In structural engineering, the tube is the system where in order to resist lateral loads (wind, seismic, etc.) a building is designed to act like a hollow cylinder, cantilevered perpendicular to the ground. 


The system can be constructed using steel, concrete, or composite construction (the discrete use of both steel and concrete). It can be used for office, apartment and mixed-use buildings. Most buildings in excess of 40 stories constructed since the 1960s are of this structural type.





  

  

For construction, the structure tube is good.

The packing is very strong and make the pipes in good condition.

                                                                                                                                                                    ___Hubery(Turkey)

Logistics is nice, if it can be more fast, it will be better.

Painting with black for free, the service is good.

Pipes used is very well.
