Q195 is mainly used in which parts of buildings?
Mainly used in non-load-bearing/light-load structural components, such as light steel keel, purlins, wall beams, scaffolding, ceiling supports, door and window frames, decorative panels, etc.
12. Can Q195 be used as a main load-bearing component of a building?
No, its yield strength is only 195MPa, which is insufficient to meet the load-bearing requirements of beams, columns, load-bearing walls, etc.
13. Can Q195 be used to make reinforcing bars?
Not suitable as a main reinforcing bar. It can only be used to make cold-drawn low-carbon steel wire, steel mesh, stirrups, and other non-primary load-bearing reinforcing steel components.
14. What are the applications of Q195 in steel structures?
Secondary components of light steel structures, such as roof purlins, wall beams, support systems, enclosure structure skeletons, as well as steel structure connectors and supports.
15. When is Q195 used for building pipelines?
It can be used to manufacture welded pipes for low-pressure fluid transportation (water and gas pipes, electrical conduits), but it is strictly prohibited for use in high-pressure, flammable and explosive fluid transportation.
