Commercial - Corrugated Steel Water Tanks

Rhino Water Tanks specialise in the manufacture of commercial corrugated water tanks. Our modular design allows the tanks to be easily transported in kit form and built on site.

All corrugated wall sheets are rolled from BlueScope steel and roof trusses are hot dipped galvanised for durability. Rhino's industrial strength reinforced Metallocene coated liners are UV treated, making them even suitable for applications without a roof and can be used for a range of liquids including high or low pH, effluent and recycled water.

Tank Sizes

Rhino corrugated water tanks are available in a variety of standard sizes or can be custom designed to meet specific customer or project requirements.

Our range of commercial tanks is available in 5 height specifications as shown below.

Sizes listed are TOTAL CAPACITIES. The EFFECTIVE CAPACITES vary depending on tank dimensions & quantity, size & position of fittings so please contact us for clarification.

Manufacturing to Australian Standards

All components of Rhino Water Tanks comply with and surpass all applicable Australian and Industry Standards. The design of all Rhino Water Tanks is certified by the renowned Van Der Meer engineering consultants.

Wall Profile

Corrugated Profile
Our range of corrugated water tanks are manufactured from genuine BlueScope COLORBOND® or ZINCALUME® steel. The wall structure is composed of corrugated CUSTOM BLUE ORB® sheeting that is rolled and curved by our custom made rollforming equipment. The corrugated profile provides increased wall strength and durability.


All Rhino commercial corrugated water tanks can be specifically engineered for cyclonic regions in accordance with Australian Standards for wind loads AS/NZS1170:2007 (Structural Design Action).


The roof structures of all Rhino Commercial Tanks carry dead and live loads in accordance with AS/NZS 1170:2007 (Structural Design Actions).

Rhino Water Tanks sources and supplies high tensile corrugated CUSTOM ORB® sheeting used in the roof of all corrugated tanks. The roof truss system uses Square Hollow Section top cord with structural angle and flat bar plate components to complement a tank designed for all climatic conditions. All trusses are Hot Dipped Galvanised.

Certified design is in accordance with AS 4100 (Steel Structures) and AS/NZS 4600 (Cold Formed Steel Structures).


All welding and other manufacturing involved in the production of Rhino Tanks is in accordance with AS/NZS 1554:2008 (Structural Steel Welding).

Corrosion Protection

All structural components of the Rhino Commercial Tank are hot dipped galvanized to meet AS/NZS 4680:2006 (Hot Dip Galvanized [Zinc] Coatings on Fabricated Ferrous Articles). Every Rhino Water Tank installed uses Sacrificial Magnesium Anodes that are engineered to AS 2239 alloy M3 analysis & performance standard.

The Zinc or Galvanized coating on any steel gives some cathodic protection; however, this protection is limited. The use of Sacrificial Anodes becomes the first defence against corrosion and the Galvanized or Zinc coating on the wall sheets become the second defence. Correct installation and our regular maintenance program are therefore imperative to maximise your tank longevity and design life.


Generally, nozzles used on Rhino Commercial Tanks are manufactured from PE80 HDPE or hot dipped galvanized steel. HDPE fittings are manufactured from PE complying with AS/NZS 4130:2003 and fabricated in accordance with PMBWELD301A.

Nozzles used may be project specific depending on requirements. Larger outlet sizes and other fittings such as Cam Lock, Stortz, CFA and CFS fire couplings can also be provided if required.

Platforms & Ladders

All Platforms and caged ladders on or around Rhino Commercial Tanks are manufactured in accordance with AS 1657-1992 (Fixed Platforms, Walkways, Stairways and Ladders).

Rhino Tank Colours

Rhino Water Tanks can be supplied in ZINCALUME®, Galvanised or a full range of COLORBOND® steel colours as displayed in the chart below. Click on a swatch to see the Rhino change its colour.

Ring Beam Preparation

All commercial water storage tanks require construction on a concrete ring beam footing. It is imperative for the client to ensure foundations and civil works for the site are adequate. Ring beam design is dependent on tank size and location. Appropriate design specification drawings are supplied by Rhino at the time of order.


Rhino Water Tanks has a network of specially trained tank installers across Australia. Our installers focus on quality and excellent service to ensure the job is manufactured, supplied and installed to the customer's specific requirements.

All Rhino tanks are transported to site in flat pack form and then assembled on site. This allows us to position the fittings to the customer's individual requirements and gives us the ability to install tanks on sites with reduced accessibility. Most of our commercial tanks are assembled with the use of cranes as demonstrated in these photos.
