Product Details
Circular Hollow Section (CHS) is a welded round structural steel tube used for columns, trusses, handrails, fencing, and architectural frames. In Kenya, CHS is specified for its equal strength in all directions, clean aesthetic, and efficiency in compression — making it the preferred choice for columns and trussed structures.
Circular Hollow Section (CHS) is a welded round structural steel tube widely used where equal strength in all directions is required. Its round geometry delivers superior buckling resistance under axial load, making CHS the most efficient section for pure compression columns and trussed frames in Kenyan construction.
Key Material Properties
- Round geometry — equal strength in all directions
- Superior buckling resistance under compression
- Clean aesthetic ideal for exposed architectural use
- Size range from 20mm OD to 200mm+ OD
- Welded seam construction for consistent wall thickness
Typical Applications in Kenya
- Columns for warehouses and open-sided sheds
- Architectural roof trusses and space frames
- Handrails, balustrades, and balcony railings
- Steel fencing, gates, and bollards
- Playground equipment and street furniture
2024 National Building Code Compliance
Circular Hollow Sections supplied by BHD comply with KEBS standards and the National Building Code of Kenya (2024) for structural hollow sections, certified for use in load-bearing columns, trusses, and architectural frames.
Kenyan Environmental Context
- Nairobi commercial: Widely specified for exposed structural columns in showrooms, car parks, and commercial entrances
- Architectural design: Round CHS gives a modern aesthetic prized by Kenyan architects for feature structures
- Industrial infrastructure: Standard for warehouse columns, trussed sheds, and fabrication frameworks
Pros & Cons
Pros
- Most efficient shape for compression (columns)
- Equal strength in all directions
- Clean visual appearance for exposed use
- Lower surface area for painting and maintenance
Cons
- Harder to connect than square sections (needs cut profiles)
- Less efficient than I-beams for pure bending
Comparative Analysis
CHS is the most efficient choice for compression columns. For square-section structural framing use Square Hollow Section. For rectangular beams use RHS. For smaller round pipes under 76mm use CHS 16mm–76mm.
Frequently Asked Questions
1. Why is CHS preferred for columns?
Round geometry resists buckling equally in every direction — the most structurally efficient shape under compression.
2. What sizes does BHD stock?
From small-diameter CHS (20mm OD) up to large structural pipe (200mm+ OD) in multiple wall thicknesses.
3. Can CHS be galvanised?
Yes — galvanised CHS is available for outdoor, coastal, and humid environments.
4. How is CHS connected?
Welded, bolted via flange plates, or joined with proprietary connectors for space frames.
5. Is it compliant with the 2024 Building Code?
Yes — BHD CHS meets KEBS and National Building Code 2024 structural requirements.

MS Flat Bars
MS Flat Bars — MS Flat Bars are rectangular-cross-section mild steel bars used for fabrication, framing, and general metalwork. In Kenya they are a universal workshop consumable — essential for gate frames, window grills, bracket fabrication, stiffener strips, and virtually every kind of light steel fabrication.
Binding Wire
Binding Wire — Binding Wire is soft annealed mild steel wire used to tie reinforcement bars together on construction sites. In Kenya, 16-gauge black annealed binding wire is the standard material for tying TMT rebar in columns, beams, slabs, and foundations — an essential consumable for every reinforced concrete project.
HR Channel
HR Channel — HR Channel is a hot-rolled structural steel section with a U or C-shaped profile used for beams, columns, bracing, and industrial fabrication. In Kenya, HR Channel is specified for warehouse framing, industrial plant support, vehicle chassis, and fabricated structural connections where flanged support is required.
HR Beams
HR Beams — HR Beams are hot-rolled structural steel I-beams and H-beams used as primary load-bearing members in commercial, industrial, and infrastructure construction. In Kenya they are the backbone of multi-storey buildings, warehouses, factories, and bridges — delivering maximum strength-to-weight efficiency for spanning and column applications.
