Hollow steel tube, also known as steel hollow section, is a versatile structural element widely used in construction and engineering projects. It is a type of steel profile characterized by its hollow cross-section, which can be circular, rectangular, or square in shape. These tubes are manufactured through a process of hot or cold forming, where steel is shaped into the desired profile and welded along the seam.
The unique design of hollow steel tubes offers several advantages over solid steel sections. Their hollow nature provides an excellent strength-to-weight ratio, making them ideal for applications where both structural integrity and weight considerations are important. Furthermore, the sealed structure of these tubes offers higher durability against torsional stress and twisting stresses, making them suitable for a variety of applications that require load bearing.
Hollow tube materials have become known for their durability, resistance to corrosion, and appealing appearance. They are simply treated or repainted to enhance their visual appeal and provide protection against environmental factors. The smooth surface of these tubes also makes them easy to clean and maintain, contributing to their popularity in both industrial and architectural settings.

Hollow steel tube Types:
Rectangular Hollow Sections (RHS)Rectangular Hollow Sections, or RHS, are characterized by their elongated rectangular cross-section. These tubes offer excellent strength in both the major and minor axes, making them suitable for use as columns, beams, and trusses. RHS are particularly popular in construction projects where a sleek, modern aesthetic is desired. They provide a clean, linear appearance that architects and designers often incorporate into their plans.
RHS are available in a wide range of dimensions, allowing for flexibility in design and application. Their flat sides make them easy to connect to other structural elements, and they can be easily welded or bolted together. This versatility makes RHS a popular choice in the construction of buildings, bridges, and other large-scale structures.
Square Hollow Sections (SHS)
Square Hollow Sections, or SHS, feature a square cross-section with equal sides. This symmetrical shape provides uniform strength in all directions, making SHS ideal for applications where loads are applied from multiple angles. SHS are commonly used in the construction of frames, support structures, and columns.
The square shape of SHS offers a balance between the sleek appearance of RHS and the strength distribution of circular sections. This makes them a versatile choice for both structural and aesthetic purposes. SHS are often used in the construction of furniture, machinery frames, and architectural features where a strong, clean-lined appearance is desired.
Circular Hollow Sections (CHS)
Circular Hollow Sections, or CHS, have a round cross-section. This shape provides excellent resistance to torsional forces and uniform strength distribution around its circumference. CHS are particularly well-suited for applications involving compression loads, such as columns and support structures.
The smooth, curved surface of CHS makes them aesthetically pleasing and reduces wind resistance, making them popular in outdoor applications such as signposts, streetlights, and scaffolding. Their shape also allows for easy connection of multiple sections at various angles, making them ideal for complex structural designs.
Applications:
Hollow steel tubes find applications across a wide range of industries due to their versatility and structural properties. In the construction industry, they are used extensively in the framework of buildings, bridges, and stadiums. Their high strength-to-weight ratio makes them ideal for creating large, open spaces without the need for numerous support columns.
In the automotive industry, they are used in the manufacture of vehicle chassis and roll cages, providing strength and safety while keeping vehicle weight down. The energy sector utilizes these tubes in the construction of offshore platforms, wind turbine towers, and pipeline supports.
Hollow steel tubes also play a crucial role in the manufacture of furniture, particularly in modern designs that emphasize a sleek, industrial aesthetic. They are used in the creation of table and chair frames, shelving units, and other decorative elements.
In agriculture, these tubes are employed in the construction of greenhouses, livestock shelters, and irrigation systems. They are an excellent choice for applications outside where vulnerability to the climate is a concern due to their durability and resistance to rust.
For the fabrication of railings, obstacles, and signposts surrounding highways and roadways, the shipping profession uses hollow steel tubes. Their strength and ability to absorb impact make them an important component in ensuring road safety.
Hollow Steel Tube Manufacturer:
When selecting a hollow steel tube manufacturer, it's crucial to consider factors such as product quality, manufacturing capabilities, and customer service. One such manufacturer is LONGMA GROUP, which specializes in the production of high-quality hollow steel tubes.
LONGMA GROUP's hollow steel tubes are available in various grades, including S235, S275, and S355. These grades refer to the minimum yield strength of the steel, with S355 being the strongest of the three. The choice of grade depends on the specific requirements of your project, taking into account factors such as load-bearing capacity and environmental conditions.
S235 grade tubes are suitable for general-purpose applications where moderate strength is required. S275 offers increased strength and is often used in more demanding structural applications. S355, with its high yield strength, is ideal for heavy-duty applications where maximum strength and durability are essential.
