Circular Hollow Sections (CHS) are manufactured from structural carbon steel through hot-rolling or cold-forming processes into seamless or welded round tubes. The circular geometry provides uniform strength in all directions, making CHS highly efficient in handling axial loads, bending, and torsion.
Key technical properties include:
-
High compressive and tensile strength
-
Excellent torsional resistance compared to open sections
-
Uniform stress distribution
-
Smooth, round external profile
-
Compatibility with welding, bolting, and fabrication systems
Because of their geometry, CHS members use material efficiently, often achieving the same structural performance as heavier sections with reduced steel weight.
Common applications in Kenya include:
-
Structural columns and pillars
-
Roof trusses and space frames
-
Handrails, balustrades, and guardrails
-
Canopies, sheds, and carport frames
-
Industrial frameworks and support structures
2024 National Building Code Compliance
CHS supplied by BHD are suitable for use under the National Building Code of Kenya (2024), which emphasizes:
-
Structural integrity and load-bearing safety
-
Approved steel sections for buildings and infrastructure
-
Material traceability and quality assurance
Engineers favor CHS for projects requiring predictable structural behavior and compliance with modern safety standards.
Kenyan Environmental Context
Kenya’s diverse environments require steel sections that perform reliably:
-
Urban & high-UV areas (Nairobi, Thika): CHS maintains strength and alignment when protected with standard primers and industrial coatings.
-
Coastal regions (Mombasa, Malindi): With proper anti-corrosion treatment, CHS resists saline air degradation.
-
High rainfall & humid zones (Kisumu, Kakamega): The closed circular profile minimizes water trapping, reducing corrosion risk compared to open sections.
Protective finishes such as red oxide primer, epoxy paint, or galvanization are recommended for outdoor use.
Pros & Cons
Pros
-
Uniform strength in all directions
-
Excellent resistance to torsion and buckling
-
Clean, modern architectural appearance
-
Reduced corrosion risk due to closed section
-
Efficient use of steel material
Cons
-
More complex connections compared to flat sections
-
Slightly higher fabrication cost than open profiles
-
Requires precision cutting for joint accuracy
Comparative Analysis: CHS vs. Square Hollow Section (SHS)
While Square Hollow Sections (SHS) offer easier flat-surface connections, CHS provides superior torsional strength and uniform load performance. For columns, exposed structures, and wind-loaded applications in Kenya, CHS is often the preferred structural choice.
Frequently Asked Questions (FAQs)
1. What is CHS steel used for?
It is used for columns, trusses, handrails, and structural frameworks.
2. Is CHS suitable for outdoor construction?
Yes, when treated with appropriate corrosion protection.
3. Does CHS meet Kenyan building standards?
Yes, it aligns with the National Building Code of Kenya (2024).
4. Is CHS stronger than flat or angle sections?
It offers better torsional and buckling resistance due to its circular shape.
