Slab Rib / Lintel
T-shaped design for strength over long spans. Propless on short spans under our supervision only.
This lintel is designed for high performance, inteded to withstand stressful loads which most other linntels cannot handle.(View our typical Slab Layout) Click Here.
This has been tested and ertified for strength, precision and efficiency. (See the Wits University test report) Click Here.
Props are moveed further back under our engineers supervision, resulting in less props which significantly reduces installation time and costs. (Interested in more of our Technical documents?) Click here to view more.
A furthere 5^ concrete saving is achieved as a result of the unique T-Shape spans over 5m are straight and perpendicular for hassle free propping.

We also stock lightboxes for downlights
Ref . 100 Mesh
Anti-crack welddmesh supplied as part of the package or as required.
The anit crack weld mesh provides durability to the structure by minimising surace cracks when exposed to the elements.
T10 or Y12 Rebar
Stiffener steel supplied as part of the package or as required.
Ribs are propped at regular 1.5m intervals and under every block. Reinforcing bars are inserted above to form stiffener rib when enhances slab stability.
Used by electricians for downlights.

- Factory produced to the highest standards
- T Lintels are machine extruded and not made in moulds like our competitors, therefore the
underside of our lintel is rogh, which serves as a good plaster adhesive surface
- 40MPA concrete lintels is our standard, as opposed to 25MPA industry standards
- Blocks made from quality aggregates with minimum breakages
- Level Soffit – Lintels and Blocks fit perfectly, reducing plastering headaches
- Most common slab system in SA for over 40 years
- A further 5% concrete saving is achieved as a result of the unique T-Shape spans over 5m are straight and perpendicular for hassle free propping.
- Well understood by all builders, contractors and sub contractors and South African unskilled
- No cranes required, erection can be done by unskilled labour
- Light fittings, electrical and plumbing are easily inserted by omitting hollow blocks
- Eliminates Soffit shuttering (In-Situ Slabs) and no steel reinforcement is required
- Flexibility and versatility of design approach
- Spans up to 8m are easily achieved
