Square HSS
Square HSS stands for Square Hollow Structural Section. Its cross section is square and the middle is a hollow steel pipe. Hollow Structural Section has three types of pipes: circular, rectangular and square. What we are going to talk about today is Square Hollow Structural Section.
Square HSS Core Advantages
High strength
Compared to solid pipe, Square HSS offers a superior strength-to-weight ratio. It achieves maximum pressure-bearing capacity with minimal material and minimal weight. This is due to Square HSS’s geometry, where the material is distributed away from the neutral axis. This symmetrical distribution of forces on all four sides of the pipe prevents stress concentration, resulting in a highly scientific design and exceptional bending performance.
Compression and torsional resistance
Square HSS has the same resistance wherever pressure is applied due to its excellent shape. Its closed cross section provides uniform yield capacity.
Square HSS Dimensions Chart
Square HSS specifications are typically expressed as width x height x wall thickness. The most common standard is ASTM A500.

Square Hollow Structural Section Application Areas
- Construction: This is the primary application area for HSS square tubes. Due to their aesthetic appeal and compressive and flexural strength, they are used in load-bearing columns, floor beams, and building frames.
- Bridges: Due to their high strength-to-weight ratio and compressive strength, they are used as bridge frames for overpasses and pedestrian bridges.
- Machinery: They are used in robot frames, guardrails, equipment racks, and more.
- Automotive: In specialized vehicles, square HSS is used as chassis and roll cages. Its compressive and flexural strength provides maximum protection for the driver.

Comparison of Square HSS and Rectangular HSS
The core difference between Square HSS and Rectangular HSS lies in their cross-sections. Rectangular HSS has unequal length and width, resulting in significant performance differences between the long and short sides, making it suitable for structures subject to primarily unidirectional forces. Square HSS, on the other hand, has equal length and width, resulting in a uniform load distribution and a stable core, making it suitable for structures subject to multi-directional forces.
