Multi-Storey Steel Buildings in Nairobi
Avonstructures designs and erects multi-storey steel buildings using welded and hot-rolled I- and H-shaped sections. Steel frames let developers in Nairobi go higher, faster, with adaptable floor plates and column-free retail or office spaces.
What is Multi-Storey Steel Buildings?
Multi-storey steel buildings use a gravity load system of beams and columns combined with a lateral system of braced or moment-resistant frames to carry wind and seismic forces.
Compared with reinforced concrete, steel frames offer a high strength-to-weight ratio, larger spans, faster erection, factory-controlled quality, adaptable floors and excellent lateral-load resistance.
Floors are formed on heavy duty decking sheet acting as permanent formwork — it carries the wet concrete without timber shuttering, speeds up the floor cycle and works compositely with the cured slab.
What to expect

Concept design and structural option study.
- 02
Detailed engineering — gravity and lateral systems.
- 03
Foundation and core coordination with the civils crew.
- 04
Shop fabrication of columns, beams and braces.
- 05
Floor-by-floor erection with deck and stair installation.
- 06
Fireproofing, services coordination and handover.
Why this works
Higher, Lighter
Less weight on foundations, more rentable space.
Open Floors
Long spans free up retail and office layouts.
Speed
Frames go up while finishes start below.
Adaptable
Tenant fit-outs can be reconfigured easily.
Lateral Strength
Braced or moment frames for wind and seismic.
Quality Welds
Critical connections welded in controlled shop conditions.

Frequently asked questions
Steel frames are well suited up to medium-rise (8–15 storeys) for commercial use in Kenya; taller buildings are achievable with composite design.
Material cost per kilo can be higher, but lighter foundations, faster programme and reduced finance cost often make total project cost competitive.
Yes, when designed with the correct fireproofing — board, spray or intumescent — to meet the required fire-resistance period.
Through braced bays, moment-resisting connections or a concrete core, chosen for the building's geometry and occupancy.
Yes. Bolted connections and composite slabs make tenant fit-out changes faster than in concrete frames.
