How can I choose the correct dimensions of rectangular steel tubes for my project?
The size specifications of rectangular steel pipes can be summarized into two dimensions: outer diameter and wall thickness. Specifically, according to the size of the outer diameter, it can be divided into three types.
The first type is a super large rectangular steel pipe, with an outer diameter of AXB greater than 400 square millimeters and a wall thickness of 6mm ^~25mm;
The second type is large rectangular steel pipes, with an outer diameter of AXB between 100 ^ 400 square millimeters and a thickness of 6mm ^~14mm;
The third type is small rectangular steel pipes, which have an outer diameter of AXB less than or equal to 100 square millimeters and a thickness of 0 5mm ^~6mm.
For specially made rectangular steel pipes, according to processing and usage requirements, the outer diameter can be customized to 10-800 square millimeters, such as sizes within 0.5-20m. In the specification design, it is necessary to ensure that the strength of the rectangular steel pipe meets the requirements, adopt a reasonable shape, reduce material consumption and weight, and consider the existing production capacity to continuously improve the process and reduce production costs.
In addition, in order to reduce the supply cost of specific size specifications for rectangular steel pipes, rectangular steel pipe brands will adopt a compromise plan based on technical and economic considerations of "production capacity", "meeting market demand", and "setting prices" to determine the optimal size specifications for rectangular steel pipes.
