made by galvanized steel strips. The GI pipes are widely used in scaffolding construction, greenhouse pipes, fence pipes, agricultural pipes and other areas. There are two kinds of galvanization: hot dipped galvanization and pre galvanization. Pre galvanization is also declined to hot dipped galvanization, which the zinc coating formed by immersing steel pipes into the melting zinc. The difference between hot dipped galvanization and pre galvanization pipes is that pre galvanized pipes are made by galvanized steel coils directly. While hot dipped galvanized pipes are made by black steel coils into black pipes at first, then immerse the black pipes into zinc pond. Tianjin Friend Steel Pipe CO.LTD has more than 15 years experience in steel pipe, we have always tried our best to provide high quality pipes for you.

ERW pipes is a straight seam electric resistance welding pipes, using hot-rolled steel coil as raw material, the wall thickness can be controlled at +/-0.2mm, the pipe end can be grooved, and the length can be delivered. ERW PIPES has been widely used as a major pipe for urban pipe networks by various natural gas pipeline networks and gas companies. As a professional steel pipe manufacturer, we have passed ISO9001 certification. After 15 years of export experience, our steel pipes are sold all over the world. Please believe that our ERW steel pipes have high quality to meet your needs.

ERW is the abbreviation of electric resistance welding. ERW mild stee tube is relatively low in price and widely used.It is a welded steel pipe commonly used to conveying low pressure fluids such as water, gas, air, oil, heating steam and other purposes. ERW mild steel pipe is also widely used as the original tube of galvanized welded steel pipe, with a galvanizing capacity of over 210g/m2 and excellent corrosion resistance. Our factory have lage inventory, can quickly deliver for you.

Welded steel pipes are the most commonly used pipe materials. The welded steel pipe has low cost, high production efficiency and high strength. There are many varieties and specifications of welded steel pipes, of which Q235 is a common steel grade. Q235 is similar to A283 GR.B, 080A15, CS type B. Welding methods for welded steel pipes are ERW, SSAW, LSAW.

TFCO offers structural steel pipes of various sizes to meet structural piping requirements in the water, oil and gas industries.
