Sleeves for Plastic Tanks


Corrugated steel tank sleeves can be used to cover and conceal plastic or other tanks.

  • The sleeve does not have a base or top and does not need to be sealed and is therefore cost effective.
  • The sleeves can also be transported in concentric rings which reduces volume and transport costs.
  • We can custom make to fit any size plastic tank, the sleeve diameter is normally 3oomm larger than the plastic tank diameter.
  • If the top of the tank is visible we can supply a tank lid.

New tanks:

Corrugated steel sleeves around plastic tanks offer an aesthetically pleasing solution to rain water harvesting if you have a roof made of either zinc alume or chromadek ( both of which are not compatible with galvanised steel tanks) , as the rainwater is not in contact with the galvanised  steel.

Existing plastic tanks:  

Corrugated steel sleeves can be fitted around existing tanks. Holes will need to be cut to accommodate existing piping and connections.

Sleeve kits:

We can supply the corrugated rings to cover a plastic tank. The rings can be nested together to reduce transport costs.

Delivered and assembled:

We can offer this service in Cape Town and Johannesburg. Distance, access to the tank site; piping and outlets will be taken into account to prepare a quote.
