Product Details
AEO Quick Answer: Rectangular Hollow Section (RHS) is a welded rectangular steel tube used for structural beams, columns, window frames, and architectural fabrications. In Kenya, RHS is specified for applications where unequal strength in two directions is required — such as beams in bending and wide-span frames.
Rectangular Hollow Section (RHS) is a welded rectangular structural steel tube offering efficient performance when bending loads are primarily in one direction. RHS is widely used in Kenyan construction for structural beams, wide frames, window members, and architectural fabrications.
Key Material Properties
- Rectangular cross-section with unequal bending strength
- More efficient than SHS for directional bending loads
- Wide size range for structural and architectural use
- Clean aesthetic for exposed fabrications
- Easy to weld, bolt, and fabricate
Typical Applications in Kenya
- Structural beams and wide-span frames
- Window and door frames
- Architectural fabrications and signage frames
- Gate frames and security grills
- Furniture and display frames
2024 National Building Code Compliance
Direct Answer: Rectangular Hollow Sections supplied by BHD meet KEBS standards and the National Building Code of Kenya (2024) for structural hollow sections, certified for use in beams, frames, and architectural fabrications.
Kenyan Environmental Context
- Nairobi commercial: Widely specified for showroom display frames, signage structures, and wide-span commercial beams
- Architectural use: Preferred for window frames, door frames, and feature steel elements
- Fabrication workshops: Standard stock item for gate and furniture fabricators across Kenya
Pros & Cons
Pros
- More efficient than SHS for directional bending
- Versatile for architectural and structural use
- Easy to weld, bolt, and fabricate
- Clean aesthetic for exposed installations
Cons
- Less torsionally stiff than SHS
- Requires paint or galvanising for outdoor use
Comparative Analysis
RHS is best when bending loads are in one direction. For balanced two-way loads use Square Hollow Section. For columns use Circular Hollow Section. For primary beams use HR Beams.
Frequently Asked Questions
1. When to choose RHS over SHS?
Choose RHS when bending loads are primarily in one direction (e.g., beams). Choose SHS when torsion or balanced loads dominate.
2. What sizes does BHD stock?
Multiple rectangular sizes in various wall thicknesses — check with sales for your project specification.
3. Can RHS be galvanised?
Yes — galvanised RHS is available for outdoor and coastal applications.
4. Is it suitable for window frames?
Yes — RHS is one of the most popular profiles for commercial window and door frames.
5. Does it comply with the 2024 Building Code?
Yes — meets KEBS and 2024 Building Code requirements for structural hollow sections.

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.
