Slab Rib / Lintel
T-shaped design for strength over long spans. Propless on short spans under our supervision only.
3d Slab Installation GuideThis lintel is designed for high performance, intended to withstand stressful loads which most other lintels cannot handle. ( View our Typical Slab Layout ) Click here
This has been tested and certified for strength, precision, and efficiency. ( See the UJ University test report ) Click here
Props are moved further back under our engineer’s supervision, resulting in fewer props which significantly reduces installation time and costs. ( Interested in more of our Technical documents? ) Click here to view more
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.

Rib and Block Slab Benefits
- Manufacturing Benefitss
- Construction Benefits
- Design Benefits
- Suitable Applications
- Service / Delivery Areas
- Factory produced to the highest standards
- T Lintels are machine extruded and not made in molds like our competitors, therefore the underside of our lintel is rough, 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 labour
- 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
- Hospitals
- Schools
- Residential/ Domestic
- Town Houses
