Tank Shell
The Kulula Tank is a high-quality modular steel tank engineered for durability, easy transport, and fast installation.
Panels are manufactured from ALUZINC steel, offering a lifespan up to 7 times longer than standard galvanized steel.
Sheet thickness ranges from 0.75 mm to 1.1 mm, CNC-punched for precise bolt alignment and profiled to our exclusive V-Lock system.
Each panel is smoothly curved to the correct radius, ensuring structural strength and a perfect circular finish.
PVC Liner
All Kulula Tanks are equipped with a food-grade PVC liner to prevent stored water from contacting the tank shell.
Key features include:
Dome Roof
The Kulula Tank is not designed for a roof structure.
If a roofed tank is required, we recommend upgrading to the Nyane Tank.
Fasteners
STS Tanks uses only M10 Grade 8.8 hot-dip galvanized bolts and nuts, ensuring long-term structural reliability.
All fasteners are torqued using electric impact wrenches for consistent tension and superior assembly quality.
Installation
Thanks to its compact modular design, the Kulula Tank can be flat-packed and transported easily—even in a standard LDV (bakkie).
With minimal tools and manpower, installation is quick and efficient, and the tank is ready for immediate use after assembly.
Site Preparation
Only simple preparation is required:
This provides a stable and cost-effective base for the tank.
Applications
The Kulula Tank is ideally suited for:
• The Aluzinc shell and galvanised roof of your tank(s) is covered by a ten (10) year warranty against structural failure from the installation date.
• The Aluzinc shell and galvanized roof are covered against corrosion for a period of ten (10) years from the installation date.
• The PVC liner is covered by a two (2) year warranty against material failure or poor workmanship on condition that a metal roof is installed on the date of installation and that the water level is retained at 100%.
• The tank is covered by a one (1) year installation warranty from date of installation.
