BRC reinforcement mesh (A142 – A393) and galvanized welded mesh rolls for slabs, blockwork and enclosures.
Product overview
Welded wire mesh is a grid of steel wires welded at every crossing. Heavy BRC mesh to BS 4483 reinforces concrete slabs, while light galvanized (GI) welded mesh in rolls is used for fencing, enclosures and blockwork.
BRC mesh comes in flat sheets with 200 × 200 mm squares. The type number tells you the steel area: A142 uses 6 mm wire for light slabs, while A193, A252 and A393 use thicker wire for heavier floors.
Light GI welded mesh is made from thin galvanized wire in small apertures and sold in rolls. It is used for animal and garden enclosures, guards, plaster and blockwork reinforcement.

Questions
A142 is commonly used for light slabs and screeds, and A193 or A252 for heavier floors. Always follow the structural drawing, which states the mesh type.
BRC mesh is heavy reinforcing mesh in flat sheets for concrete. GI welded mesh is light galvanized wire in rolls, used for fencing, guards and blockwork, not for structural slabs.
