 Mecca Reinforcing
Reinforcing
Mecca Reinforcing (Pty) Ltd is a subsidiary of the RMS (Reinforcing and Mesh Solutions (Pty) Ltd) group who are supplied with reinforcing bar from Mittal Steel, the world’s largest steel producer. The bars are supplied in standard diameters, lengths and grades of steel as per the following:
High tensile steel (SANS 920:2005 - 450Mpa) - denoted by the letter "Y", deformed bar
| Diameters available (mm) |
8; 10; 12; 16; 20; 25; 32 and 40mm |
Mild steel (SANS 920:2005 - 250Mpa) - denoted by the letter "R", smooth bar
| Diameters available (mm) |
8; 10; 12; 16; 20; 25; 32 and 40mm |
Standard Lengths which are available for both Grades
13m; 12m
Note : Special diameters, lengths and grades are available on request.
Mecca Reinforcing (Pty) Ltd. cuts and bends the bar to the SANS 282/2004 specification. The finished product can then be delivered and installed as per the accepted quotation. Using well maintained and modern equipment, delivery times are kept to a minimumnerally .
Bending Schedules
Mecca Reinforcing (Pty) Ltd will generally cut and bend the bar according to the bending schedules supplied by the customer. Where bending schedules are not available, Mecca Reinforcing (Pty) Ltd has the expertise to assist with the drawing-up of bending schedules and using these for quotation and production purposes. All bending schedules should refer to the standard Shape Codes as per the table below:
Shape Code Table (SANS 282:2004, Edition 5.1)
NOTE1: Use shape code 99 for all other shapes. A dimensioned sketch of the shape shall be given in the bending schedule.
NOTE2: Radii of all bends are standard unless r is given in the bending schedule.
NOTE3: All dimensions are external (outside) dimensions.
Site Installation / Steel Fixing
As part of Mecca Reinforcing's (Pty) Ltd affirmative action policy, the site installation and tying of reinforcing is predominantly carried out by previously disadvantaged subcontractors who are closely assisted and managed by a competent team of Mecca Reinforcing supervisors.
Welded Mesh Reinforcing
Welded mesh reinforcing is a convenient and cost effective alternative to conventional bar reinforcement for the following reasons :
- The mesh is generally specified and manufactured according to standard references making for easy site identification, quality control and management.
- The mesh is manufactured in sheets or rolls resulting in a quick and simple site installation process.
Although generally used in surface beds (concrete floor slabs on fill) and concrete roads, mesh can also be used in suspended floor slabs, concrete walls, culverts / drains and composite brick / concrete retaining walls.
RMS is one of the few manufacturers of welded mesh in Southern Africa, which has a full SANS 9001 : 2000 quality rating. The manufacture process is as follows:
- Mittal Steel supply RMS with medium-low carbon mild steel rod
- The mild steel rod is cold rolled by RMS to the required diameter to form high tensile wire
- The high tensile wires are welded into a rectangular mesh grid fabric

Design Mesh
Where there is a significant amount of repetition, conventional bar reinforcement designs can be substituted by design mesh. Mecca Reinforcing (Pty) Ltd has the facility to implement this process in conjunction with the project engineer. The premanufacturing of the design mesh results in :-
- Easier site control and less skills required on site
- Quicker installation compared to that of conventional reinforcing
