What Are The Common Shapes And Sizes Of Hollow Structural Sections?


Hollow structural sections (HSS) are steel or aluminum factors with a hollow cross-segment, that distinguish them from solid sections by way of their empty interiors. Usually used in construction, infrastructure, and engineering tasks, HSS offers numerous benefits. They provide power and stability while decreasing weight compared to solid sections, making them ideal for applications in which weight reduction is crucial. HSS is available in various shapes, inclusive of square, square, and round, each presenting specific structural homes and design flexibility.

Additionally, HSS is to be had in fashionable sizes described by enterprise standards and specs, ensuring compatibility and simplicity of integration into tasks. The hollow structural section can be fabricated by using different production processes, including warm or bloodless forming, welding, or extrusion. HSS discovers applications in a wide range of industries, consisting of building creation, infrastructure development, car engineering, and aerospace, due to their versatility, durability, and efficiency in structural design.

Common Shapes And Sizes Of Hollow Structural Sections (HSS)

Hollow structural sections (HSS) are essential additives in current engineering and production, providing versatility, power, and efficiency in structural design. HSS is available in an expansion of sizes and styles, each tailored to unique applications and engineering requirements. This article delves into the common sizes and styles of HSS, exploring their traits, advantages, and ordinary applications.

Rectangular Hollow Sections

Square hollow sections (RHS) are structural factors with a rectangular cross-section, characterized by immediate facets and sharp corners. To be had in a selection of sizes and thicknesses, RHS gives versatility in engineering layout. Usually used in building production, infrastructure tasks, and industrial packages, RHS presents efficient load-bearing capabilities and simplicity of connection due to its flat surfaces and immediate edges. Its geometric residences make it suitable for various structural frameworks and architectural designs.

Square Hollow Sections (SHS)

Rectangular hollow sections (SHS) are structural components characterized by a rectangular pass segment with equal sides and sharp corners. To be had in various sizes and thicknesses, SHS provides uniform load-bearing ability and simplicity of fabrication. Extensively used in structural frameworks, architectural elements, and equipment components, SHS provides symmetrical geometry and efficient utilization of space. Its versatility and structural integrity make it appropriate for diverse applications in production, engineering, and production initiatives.

Round Hollow Sections (CHS)

Round hollow sections (CHS) are structural elements with a round cross-segment, imparting an ultimate strength-to-weight ratio and resistance to torsional loading. Available in a range of diameters and wall thicknesses, CHS offers versatility in engineering layout. Generally used in structural columns, poles, and trusses, CHS gives a uniform distribution of stress and greater balance. Its curved profile allows for an efficient load switch and decreased cloth usage, making it appropriate for various applications in creation and infrastructure initiatives.

Sizes Of Hollow Structural Section


Hollow structural sections (HSS) come in fashionable sizes defined via industry standards and specifications such as ASTM, EN, and ISO. The dimensions of HSS include outer dimensions (width, top, or diameter), wall thickness, and length. Trendy sizes are generally expressed in metric or imperial units, with variations based totally on local choices and manufacturing abilities. These standardized sizes ensure compatibility and simplicity of integration into construction and engineering tasks.


The thickness of hollow structural section (HSS) partitions varies depending on structural necessities and packages. Wall thicknesses range from thin-walled sections for light-weight structures to thick-walled sections for heavy-duty applications requiring excessive load-bearing capacity. The choice of wall thickness is vital to ensuring certain structural integrity and performance, with thinner walls imparting weight savings and thicker partitions presenting stronger strength and stiffness. Standardized thicknesses are designated by industry requirements and regulations to satisfy engineering specifications.


Hollow structural sections (HSS) are typically supplied in fashionable lengths to facilitate construction and meeting processes. Preferred lengths vary depending on manufacturing practices and transportation constraints. Custom lengths may be fabricated to fulfill unique task necessities, considering the efficient utilization of substances and minimizing waste. Standardized lengths ensure compatibility and ease of integration into production and engineering projects.


Hollow structural sections (HSS) offer a diverse range of sizes and styles tailor-made to specific engineering necessities and applications. The unique shapes and sizes of hollow sections make them indispensable in construction creation, infrastructure initiatives, commercial equipment, and transportation systems. With information on the traits, benefits, and common applications of HSS, engineers, and architects can make use of these flexible additives to create modern and sustainable systems for a huge range of industries and projects.
