The difference between galvanized rectangular tube and galvanized square tube
1.Shape
Galvanized Rectangular Tube: Has a rectangular cross-section with different lengths of long and short sides, usually used in structures that require a larger load-bearing capacity.
Galvanized square tube: It has a square cross-section with four sides of equal length, suitable for applications with high symmetry requirements.
2.Size
Galvanized rectangular tube: The external dimensions can be customized as needed, and the aspect ratio can be changed to suit different engineering requirements.
Galvanized square tube: The overall dimensions are usually uniform, and common specifications include 20mm x 20mm, 30mm x 30mm, etc., which are suitable for standardized applications.
3.Application
Galvanized rectangular tube: commonly used in building structures, support frames, fences, machinery manufacturing and other occasions that need to bear large loads.
Galvanized square tube: Widely used in furniture manufacturing, decoration, transportation and other fields because of its beautiful appearance and easy processing.
4.Strength and stiffness
Galvanized Rectangular Tube: Due to its shape, it usually performs better in terms of load-bearing capacity and stiffness and is suitable for use in load-bearing structures.
Galvanized Square Tube: While also offering good strength, in some cases rectangular tubing may provide better support in a particular direction.
5.Manufacturing process
The manufacturing process of the two is similar, usually produced by cold rolling or hot rolling process, and then galvanized, but in the forming process, the molds and processes of rectangular tubes and square tubes may be different.
Comparison of production processes of galvanized rectangular tubes and galvanized square tubes
1.Raw material preparation
Galvanized rectangular tube: Usually use steel strips or steel plates of different widths and thicknesses, which are cut and formed.
Galvanized Square Tube: Use steel strip or steel plate of equal width and thickness, cut into a square shape.
2.Molding process
Galvanized rectangular tube:
After the steel strip is rolled, it forms a rectangular tubular structure, which usually needs to be formed and adjusted several times to ensure that the dimensions of the long and short sides meet the requirements.
Galvanized Square Tube:
After the steel strip is rolled, it forms a square tubular structure. The forming process is relatively simple because the lengths of the four sides are equal.
3.Welding process
The welding process for both is usually similar, using methods such as high frequency welding or arc welding, but when welding, rectangular tubes may require more precise control to ensure the strength and appearance of the welded joint.
4.Cooling and solidification
After welding, both pipes need to cool and solidify, but due to the different shapes, the cooling method and time may be different.
5.Surface treatment
Both Galvanized rectangular tube and Galvanized square tube require cleaning, degreasing and rust removal on the surface, and then galvanizing. The galvanizing method (hot-dip galvanizing or electro-galvanizing) is usually the same, but during the processing, the processing time and method of rectangular tubes and square tubes may be different.
6.Inspection and Testing
During the inspection and testing phase, the standards and requirements for the two pipes may be similar, but due to the different shapes, the specific inspection methods and tools may be different.
Summarize
Although the production process of galvanized rectangular tube and galvanized square tube is similar in many aspects, the specific forming, welding and inspection processes may be different due to their different shapes and sizes. The selection of the appropriate production process should be determined according to the specific requirements and application scenarios of the product.
