Reinforcing Mesh
Reinforcing Mesh is used for the reinforcement of concrete, is manufactured to SANS 1024:2006 and to other international standard specifications.
Features
Reinforcing Mesh mats are the most commonly used form of prefabricated reinforcement and is particularly suitable for flat slab construction and concrete surface beds. Other designed applications include:
Retaining and shear walls
Beams and columns
Concrete paving overlays
Precast concrete elements
Buildings project
Swimming pool and gunite construction
Reinforcing Mesh mats can be detailed as either flat or bent sheets, depending on the job requirements
Reinforcing Mesh reinforcement considerably reduces construction time
SANS 1024:2006 designated fabric mats are standard welded reinforcement mats and can be scheduled simply by reference to the fabric type, sheet dimensions and bending shape codes. (The reference is the nominal mass of the fabric in kg/m2 x 100).
The cold-rolled deformed wire used in welded mesh fabric has a characteristic strength (0.2% proof stress) a minimum of 485MPa compared to 450MPa for high tensile rebar. Fabric may be used at higher stresses than high tensile rebar resulting in a material saving of up to 8%.
Important design criteria
Placing of Fabric
In order to obtain the best results when using fabric reinforcement, special care must be taken to ensure that the mesh is positioned and maintained at the correct depth after the concrete pour. This can be done by using stools or plastic or concrete spacers. Another option is to place the fabric on poured concrete that has been leveled to the desired reinforcement depth. After placing the mesh the concrete can be topped up to the specified overall slab thickness.
Ideally fabric must be located 50mm from the top of the slab and where bottom steel is required, , it must also be supported 50mm above the substrate.
Lapping of Fabric Mats
It is recommended that in calculating the lap requirement for surface bed welded mesh fabric reinforcement that the formula shall be 25 x diameter + 150mm or 300mm, whichever is the greatest.
Quality
The Reinforcing Mesh is manufactured under strict quality controls with all standards conforming to SANS 1024:2006 standard specifications and tolerances and carries the certification mark.
