Description of the system. Glass-fused steel tanks An alternative for storing liquids is the vitreous steel reservoir tank. Here are some of the reasons why customers choose this type of tanks:

  • are modular;
  • available in several sizes, with capacities ranging from 50 m3 to 25000 m3;
  • customizable design according to customer specifications;
  • maintenance that tends to “0” during use due to the removal of the inner membrane;
  • fast construction with minimal impact on the environment;


The roof of the tank

The roof is a rigid structure made of lightweight polyurethane panels placed on the galvanized Z-section of metal beams made of S350GD Z275 material according to SR EN 10147: 2001 and SR EN 10143: 2001. Polyurethane panels are mounted on “Z” “Through an overlapping system to achieve sealing of the roof. This roof panel assembly eliminates the possibility of infesting the volume of water with dust and impurities from the atmosphere. The upper edge of the tank is protected by mounting a corner profile (mask) made of galvanized sheet.

NOTE: Each roof is calculated according to the climatic characteristics of the site.

Depending on the destination of the tank (potable water, biogas, purification station, etc.), several types of roofs can be used:

  • Flat roof;
  • Conical roof;
  • Roof “house” type;
  • No roof;

Thermal insulation of the tank. Insulation of fire protection storage tank can be done on the outside, with mineral wool, protected from the outside with cut sheet. In this case, where the thermal insulation of the tank is arranged externally, the inner membrane can be removed; the stored liquid is in direct contact with the tank casing. The sealing of the reservoir plates is made by special mastic.

In the case of inner insulation, the walls of the tank are insulated with 50 mm thick polystyrene panels fixed between the vitrified steel panels and the membrane. The way the membrane attaches to the edge of the tank, as well as the sealing roof, does not allow the water to contact the insulation.

Use of fused steel tanks with glass. The vitrified steel screens are ideal for the following uses:

  • Drinking water storage: Due to the integration into space (urban or rural), glass-fired steel tanks become an option for urban and not only urban projects where capacities between 50m3 and 25,000m3 are needed;
  • Process water storage: vitrified steel tanks are required where rust contamination and durability are important. Because a surface that has to last for a long time without the need for interventions, only vitrified steel can be an option;
  • Wastewater storage: When choosing a wastewater storage tank, taking into account durability and total life-cycle costs, vitrified steel tanks are perfect for use as aerators, balancing and cleaning tanks;
  • Biofuels and anaerobic digesters: With long experience and remarkable results, vitrified steel tanks have proven to be able to deliver the performance of stainless steel but at much lower costs;
  • Suspended tanks: The only thing more disturbing than spending money on repainting a tank is to have to repaint a tank 30 meters high. Fortunately, a vitrified steel tank is not dyed and does not need repainting, maintenance costs close to “0”;

By performing scheduled maintenance and maintenance, we continuously monitor the operation of our installations, thereby ensuring their continued operation. After verification of the characteristics of the objective, the conditions for safe operation and efficiency are established, and the optimal mechanical technology is determined to take into account the value of the expenses.

About the preparation and construction of water tanks for fire cases and reservoirs for other liquids and wells, we carry out complete design and realization. Read this.

Placement on site

We transport the tanks according to size and location, in one or more units, to permit the circulation of larger capacity vehicles, the tanks’ parts will be transported on the spot with smaller vanes as special lengths.

Location of hydrants

Firewater tank: To store the amount of water required when extinguishing the fire, an underground pool or above the ground must be provided. The amount of fire-fighting water shall be determined according to the norms set by law, and partly depending on the operating parameters of the fire-extinguishing system, unless the authorities determine other conditions.
