Overground GRP Tanks

Overground tanks

Overground polyester tanks

We manufacture overground tanks, of any length and diameter, to cover all the requirements of industries, water treatment plants, desalination plants, hotels, houses, etc.

We have a wide range of tanks; horizontal or vertical, with a flat base, with legs, with a skirted base, as well as a wide variety of stairs and railings, to cover all company requirements.

All tanks are calculated in accordance with the European EN-13121 standard, but we can also design them according to other standards (ASME, API, etc.) upon request.

GRP (fibreglass reinforced plastic) is a very suitable material for outdoor use, as it does not corrode. All tanks have an external layer of polyurethane paint with high resistance to the effects of sunlight (UV).

In addition to the standard water tanks, they can be designed and manufactured to contain any other product.
