Hollow Carbon Steel Tubing , Construction Galvanized Steel Pipe STK500
The stk500 is one of structural steel pipes and one of the steel materials for civil engineering and construction. Although it is a low-carbon type, since the tensile strength is also minimum and the strength is guaranteed to be 500 mPa or more, a method different from the so-called material pipe can be used.
Application
STK steel pipe is the general structure of carbon steel pipe, but also as a structural carbon steel pipe. Applications are used in addition to buildings. However, the main purpose envisaged is the provision of strength with respect to pillars and feet, landslide suppression columns, foundation pillars, towers and other buildings. Welded steel pipes with an outside diameter of 318.5 mm for base rods. In the case of landslide suppression, the joints of the same size have no pipe or welded pipe.
