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

While poly water tanks are one of the most popular tank choices, it is important to consider that not all poly tanks are the same. Australia has one of the highest levels of UV radiation in the world with over 200 kilolangleys of UV radiation annually, double that of SE Asia, Europe and most of […]

One of the most popular tank choices today are polyethylene (poly) water tanks. Poly water tanks can last a long time, up to 20 years or more. The material can withstand the harsh effects of the Sun due to UV-stabilisers added to the moulding mix. These stabilisers inhibit or absorb the harmful UV light preventing […]

Until recent decades, the most common material for rainwater tanks seen in the Australian outback were corrugated steel tanks. These tanks were often galvanised, which is a process where a protective zinc alloy is applied to iron in order to provide an electrochemical protection against rust and corrosion. Galvanised steel is found in many products […]

Fibreglass water tanks (Glass Fibre Reinforced Plastic) can be found on the market for storing rainwater. They are often comprised of a resin, mixed with a hardener with glass fibres that are sprayed into a mould. A food-grade coating exists on their interior surface so that they can safely store drinkable rainwater. The fibreglass material […]

Concrete rainwater tanks are expensive, but ideal for underground water storage or when large quantities of water need storing. They are often long lasting, although cracking will eventually happen over time depending upon the strength of concrete and level of reinforced with steel. One benefit, but also disadvantage, is the lime that is found in […]

Until recent decades, a common material for steel roofs, sheds and rainwater tanks the littered the Australian outback were galvanised iron – steel that has a zinc coating to provide protection against rust and corrosion. Prior to 1976 many steel roofs were also galvanised. Then BHP Steel (now BlueScope Steel) developed and launched ZINCALUME® steel […]

Prior to 1970’s many steel roofs were large galvanised. Then a Chicago-based company, Lithostrip Corporation and Pre Finish Metals, discovered a way to successfully bond paint to a galvanised base. John Lysaght brought the technology into Australia and invested much time and effort getting the process right. This resulted in COLORBOND® steel being rolled out […]
