Hollow Carbon Steel Tubing , Construction Galvanized Steel Pipe
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.
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.
