Grain storage silos are widely used in the agricultural industry to store and preserve grains such as wheat, corn, rice, barley, oats, and soybeans. The storage needs of farmers, agricultural cooperatives, and grain processing facilities.   Rostfrei silos features There are two types of grain silos : Hopper bottom & flat bottom Hopper bottom silos range from capacities of 20 metric ton  to 1000 metric ton Flat bottom silos range from capacity of 50 MT to 15,000 MT. Diameters ranging from 4.57 meters to 36.54 meters Our silos are designed as per standards : Ansi / Asae 2008 & ss EN1993-4-1:2011 All our silos model go through structure stability test & design calculations have been vetted by a government authorised IIT Lab Rostfrei silos are designed to stand up to strong winds of 250 kmph, & in seismic zone-4 Rostfrei silos roof are supported by rafters & supports. We give s shaped rafters with z shaped crossing to make high strength structure Zincalume steel of our silos are coated with specially developed passivation and resin coating as separate layers that makes it scratch resistant Rostfrei steels silos undergo structure stability analysis tests & all silos designs are vetted by government authorised labs   Aeration & ventilation system Aeration, ventilation and fumigation are sized properly in rostfrei silos so that the environment inside the silo can be controlled to maintain topmost grain quality.   Purpose of aeration : Remove excess heat & moisture from grain Maintain uniform temperature in every area of grain inside the silo to stop moisture migration & hot-spot development Reducing fungi, insect growth & discolouration of paddy Removing odours from grain Air flow of aeration fans are selected based on silo volume and type of grain being stored Vents and roof exhausters are sized to 2.5 times the flow of all aeration fans put together   Anti-condensation Unit Humidity sensors are given at the topmost Part of silos to detect humid air/ Moisture movement from the grains. Roof exhausters receive input from sensors and expel out excessive humid air out of the silo so that no condensation / Spoilage of grains occur   Fumigation system Most insects enter grain silos from the top and stay there within 1-2 meters for weeks. Fungi are already present in paddy at the time of harvest and grow rapidly at temperature 20 to 40 degrees and moisture more than 14% Fumigation is a most essential activity for safe storage of grain inside silo. Hence rostfrei silos are properly designed to carry out effective fumigation Rostfrei steels uses closed loop fumigation system in grain silos for effective fumigation using phosphine gas. Closed loop fumigation system consists of gas fan, upvc pipes, inlet outlet valves and electronic gas monitors. In process, phosphine gas concentration levels are made to  reach and be maintained at 300 parts per million (PPM) For seven days (When grain is above 25°c). This ensures killing of  grain pests at all stages of their  life cycle Once the fumigation cycle is over, silo must be de-sealed and aeration fans must be kept running until the phosphine levels drop down to 0.3PPM We size the fumigation system in such a way that pressure drops are minimum and fumigation is effectively achieved with proper safety precautions as phosphine gas is explosive when its concentration reach more than 17900 PPM.   Temperature monitoring system Temperature monitoring cables are there to monitor temperature inside the silo. Each sensor is present at every 2.5 meters to monitor grain quality If moisture migration, discolouration, insect infestation, hot-spot occurs, temperture of that area of grain increases by 2-3 degree celcius. Operator is alerted on  plc monitor screen This enables operator to take suitable actions on right time to save grain quality. Action 1: Aerate the grain for adequate time Action 2 : If aeration could not  remove hot-spots, then fumigation of 6-7 days   Rostfrei make material handling equipments Sweep augers rotate 360 degrees around the base of the silo from central motor Unit to push remaining grain towards silo’s discharge gates Rostfrei steels manufactures durable and high quality GI 275 grade elevators and conveyors. These are equipped with all the necessary sensors and safety switches Rostfrei steels specialises in “inception to comissioning” of grain storage & management greenfield turnkey projects.    Timeline of project 5000 MT x 2 maize silo complete by 55 days 250 MT x 2 soyaben silos complete by 30 days Recieveing hoppers by 10 days Cleaner erection and complete arrangement done in 8-10 days Elevator and conveyors in 10-15 days Complete project erection and comissioning within 75 days Dispatch from the date of po issue Will be within 60 days

ROSTFREI STEELS PREFABRICATED Glass Fused Steel Tank (GFS Tank)\\n\\nGlass-Fused-to-Steel (GFS) tanks, also known as Glass Lined Steel (GLS) tanks, represent a premium technology in the tank market. The fusion of glass and high-tensile mild steel combines the best properties of both materials. Steel provides strength and flexibility, while glass offers corrosion resistance. This fusion eliminates the need for painting in the future, as the tank is inherently protected against corrosion by the glass enamel coat. One of the significant advantages of GFS tanks is the widening of the acceptable bracket of pH values after the fusion of steel with glass. This means that the tanks can withstand a wider range of pH levels without compromising their integrity.\\n\\nMoreover, the application of Glass-Fused-to-Steel technology to both interior and exterior surfaces ensures that the tanks can withstand harsh environments for many years without encountering significant issues. This durability makes GFS tanks an excellent choice for various industrial, municipal, and agricultural applications where reliability and longevity are crucial factors.\\n\\nROSTFREI offers two variants of Glass-Fused Steel (GFS) Tanks:\\n1. GFS Tanks with Sealant:  \\n   - These tanks utilize a high-performance sealant to secure joints and seams, providing robust protection against leaks and corrosion.\\n2. GFS Tanks with Liner: \\n   - These tanks come with a specialized internal liner that provides an additional layer of protection, ensuring enhanced durability and corrosion resistance.\\nLiner:  The liner is a protective barrier that shields the tank’s interior from chemical reactions, corrosion, and external contaminants, significantly extending the tank\\\'s service life.\\n\\nAPPLICATIONS OF GLASS FUSED STEEL TANKS\\nGlass Fused Steel Tanks offer extensive applications across various application & industries. Some are mentioned below:\\n\\nEffluent Treatment (ETP) Tanks\\nSewage Treatment (STP) Tanks\\nWater & Wastewater Treatment (WWTP) Tanks\\nZLD (Zero Liquid Discharge)\\nDesalination\\nCondensate Water\\nIrrigation Water\\nPotable Water\\nRO Water\\nRO Reject Water\\nSoft Water\\nFire Water\\nDrinking Water (with NSF 61 certified PVC liner)\\nPotable Water\\nRaw Water\\nFire Water\\nRainwater Collection Tank\\n

Fusion Bond Epoxy Coated Prefabricated (FBE) Tanks are Manufactured by Fusing Epoxy to Preheated Mild steel plates. The reason of fusing epoxy with steel is to enhance the properties of later. Bare Steel is vulnerable to environmental conditions, hence the fusion coating is required. After fusing the steel with epoxy, the resistance against atmospheric weathering & corrosion increases and the acceptable bracket of PH value widens. Epoxy (FBE) Tanks can be used to store wide range of liquids like clear Water, Waste water, Organic waste, Oil etc.   CHARACTERISTICS/BENEFIT OF ROSTFREI FBE TANKS : FBE tank serves for more than 30 years Suitable for potable water & all clear water & sewage water applications Installation process is quick, safe & eco friendly Pre-fabricated design is easily relocatable & extendable, if more capacity required in future New & better technology globally.   PROCESS & TECHNOLOGY : The tank Panels are fused with epoxy coating both inside & outside. The fusion process is carried out in a special furnace having temperature range from 120 to 240 Degree Celsius under controlled environment. The Steel rounded (cylindrical) shell of the tank is built up by overlapping two panels and nut bolting with Special high grade nuts & bolts and constant application of flexible sealant/ Liner. The connecting material and shell accessories are equipped by the various surface protection treatment. The Fusion Bond Epoxy tanks can be used to store fluid or loose material. The tanks are also a fundamental building element of environmental technological facilities such as Waste Water Treatment and Biogas Plants.
