The storage of fire extinguishing water plays a key role in the safety of all buildings and systems. The water supply is usually not sufficient in the event of a fire. In these cases, the authorities often stipulate that a sufficient amount of fire-fighting water must be available. Here is where the specialized water storage tanks come in. Rostfrei Steels is the specialist for fire fighting water tanks. We offer a large selection and favourable prices. The firewater tanks we offer all comply with the latest versions of certifications.
We can offer both underground and above-ground fire water storage tanks in any size, made of steel, stainless steel, plastic, or concrete. New containers are available either factory-made or on-site.
Tank liners prevent the material stored in the tank to keep contact with the tank surface thereby ensuring the stored material to remain contamination free. It does so in the following ways:
Glass Fused Steel tanks (GFS) also called as Glass Lined Steel tanks(GLS) are made by fusing stainless steel and glass. The reason for fusing glass with steel is to enhance the properties of the latter. Single Steel is vulnerable to environmental conditions, hence fusion is required. After fusing the steel with glass, the strength increases, the acceptable bracket of PH value for alkaline solutions widens, and the resistance of abrasion inflates.
We also offer Glass fused steel tanks (Enamel steel tanks) as per the RTP technology and fire protection water storage tanks which meet FM Global & other industry standards.
We complement these services with wide-ranging assistance in the optimization of the operation of new or rehabilitated water plants, private and government water schemes. We offer industrial liquid storage solutions to be used for various applications like industrial water tanks, starting from concept to commissioning and go the extra mile by holding the hand of the customer till Operations & Maintenance of the bolted tanks. We are reviewed as top-rated bolted steel tanks manufacturers, our in-house manufacturing makes our product more reliable from the quality & maintenance-free perspective.
Bolted Storage Tanks come in various sizes and are suitable for numerous applications like Fire Water Tank, Raw Water Tank, Industrial Liquid Storage Tanks, Bio-Digester Tank, Zincalume Tank, Glass Fused To Steel Tank and RO Tank. Rostfrei Steels is one the leading bolted tank manufacturers and pioneers in manufacturing of storage silos and storage tanks. Rostfrei Steels has completed 8000+ installations successfully globally, adheres to the stringent policies of tank manufacturing worldwide and is accredited to various international bodies for tank manufacturing.
These tanks are used for various application like Fire Water, Raw Water, Drinking Water, Domestic Water and many more. Zincalume steel, the most stringent production standards ensures its superior performance and durability.
On continuous research and development, Zincalume® steel now ensures that it is able to withstand harsh environment for a longer period of time.
A level switch is a sensor that detects the presence of liquids, powder, or granulated materials at a specific location. (It is also referred to as level sensor) For example, when a tank is supplied with liquid, it overflow. In order to prevent overflows, a level switch is to be installed different positions of the tank according to types you selected.
Side Mounted Magnetic Level Switch: Float mounted at one end of rigid rod moves with change in level, magnetic capsule at other end of rod moves accordingly within fixed limits Switch contacts across the face change accordingly.
As the tank fills up the float lifts up due to buoyancy. The other end of the float which is magnetic in nature goes down and during its downward motion, triggers the switch assembly and the contacts get closed, which can be used to operate an alarm or any other audio/visual load
As the name indicates, ultrasonic / level sensors measure distance by using ultrasonic waves. The sensor head emits an ultrasonic wave and receives the wave reflected back from the target. ultrasonic / level sensors measure the distance to the target by measuring the time between the emission and reception.
A radar liquid level sensor is an instrument for measuring the height of a liquid and converting it to an electrical signal. Radar liquid level sensor technology transmits a high frequency electromagnetic wave pulse typically in the microwave spectrum, and receives the wave reflected off a liquid surface.

Pressure Transmitter is a mechanical device that measures the expansive force of a liquid or gaseous sample. Also known as a pressure transducer, this type of sensor is typically composed of a pressure sensitive surface area made of steel, silicon, or other materials depending upon the analyte's composition. Behind these surfaces are electronic components capable of converting the applied force of the sample upon the pressure sensor into an electrical signal.
Pressure sensitive environments such as the gas, petrochemical, laboratory, and pharmaceutical industries often require pressure transmitters to monitor the applied force of liquids and gasses as a value of either Pa or psi. This necessitates the precise integration of pressure transmitters into rapid electrical conversion equipment, to ensure results are accurate and delivered in real-time.
A flow switch is a mechanical instrument that is used to control the flow of air, steam or liquid. Flow switches work by sending trip signals to another device (a pump for example) within the system, telling it to shut off or to turn on, which will further protect it from damage and for cooling circuit protection. Flow switches determine if flow is above or below a certain rate, known as a set point. The set point can either be adjustable or fixed, depending on the specification of the individual instrument. When the set point is reached, the response is often the actuation of an electric circuit. Once tripped, the flow switch stays in its new state until the fall falls below the set point.
Level sensor is a device that is designed to monitor, maintain, and measure liquid (and sometimes solid) levels. Once the liquid level is detected, the sensor converts the perceived data into an electric signal. Point level sensors are designed to indicate whether a liquid has reached a specific point in a container.
Level indicator transmitter is tailored for liquid like sulphur and high temperature naphthol and different chemical combinations. This product with stainless steel armoured welding cable and adopted with special high temperature large diaphragm sensor can be used to measure high temperature, strong viscosity medium and can solve other measuring difficulties in process industry.

Water meters are categorised in to two; Domestic and Bulk. Line size from 15mm(1/2”) to 50mm (2”) are domestic meters and large size meters are Bulk Meters. Water meters are classified as Class A, B. Class B meters are expected to have the capability of measuring at a very low flow rate, compared to class A meters. We have meters having the standards of IS 779, IS 6784, ISO4064 (Three parts), OIML R49 and EEC. Threaded ends with nipples are available up to 50mm water meters. Above 50mm, water meters are generally having flanged end connection.
For remote reading purpose, we have pulse Output facility and AMR/GPRS Meters- A technology which automatically collects metering data and transfers that data to a central database for analysis, History and Record purposes. Detailed water usage data can be collected continuously at regular intervals and can be read remotely via an automated process, with the usage data sent to the utility’s management and uniform water distribution & analysis.
A smart water meter not only measures water flow but uses wireless communication to connect to local or wide area networks, allowing remote location monitoring and infrastructure maintenance through leak detection. Smart water metering systems also enable automatic billing and customer management, including detection and protection against tampering attempts. Smart water meters are battery powered and thus low-power devices play a crucial role in defining system configurations.
