Features of stainless steel tubes:

1)characters such as Safety, health, environmental protection

2)economy applicable, good surface

3)the resistant to corrosion

4)less weight than bars, thickness and out diameter so variously

5)easy cutting, huge deformation

6)tensile strengthen and good be flexible etc.
