What Is A GRP Water Tank?

GRP stands for Glass Reinforced Plastic, or it is sometimes called Fibre Reinforced Polymer, or FRP. GRP is a type of strong sturdy plastic, and it has many benefits when it comes to storing cold water. Some of these benefits include:

1.      It Is Corrosion Resistant

GRP is one of the best materials you can use when it comes to protection against the weather and is incredibly resistant to both hot and cold weather.

As GRP waters tanks are made of reinforced plastic, they are highly resistant to corrosive materials and can withstand a lot of liquid and rainfall.

Other, metal cold water storage tanks, like tanks made from aluminium or steel, have very low corrosion resistance, and can easily start to rust and wear away after exposure to extreme weather.

2.      Great Weight To Strength Ratio

GRP has a great weight to strength ratio. The glass-reinforced plastic is a strong and sturdy material that can carry a large amount and withstand a lot of pressure without any serious damage. On top of this, it is also very light and easy to transport and manoeuvre, whereas other heavy-duty water storage tanks like steel can be very heavy or aluminium can be light, but not very strong.

3.       Water Tanks Last For A Long Time

GPR water tanks have a long life and can last up to around 25 years. This is because they are made of durable, non-corrosive materials that are designed to stand the test of time. With a GRP water storage tank, you can be sure that your cold water storage tank won’t bevel or break after years of use.

What Is a Steel Water Tank?

A steel cold water storage tank is made from steel a highly durable metal. Steel cold water storage tanks have a lot of great benefits when it comes to using them as your main source of water storage, here are some of the benefits:

1.      Steel Is An Incredibly Durable Material

Steel is one of the strongest possible materials you can have when it comes to cold water storage tanks. It is a good, strong, hardy material that can withstand great heat and extreme cold temperatures. It is very unlikely that it will crack or split, meaning you don’t have to worry about putting too much pressure on the material.

Unlike materials like plastic, steel doesn’t massively change shape or expand in heat, so you don’t have to worry about the change in the structure creating strain or worsening any cracks or scuffs that might appear. Even if a slight scuff or nick does occur on the steel, the metal will not be affected by water or heat, so you do not have to worry about it warming.

2.      Steel Is Incredibly Hygienic

Steel water storage tanks are known for being incredibly hygienic and because of this a lot of care facilities like hospitals choose to use steel water tanks for their cold water storage. Because steel is so watertight, it is very unlikely that anything can get in to contaminate it.

3.      Steel Is An Eco-Friendly Alternative

Unlike plastic, steel can be recycled and used again so by using a steel cold water storage tank you are helping save the planet. It’s important that we try and focus on sustainability and using a steel cold water storage tank is a great way to do this.
