Galvanized Scaffolding Tube, Weld Scaffolding Pipe, Steel

As advanced and professional tube scaffold manufacturer in China EK offers hot-dip galvanized scaffolding pipe with 48.3*3.0/3.2/3.8/4.0mm sizes to choose. Welding scaffold tube manufactured with standard Q235/Q345 carbon steel. The surface treatment of this scaffolding tube is also hot dip galvanized guaranteed. Grade Q345 Imported Tube does not conform to grade S355 Hardness before forming Q345 was 80 Rockwell B, similar to the locally supplied tube, but when drawn down it increased to 97 while the locally supplied steel increased to only 90. This indicates that the Q345 becomes a much harder material when manipulated if compared to locally manufactured tube. Carbon steel square tube - qiyuangtchinaOct 27, 2020 · Precision steel pipe is a kind of high precision steel pipe material after cold drawing or hot rolling.Because the inner and outer wall of the precision steel tube has no oxide layer, no leakage under high pressure, high precision, high finish, cold bending without deformation, flaring, flattening without cracks and other advantages, it is mainly used for the production of pneumatic or Q345R Pressure Vessel Steel Plate for Boiler ManufactureQ345 Pressure Vessel Steel Plate Q345R is common low alloy steel, it is the boiler pressure vessel commonly used steel type, the delivery state:hot rolled or normalization.
