A plain-English guide to what structural steelwork really is, when to use it in Kenya, and what to ask your contractor before signing.
Structural steelwork is the engineered skeleton of a building — the columns, beams, trusses and braces that carry every other load, from cladding to wind to the racking inside your warehouse. If you are developing property in Kenya, understanding it early helps you avoid the costly re-work that comes from late design decisions.
There are two main families of steel frames used here: portal frames for single-storey warehouses, factories and showrooms, and multi-storey frames for offices and mixed-use buildings. Portal frames give you long column-free spans, which is what makes a warehouse useful. Multi-storey frames give you flexibility on each floor.
Compared with reinforced concrete, steel is lighter for the same load, which means smaller foundations and faster construction. A typical mid-sized warehouse can be fabricated in our yard while the foundations are being cast, so the frame goes up almost as soon as the slab is cured. That speed compresses your financing window and gets you to revenue sooner.
Quality control matters more than the steel itself. Ask your contractor where the welding happens, who inspects it, what coating system is used and how the holding-down bolts are surveyed before the frame arrives. Good answers to those four questions separate professional steel contractors from the rest.
