There are two types of ZINCALUME® steel. If you must get a rainwater tank in this material, then ensure you get the most recent generation. “Next Generation” ZINCALUME® steel (AM125) launched in August 2013 and lasts longer than older ZINCALUME® steel (AZ150). Both are normally used in roofing, but can be found in steel tanks. […]

It is not true that all poly tanks are the same. Rotathene® poly provides a much higher level of protection against the Sun than the required industry standard for poly tanks. This is how it received its name “SUPA UV”. Rotathene® SUPA UV provides superior protection for rotomoulded products by incorporating advanced additive technology well […]

Stainless steel, also known as inox steel, will not readily corrode, rust or stain from water contact and moisture. The strength and durability of stainless steel makes it a desirable, yet it is also significantly more expensive option. Due to its expense it is normally used in products where both the strength of steel and […]

Polyethylene is one of the most popular water tank materials today for many good reasons. Some main benefits include: poly tanks are strong, light-weight and more cost effective than alternative materials the flexibility of plastic allows for variety of styles and shapes poly tanks are easier to install due to their strength and lightness a […]

Many steel water tanks are made of galvanised steel—a zinc coating that protects the steel from corrosion. These tanks can be built to hold capacities from about 30,000 litres to millions of litres of water making them a suitable solution for extremely large storage requirements. Galvanised steel tanks will rust and corrode over time as […]

Fibreglass tanks are quite rare today, but require a food-grade coating to be up to Australian standards for storing drinkable water. Tanks made of fibreglass are often very stiff and rigid, but relatively thin and light making them quite brittle and prone to cracking. They also allow more light entry and often found in darker […]

Concrete tanks are quite strong and often long lasting. They are generally installed underground for commercial purposes, but can be used for residential use as well. Unfortunately, the introduction of reinforcing steel into concrete has created a new problem that affected the durability of concrete tanks. When embedded reinforced steel can corrode, causing concrete to crack and […]

AQUAPLATE® is BlueScope’s specially constructed steel for rainwater tanks with a 0.2mm polymer layer on at least one side, and normally a painted coating on the outside. This steel is what BlueScope recommend out of all their products for rainwater tanks. AQUAPLATE® which has ZINCFORM® G300S Z275 substrate or the thicker ZINCFORM® G300S Z450 steel layer. The steel […]
