    High Quality Low Carbon Pipes And Tubes

    The low carbon steel annealed structure is ferrite and a small amount of pearlite, which has low strength and hardness, and good plasticity and toughness. Therefore, the cold formability is good, and cold forming can be performed by a method such as crimping, bending, or press. This steel has good weldability. Low carbon steel with a very low carbon content has a low hardness and poor machinability, and normalizing treatment can improve the machinability. Due to the inherent characteristics of low carbon steel, the scope of its use has been greatly limited. With the application of some new domestic technologies in the steel industry, many new uses of low carbon steel have been well exploited.

  • Pre Galvanized Steel Tubes 48.3mm

    Pre Galvanized Steel Tubes 48.3mm

    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 galvanized and pre galvanized 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.

  • Welded ERW Steel Pipes For Construction

    Welded ERW Steel Pipes For Construction

    ERW welded steel pipe is a steel pipe made by electric resistance welding after being formed by crimping a steel plate or a steel strip. ERW stands for resistance welding, which has the characteristics of high production efficiency, low cost, material saving and easy automation. ERW welded pipe is one of the most common pipe materials. Because of its durability and corrosion resistance, it is widely used in aviation, energy, automotive, and light industries. ERW welded pipes are also often used as structural pipes. Resistance welding is one of the most important welding methods.

  • En74 Fixed Clamp And Couplers For Scaffolding Tubes

    En74 Fixed Clamp And Couplers For Scaffolding Tubes

    Scaffold couplers are the fundamental component that is used together with scaffold tubs. The scaffolding tubes are joined together by steel clamps and couplers, and the scaffolding tubes work as the standards, braces and ties for workers to do the construction work in height. There are various types of clamps and couplers. Japanese, British, and German type clamps. Based on different producing process, the fittings are included into pressed and drop forged couplers. For British couplers, the common standard is EN74 and BS1139. The surface treatment is Electro galvanized, hot dipped galvanized and painted, while the electro galvanized is the better choice because of the beautiful surface and lower cost.

  • Hollow Sections EN 10210 Standard Tubes

    Hollow Sections EN 10210 Standard Tubes

    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.

  • Scaffolding Steel Props For Formwork

    Scaffolding Steel Props For Formwork

    Scaffolding Steel Props for Formwork Scaffolding Steel Props are frequently used in formwork and construction to support the floors, ceilings, bridges and beams. With its high load-bearing capacity, it is popular on temporary supports during building repair or alteration work. The advantages are easy to use and time-effective to install, also lower cost. In construction, steel props is used as vertical support in scaffolding as below situation, such as: removing walls, making holes, temporary support for ceiling, beams and so on.

  • Electrol Galvanized Scaffolding Steel Props

    Electrol Galvanized Scaffolding Steel Props

    Steel prop is frequently used in formwork and construction to support the floors, ceilings, bridges and beams. With its high load-bearing capacity, it is popular on temporary supports during building repair or alteration work. The advantages are easy to use and time-effective to install, also lower cost. Then how to test the quality of steel props when you purchase the products. Firstly, the raw material of the steel tubes. There are various steel coils for tubes such as Q195, Q235 and Q345 with different mechanical performance. Secondly, the welding parts is significant. The welding lines should be smooth and totally melt with the plate. It’s important to check the welding lines in case of incomplete welding and air holes. Thirdly is the surface. Painted, galvanized, powder coated surface are available. Painting is easy to fall off after cracking while the galvanized ones are better on anti-rusting. Powder coated surface is much better than painted, but the cost is much higher.

  • 210 Mm GI Plank For Scaffolding

    210 Mm GI Plank For Scaffolding

    210 mm GI Plank for Scaffolding 210 mm GI Plank for Scaffoldings are frequently used in scaffolding acess platform and construction area, which is convenient for workers to walk through on it by providing strong support during usage. It is a fitting part of scaffolding, commonly be used together with scaffold tube, steel frame and ringlock systems. There are different types for etal steel planks, with hooks or without hooks. Its advantages are fire resistance, higher capacity , and uneasy to get rusted. The GI Plank for Scaffolding are popular among Southeast Asia, Mideast markets. Usually the surface are pre galvanized, with the zinc coating preventing the rusting during usage. The raw material is Q235 steel with strong capacity, which can be used for 5-8 years.
