Strength grade standard for precision rolled threaded steel
PSB830/PSB930/PSB1080/PSB1200
Precision rolled threaded steel bars can be roughly classified into the following three aspects: application field, geometric shape, material, and specifications.
According to the application field, it can be divided into five categories:
1. Precision rolled threaded steel bars for non-destructive testing of buildings: mainly used for durability testing and structural non-destructive testing of buildings.
2. Precision rolled threaded steel bars for geotechnical engineering monitoring: mainly used for on-site inspection of dams, tunnels, landslides, and geotechnical engineering tests.
3. Advanced precision rolled threaded steel bars: mainly used for evaluating the structural characteristics of materials such as coatings, pipelines, metals, and plates.
Classify according to geometric shape, that is, classify according to the cross-sectional shape of the ribs and the different spacing of the ribs.
