Ref 156 is a special mesh (100 × 100 mm spacing, 3.55 mm wire); all other references shown are standard 200 × 200 mm square mesh. Figures are from the RMS welded mesh factsheet; confirm exact wire diameters, mass and roll availability with your RMS branch or engineer for a specific project. See the full welded mesh factsheet.
Welded Mesh: Frequently Asked Questions
What is welded mesh?
Welded mesh, also called reinforcing wire mesh or steel mesh fabric, is a grid of steel wires welded together at every intersection. RMS welded mesh is made from cold-rolled deformed wire, joined by electric resistance welding for durable intersections with minimal loss of cross-sectional area. All RMS mesh complies with SANS 1024, with selected types also meeting BS 4482 tensile requirements.
What welded mesh sizes and references does RMS stock?
RMS stocks standard square mesh references from Ref 100 to Ref 888, supplied in standard sheets of 6 m by 2.4 m. Selected lighter references are also available in rolls for easier handling. Other mesh types or specifications can be sourced on request.
What is the difference between welded mesh and reinforcing bar?
Welded mesh arrives as a ready-made sheet and is ideal for wide, flat elements such as floor slabs, surface beds, driveways and road pavements, where it is far quicker to place than tying individual bars. Reinforcing bar (rebar) is placed and tied individually and suits columns, beams and specialised structural detailing. Many projects use both together.
Is RMS welded mesh SANS 1024 compliant?
Yes. RMS welded mesh is manufactured to SANS 1024, with a minimum proof stress of 485 MPa and a tensile strength of 510 MPa (BS 4482 compliant). Every sheet is clearly labelled for easy identification on site.
Can I buy welded mesh online, and does RMS deliver?
Yes. Welded mesh can be ordered through the RMS online shop, and it is stocked across the RMS national branch network with delivery throughout South Africa. RMS also exports stocked mesh across Southern Africa, with logistics support for bulk orders.
Does RMS cut welded mesh to size?
For health, safety and quality reasons, RMS does not cut mesh to size in the yard or on collection. Where a smaller piece is needed, mesh is cut to size on site. Remember to allow for laps where sheets overlap, so the reinforcement stays continuous across the slab.
