GRP tank technology is now accepted as standard in virtually every industry from chemicals to food and water, microelectronics and offshore oil and gas. The available sizes for these standard tanks is from 5000 to 160,000 litres capacity and from 2000 to 4111mm internal diameter (to suit standard mandrels)
Forbes are able to manufacture this range of GRP storage tanks using a variety of different specification materials selected for the appropriate chemical resistance.
We will always endeavour to recommend the most cost effective solution to your requirements.
Filament winding manufacturing techniques do not produce the ideal glass/resin ratio for process plant applications therefore, Forbes invested in a massive installation for the production of cylindrical GRP shells by the ?chop-hoop? winding process.
Automated controls constantly monitor the rate of deposition of both glass and resin and provide detailed quality records. The laminate is particularly strong and economical and combines the advantages of winding and spraying techniques, notably considerable multidirectional strength and enhanced inter-laminar shear when compared to filament winding.
All Forbes GRP tank products are designed and constructed to comply with BS4994:1987 - THE DESIGN AND CONSTRUCTION OF VESSELS AND TANKS IN GLASS REINFORCED PLASTICS
BS4994 covers the design, manufacture, transport and installation of tanks and vessels in GRP (glass fibre reinforced plastic) materials. It is a very thorough and stringent standard but DOES NOT cover any aspect of the manufacture of tanks in other materials such as metals or freestanding thermoplastics.
Where necessary, tanks will be post-cured in accordance with the resin manufacturers specifications to ensure optimum physical and chemical properties in order to achieve maximum performance from the laminates.
Our massive post-curing oven, fitted with a calibrated chart recorder, is over 5 metres in diameter and 13 metres long. It is capable of sustaining temperatures in excess of 100 0C over long periods.

A superb standard range of high performance silos made from glass reinforced plastics (GRP) using up-to-the-minute 'chop hoop' filament winding technology.
Very strong and light, these silos are completely corrosion-free and will give many years of service without maintenance. All steelwork is hot-dip galvanised.
As the UK's leading manufacturer of standard GRP silos, Forbes experience is unrivalled.
Forbes glassfibre silos can be produced in a variety of high performance resin and glass systems to meet the most exacting requirements.
Typical applications include sugar, PVD salt, animal feeds, fertilisers, soap nodules and flaked chemicals - although the standard silo design can be adapted to suit practically any bulk product application.
Forbes silos have an innovative filling system which allows fast, uniform loading and complete filling to specified capacity. The special design of the system can help to reduce particle separation and dust generation in some applications.
The translucent wall of the silos allows contents to be checked at a glance from ground level against the integral calibration markings.
