GRP tanks: higher strength, shorter assembly time, cost savings

Despite being made of fibreglass, they are tanks with capacities of up to 15,000 m3. This is achieved thanks to their production process, they have a high content of fibreglass, 70% and 30% resin, when in conventional GRP tanks, the percentages are the inverse. This gives them great mechanical properties. This makes it possible to manufacture slabs up to 11 metres high that are assembled vertically.

In addition, this material has a high chemical resistance, and a high resistance to corrosion, which makes this material more durable than other tanks. Another great advantage is that GRP has a more stable price than steel due to its composition and the materials used for its manufacture, so it saves costs. Moreover, Toro Equipment tanks are modular, that is to say, they are manufactured through plates which allow them to be easily transportable and even allow the tanks to be moved from one place to another.

Other notable advantages of Toro Equipment’s GRP tanks are the following:

• Longer service life.
• Easily transportable due to its lightness and modular composition.
• Easy installation.
• Versatility in shapes and sizes.
• Low thermal conductivity: 0.2107 w/m-K.
• Dielectric material.
• Minimal maintenance and easy to repair.
• Certified for foodstuffs under NSF standards.
• Possibility of burial.
• Wide range of accessories.

They also have 3 different types of plates that have been developed to adapt to each project according to the specific needs of each tank:

• Valladolid plate: it has vertical ribs located on the outside of the plate specially designed to support vertical loads.
• Burgos plate: incorporates polyurethane plates inside the plates for tanks that have to be heat-insulated. Up to 80 mm of PUR can be used, which is equivalent to the same insulation as 160 mm of rock wool.
• Salamanca plate: for general purpose tanks.

Toro Equipment has three types of covers, adapted to the requirements of each project, from the best known flat and conical covers, to its hypar cover with a hyperbolic paraboloid shape reminiscent of the Oceanogràfic in Valencia. In addition, it offers the opportunity to add wall fittings to incorporate a membrane or gasometer.

The installation of the modular GRP tanks requires the creation of a slab for their correct installation. On the other hand, depending on the size of the tank and the conditions of the installation site (wind, earthquake), it may require a groove to fit the plate and baseboard on the outside. One of the great advantages of these tanks is their assembly, being faster than those made of other materials, taking approximately one week to assemble a tank with a capacity of 500 m3.
