The following is an introduction to these various shaped tubing materials:
I. 9090 Octagonal Tube & 8787八角管
Dimensional Features：
9090 Octagonal Tube with Edge Length of 90, 8787 Octagonal tubes have an edge length of 87. Both are octagonal in shape, featuring unique appearance and geometric characteristics.
Larger dimensions make them suitable for applications requiring greater structural strength and stability.
Application Scenario：
In the construction field, suitable for making large decorative columns, railings, etc., adding a unique style to buildings.
In the industrial sector, it can serve as a supporting component for framework structures or conveyance pipelines, bearing certain weights and pressures.
Performance Advantages：
The octagonal shape offers better stability and torsional resistance, making it less prone to deformation under external forces compared to other shaped tubing.
Weldable and bolted connections available for easy assembly with other components.
2. 70*70 Hexagonal Tube
Size characteristicsHexagonal shaped tubing with a side length of 70, moderately sized.
Application Range：
Commonly used in mechanical manufacturing and furniture production. For instance, it can serve as the supporting structure for mechanical parts or the frame components for furniture.
In some decorative projects, hexagonal tubes can also serve as unique design elements, adding a sense of three-dimensionality and artistry to the space.
Performance Advantages：
The hexagonal shape offers good stability and strength, capable of withstanding certain external forces.
Hexagonal tubes are easier to handle in terms of connection and fixation compared to round tubes, as welding or bolt connections can be made through the corners.
