Carbon steel square tubes are square tubes made of carbon steel and are a type of carbon steel pipe. Carbon steel pipes refer to steel tubes made of carbon steel materials, and carbon steel square tubes are a specific shape of this type of steel tube, that is, a steel tube with a square cross-section.
Carbon steel square tubes are made by straightening carbon steel plates through a flattening machine and then welding them into shape. The models and sizes of carbon steel square tubes are generally classified and marked according to international standards or national standards.
Types of carbon steel square tubes
Carbon steel square tubes can be divided into hot-rolled square tubes, cold-rolled square tubes, welded square tubes, seamless square tubes and other types according to different uses and processing techniques. The following is a table of common carbon steel square tube types:
1. Hot-rolled square tubes
The carbon steel plate is heated to a high temperature and rolled into shape.
2. Cold-rolled square tubes
The carbon steel plate is rolled into shape at room temperature.
3. Welded square tube
The carbon steel plate is processed into a welded pipe by a flattening machine, shearing machine and other processing equipment.
4. Seamless square tube
It is processed and formed by seamless steel pipe processing equipment.
