Guide to Hollow Sections in Kenya: SHS & RHS Uses, Sizes & Applications | BHD Kenya
Hollow steel sections are among the most widely used structural steel products in Kenya’s construction and fabrication industry. They are essential in modern buildings, steel frameworks, trusses, and fabrication works due to their strength, versatility, and clean architectural finish.
In Kenya, contractors, engineers, and fabricators commonly use hollow sections in residential, commercial, and industrial projects. These sections are especially important in Nairobi, Mombasa, and industrial towns like Athi River where steel fabrication is heavily used in construction.

What Are Hollow Sections?
Hollow sections are structural steel tubes with hollow cross-sections used in construction for load-bearing, framing, and structural support applications.
They are available in different shapes:
- Square Hollow Sections (SHS)
- Rectangular Hollow Sections (RHS)
- Circular Hollow Sections (CHS)
Each type serves different engineering and architectural purposes depending on load requirements and design specifications.
Types of Hollow Sections in Kenya
1. Square Hollow Sections (SHS)
SHS are steel tubes with equal width and height dimensions, forming a square profile.
They are widely used in:
- Steel gates and fences
- Building columns
- Structural frames
Explore related materials in the steel products catalog.
2. Rectangular Hollow Sections (RHS)
RHS have a rectangular shape and are commonly used where directional strength is required.
They are ideal for:
- Roof trusses
- Structural beams
- Framework construction
3. Circular Hollow Sections (CHS)
CHS are round steel tubes used for aesthetic and structural applications.
They are commonly used in:
- Railings
- Architectural structures
- Columns and supports
Common Sizes of Hollow Sections in Kenya
Hollow sections are available in different sizes depending on structural requirements.
Typical Size Range:
- SHS: 20x20mm to 200x200mm
- RHS: 40x20mm to 250x150mm
- Thickness: 1.2mm to 10mm depending on load
Applications of Hollow Sections in Construction
1. Structural Frameworks
Hollow sections are widely used in building skeletons and steel frames due to their strength-to-weight efficiency.
2. Roofing Systems
They are used in trusses and support structures in industrial roofing systems.
3. Fabrication Works
Used in gates, doors, staircases, and security structures.
4. Architectural Design
Modern buildings use hollow sections for visible structural aesthetics.
Advantages of Hollow Sections
Structural Benefits
- High strength-to-weight ratio
- Excellent load distribution
- Resistance to bending and torsion
Construction Benefits
- Easy fabrication and welding
- Clean architectural finish
- Suitable for modular construction
Economic Benefits
- Efficient material usage
- Reduced construction costs
- Long lifespan with minimal maintenance
Hollow Sections vs Solid Steel Bars
| Feature | Hollow Sections | Solid Bars |
|---|---|---|
| Weight | Lightweight | Heavy |
| Strength | High efficiency | High but heavier |
| Cost | More economical | Higher material usage |
| Usage | Structural frames | Reinforcement |
Climate Considerations in Kenya
Coastal Regions (Mombasa, Kilifi)
- High humidity and salt exposure
- Galvanized hollow sections recommended
Nairobi & Central Kenya
- Moderate climate conditions
- Standard steel sections perform well
Arid Regions
- Wind load considerations important
Fabrication and Installation Considerations
Key Requirements:
- Proper welding techniques
- Accurate cutting and alignment
- Corrosion protection (painting or galvanizing)
- Structural load calculations
Incorrect fabrication can compromise structural integrity and safety.
Common Mistakes When Using Hollow Sections
- Using incorrect thickness for load requirements
- Poor welding quality
- Ignoring corrosion protection
- Incorrect structural spacing
