All About Our GRP Covers

Here at Precolor Tank Division, we are a family run business with many years working in the water industry. We offer high quality water storage tanks, specialising in the field of water and chemical storage and are considered market leaders on our industry. Today we’re going to focus our attention to our GRP covers.

What is GRP?

GRP stands for ‘glass reinforced plastic’ and is also known as glass fibre reinforced plastic (GFRP). It is a fibre reinforced polymer consisting of a plastic matrix reinforced by fine fibres of glass. The material is lightweight, yet extremely strong and robust.

What are the benefits of GRP?

As well as being lightweight, strong, and robust, GRP has the added benefit of being less stiff and much less brittle than carbon fibre. Furthermore, the bulk strength and weight properties make them a favourable option in comparison to traditional alternatives made from metal. In addition, GRP can be easily moulded into a variety of designs, making it possible to create standardised duplicates, as well as original designs for bespoke applications. They are also weatherproof, making the material ideal for outdoor use.

What are GRP Covers?

When it comes to GRP covers, there are various options including heavy duty, large span and odour control. With these covers, it is also possible to add some optional features. Examples of this include pump access hatches and ladders, non-slip surfaces, handrails, walkways, full locking facilities, anti-vandal features, and removable panels.  Full odour containment is also made possible with the use of the correct sealant.
