BRC Mesh in Kenya: Grades, Specifications, and How to Choose the Right One
Share
BRC mesh — also known as reinforcing mesh— is a prefabricated steel reinforcement made of longitudinal and cross wires welded at every intersection. It's used to reinforce concrete slabs, foundations, driveways, pavements, roads and bridges. It replaces the slower job of tying individual rebar or deformed bars on site. In Kenya, BRC mesh must be manufactured to KS 2177:2017 (Weld Mesh — Specification) and KS EAS 412-3:2019 (Steel for the Reinforcement of Concrete — Welded Fabric), both published by the Kenya Bureau of Standards.
What the grade number means
BRC mesh is sold in grades — A66, A98, A142, and others — where the number denotes the nominal steel cross-sectional area per metre, in both directions of the mesh. A higher number means thicker wire, more steel per square metre, and greater load capacity. This is a standard convention, not a Kenya-specific one — the same logic applies wherever weld mesh is manufactured to BS/EN-derived standards.
| Grade | Wire diameter | Mesh spacing | Typical use |
|---|---|---|---|
| A66 | 3.5mm | 200mm x 200mm | Light residential slab reinforcement, general floor work |
| A98 | 5mm | 200mm x 200mm | Medium-duty slabs, driveways, light industrial floors |
| A142 | 6mm | 200mm x 200mm | Heavy-duty slabs, industrial floors, higher-load pavement |
Roll vs. sheet: why it matters for your project
Most BRC mesh in the Kenyan market is sold in rolls, typically around 48 metres long. Shujaa Steel supplies BRC mesh as a continuous 48-metre roll, 2.1m wide. On a large pour, that means far fewer joints and overlaps to manage, less offcut waste, and faster laying — the labour and material savings compound on bigger slabs.
How to choose the right grade
Grade selection depends on the load the slab will carry and what your structural drawings or BOQ specify — this isn't a decision to make on price alone. As a rough guide:
- Residential floor slabs, boundary walls, light pavement: A66 is usually adequate.
- Driveways, commercial floors, light industrial use: A98 is the common mid-tier choice.
- Industrial floors, heavy vehicle loading, structural slabs: A142 or higher.
If your project has an engineer or BOQ specifying a grade, that spec overrides any general guidance here — follow it. If you're unsure, it's worth a quick check with your site engineer before ordering, not after the concrete's poured.
Installation basics
BRC mesh is laid within the formwork before the pour, positioned with the correct concrete cover (the depth of concrete between the mesh and the surface — this protects the steel from corrosion and is set by your structural drawings, not a fixed universal number). Sheets or roll sections are overlapped at the joints — typically one full mesh spacing — and tied with binding wire to keep the mesh from shifting during the pour. Mesh is usually supported on spacers ("chairs") to hold it at the correct height within the slab rather than resting on the ground. Exact cover depth and lap length should come from your structural drawings or engineer, not a generic guide — those numbers change with load and slab thickness.
Buying BRC mesh in Kenya: what to check
Before ordering, confirm three things with your supplier:
- KEBS compliance — ask which standard number the mesh is manufactured to, and whether the supplier holds a KEBS Standardization Mark for the product.
- Wire diameter and spacing — get exact figures, not just the grade name. Two suppliers' "A142" should match; if the numbers differ meaningfully, ask why.
- Manufacturer vs. reseller — a manufacturer controls the production line directly, which usually means more consistent spacing and diameter batch to batch, and pricing without a reseller markup.
FAQ
Is BRC mesh the same as weldmesh?
Yes — BRC mesh and welded wire mesh (weldmesh) are the same product: prefabricated steel mesh with wires welded at every intersection, manufactured to KS 2177:2017.
Can I mix grades on one project?
Yes, commonly — heavier-duty areas (driveways, loading bays) get a higher grade, lighter areas (walkways, boundary walls) get a lower one. Your BOQ or engineer typically specifies this per area.
Does BRC mesh replace rebar entirely?
Not always. BRC mesh handles distributed reinforcement in slabs efficiently, but structural elements like beams and columns still typically use conventional rebar. Which one (or both) applies to your project depends on the structural design.
