What are the key features of circular hollow sections?
The key circular hollow section properties are the reason for these sections’ versatility and popularity. The key features include excellent strength-to-weight ratio, torsional resistance and structural efficiency, and aesthetic appeal and versatility.
Excellent strength-to-weight ratio
An excellent strength-to-weight ratio is one of the most important features of circular hollow sections. The tubular structure of these sections keeps them lightweight while enabling them to support incredibly heavy loads. This property makes these sections an excellent choice for applications that require reduced weight without compromising strength, such as bridges, offshore structures, and scaffolding.
Torsional resistance & structural efficiency
The torsional resistance of high-quality circular hollow sections is much greater compared to that of other steel sections. Their symmetrical shape enhances their overall structural efficiency, reducing weak points and enabling them to distribute stress evenly. These key features make circular hollow tube sections particularly suitable for use in high-rise buildings, industrial piping systems, and other high-stress environments and load-bearing applications.
Aesthetic appeal & versatility
The key circular hollow section properties go beyond structural advantages. The smooth, uniform appearance of these sections makes them a popular choice for sleek, visually appealing architectural designs. They’re also versatile, as they can be fabricated, welded, or otherwise customised for greater flexibility in different industries.
Compliance & standards
Whether ordering circular hollow sections for architectural, construction, industrial, or other needs, it’s vital to ensure compliance with industry standards to ensure durability, integrity, and reliability. Sections from SPS meet or exceed safety and quality standards such as:
ASTM A500: This is a North American standard specification for cold-formed welded structural steel tubing.
EN 10210: This standard applies to hot-finished structural steel hollow sections.
EN 10219: A standard for cold-formed structural hollow sections.
ISO 9001: This quality management system certification ensures high manufacturing standards.
What are the applications of circular hollow sections?
Among the most versatile of all hollow steel sections, circular hollow sections have an impressive range of applications. Among these are:
Architecture & design: Different circular hollow section dimensions are featured in artistic installations and modern buildings, and they’re used as decorative elements.
Construction: Circular hollow steel sections are used in beams, columns, and frames for bridges, other infrastructure projects, and buildings.
Engineering: Circular hollow section properties see these components used widely in industrial frameworks, mechanical structures, and transportation infrastructure.
Oil & gas industry: Sections made from high-quality steel are used in pipelines, offshore structures such as rigs, and support systems in the oil and gas industry.
Renewable energy: These sections are used extensively in hydroelectric projects, solar panel supports, and wind turbine towers.
What are the different grades of circular hollow sections?
SPS provides circular hollow sections in different grades to suit different applications and environmental conditions. Among these grades are:
E355: This seamless steel grade is ideal for hydraulic systems and precision engineering applications.
S235JRH: This structural steel grade is known for its moderate strength and good weldability.
S355J2H: Indicating exceptional strength, this grade is ideal for applications that demand excellent load-bearing properties.
