Pressed Steel Tanks

Pressed steel water storage tanks also known as panel tanks or sectional tanks are constructed with hydraulically pressed flanged panels, conform to BS 1564: 1975 and SS22: 1979. Our Panel tanks / Pressed steel tanks are manufactured and installed as per our clients requirements while still conforming to the standards listed above.  Pressed steel tanks offer heavy duty long term liquid storage solutions. These panel steel water storage tanks can be assembled at ground level or they can be elevated on structural steel towers.  Panel tanks that are raised above the ground have the tank stand as an integral part of the design.  

Water Bladder Tanks

Our Water Bladder Tanks are manufactured with the highest safety standards using the latest technology, proven over the last 20 years. Water Bladder Tanks are used in Agriculture, Manufacturing, UN Aid, domestic and Rapid deployment.  The application for the bladder water storage tanks dictates the use with or without a berm liner for secondary containment. A water bladder tank operates in a vacuum, therefore what you put into a water bladder tank is also exactly what you get out of a water bladder tank. Zero dust, air or light exposure to your product.

Fuel Bladder Tanks

Fuel bladder tanks are made in a full military specification also known as Pillow tanks. Fuel bladder tanks are collapsible, flexible storage bladders (also known as tanks) that provide temporary or long term storage for industrial liquids. Our High end fuel bladder tanks are made of elastomer coated fabrics manufactured by homogeneous vulcanization in one operation. Fuel bladder tanks can come equipped with all the necessary components for transportation, for example water transportation or fuel transportation on vehicles.

Corrugated Zinc Dams

Corrugated zinc dams also known as Corrugated reservoirs offer medium to long term water storage solutions. The corrugated reservoir is constructed using galvanized corrugated sheets.  The corrugated reservoir offer a medium weight to structure ratio when compared to other reservoirs.  PVC liners are available in 600, 750 and 1000 micron depending on application.  Corrugated Reservoirs are commonly used in agriculture and mining as they offer a strong and simple solution to liquid storage.

Bio Tank
Bio- and Methane Gas storage

There are various membranes which may be used, ranging from simple stand-alone bladder tanks, to more sophisticated constructions, PVC ground sheets with dome  on a concrete slab or part of a fixed silo. FTS- Flexitank Systems manufactures to any engineer specified drawing. This membrane moves up or downward depending on the filling level. In the case of a dome structure the gas holder with base plate and bottom membrane seals the storage space to the concrete foundation. With the help of the anchoring ring, the membranes are attached to the foundation. Particular emphasis is on the dimensioning of the membranes. 

Each holder will be calculated individually in consideration of the loads (internal pressure, wind and snow loads). As a result, membranes with high tensile strength are selected. The PVC-coated membranes are flame retardant according to DIN 4102 B1, fungicide, and equipped with an increased UV protection.
