Ceiling Grid Systems
T38 exposed grid and T37 concealed grid — the two systems behind every suspended and flush plastered ceiling in South Africa. Both in stock at our Edenvale warehouse.
T38 exposed grid and T37 concealed grid — the two systems behind every suspended and flush plastered ceiling in South Africa. Both in stock at our Edenvale warehouse.
The grid you choose determines the look, the finish and what goes into it. They are two completely different systems — not interchangeable.
Visible white or black grid lines. Acoustic or vinyl ceiling tiles drop in from above. Fast installation, easy tile access. The commercial standard across SA offices, schools, retail and clinics.
Grid is completely hidden. 9mm gypsum board screws up from below, taped and skimmed. Smooth, seamless plastered ceiling. Standard for homes, upmarket offices and all bulkheads.
The T38 suspended grid is the most widely used exposed ceiling grid in South Africa. Featuring a 38mm main runner height and 24mm face width, it is available in pre-painted white or black finishes. Acoustic or vinyl ceiling tiles drop into the grid from above — no adhesive, no screws. The system uses 3 connection points per main tee for a rigid, stable installation and provides quick access to services above, including wiring, ducting, air conditioning and lighting.
Available in both finishes — black grid creates a dramatic, contemporary look in retail and hospitality spaces.
Tiles lift out in seconds without tools — essential where services above need regular access.
Fire-rated version available — independently tested to achieve a 60-minute fire rating in compliant systems.
Quick clip-together system with main tees, cross tees and wall angles for reduced labour time on site.

The T37 concealed grid (screw-up grid) is a strong, adjustable galvanised steel framework for flush plastered and seamless ceilings. The T37-profile main tee pairs with a T32-profile cross tee to create a concealed framework that supports 9mm gypsum board screwed up from below. Once the board is taped and skimmed, the grid is completely invisible — producing a smooth, uninterrupted plastered ceiling. It is also the standard system for building bulkheads around aircon units, beams and architectural features. Faster to install than traditional timber brandering and compatible with fire-rated boards.
Grid is completely hidden under the board — no visible grid lines, no exposed tees. A perfect flush plastered finish.
The standard specification for bulkheads around aircon ducts, beams and feature lighting runs.
Galvanised zinc coating provides durability and corrosion resistance in freshly plastered environments.
Minimal ceiling drop — ideal for rooms with height restrictions where every millimetre counts.
