ROSTFREI™ Steels Pvt. Ltd.

offers Grain Storage Systems which consist of grain storage silos, material handling equipment, monitoring systems, aeration systems, and automation systems.

All these grain bins are designed and manufactured to serve for a long period of time without any hassle.

Dynamic analysis of the silo structural system is done according to the seismic and soil conditions of the area where the silos will be installed.

Snow load is calculated according to the conditions of the area where the silos will be installed.

Wind load is calculated according to the height of the silo especially for the empty case of silo.

Static and dynamic analysis of the silo is done for the case of 25? C temperature change.

Static and dynamic analysis of the silo is done according to the vertical and horizontal load of grain.

After the designing with CAD-CAM programs, the silos are manufactured with CNC controlled machines.

FLAT BOTTOM SILOS

For Bulk & Long Time Dry Storage

Flat bottom grain silos are designed and constructed in accordance with ASTM A: 653 and have analysis certificates.

For any kind of large port facilities, our verified product line and proven experience will provide you value well beyond the purchase.

With unrivaled levels of expertise and experience, Rostfrei Steels meet the outstanding challenge in the agricultural industry.

Flat bottom Silos are constructed with a flat bottom surface and are designed by advanced technology and can withstand all types of material storage.

For any type of grain storage above 500MT capacities, flat bottom silos are recommended.

The corrugated, performed, silos panels are assembled cylindrically on circular purlins and vertical stiffeners with bolts and nuts on the heavy concrete rings with deep civil foundations constructed at the site to suit the size of the grain silos.

All the necessary accessories are also provided.

In addition, a sweep auger is also fixed inside the flat concrete bottom for easy discharge outlets with valves.

A sloped roof with manholes, roof ladder and handrails is also constructed at the top of the cylindrical side wall assembled.

The necessary inside and outside ladders with guards are also provided.

There are certain distinct advantages in using corrugated Zinc aluminum sheet panels instead of corrugated galvanized steel panels for building the silos.

Alternatively, there is another option which is Hopper bottom grain silos.

Characteristics of Flat Bottom Silos

Dynamic Analysis of silo structural stability is carried out considering the seismic zone and wind loads of respective areas where the silos will be installed.

Snow load is calculated according to the conditions of the area where the silos will be installed.

Wind load is calculated according to the height of the silo especially for the empty case of the flat bottom grain silo.

High quality and extremely strong materials are used during the production process of the silos.

Zincalume steel sheets are used in the manufacturing of the silos, which are able to withstand strength 350MPa.

Zincalume steel has alloy coating of zinc, aluminium, and silicon carried out at 600-degree centigrade which provides much superior corrosion resistance properties, besides special resin coating and passivation is also done to improve scratch resistant properties.

The standard GI Silos of G-140 (450gr/m2) zinc coating and G-115 (350gr/m2) zinc coating may also be provided according to the customer’s request.

HOPPER BOTTOM SILOS

Hopper Bottom Silos are generally built on fabricated steel structures with the conical bottom made of steel plates and the corrugated sheets performed are assembled with bolts and nuts on circular purlins and vertical stiffeners with waterproof washers, cylindrically above the conical hopper with a sloped roof in the top. Ladders to climb and get into the silos, handrails, manholes etc are provided.

The grains will be discharged by gravity to the bucket elevator/belt conveyor for onward conveying.

These silos can also be built on the top of the concrete conical hopper with beams and columns built in situ.

Aeration, ventilation, temperature monitoring system as required are all provided to the built hopper bottom silos.

Normally these steel silos are recommended for storage up to 500 tones of grains like paddy having the density of less than 550kg/m3.

Alternatively, there is another option which is flat bottom grain silos.

Characteristics of Hopper Bottom Silos

Hopper Bottom Silos are multipurpose and are suitable for grain processing plants, animal feed plants, grain milling plants, and poultry houses.

Hopper Bottom Silos are manufactured in capacities from 20 Tons to 1000 Tons.

Rostfrei offers hopper bottom silos in diameters from 2.74m to 12.79m

Dynamic Analysis of silo structural stability is carried out considering the seismic zone and wind loads of respective areas where the silos will be installed.

Zincalume steels sheets are used in the manufacturing of the silos, which are able to withstand strength 350Mpa.

Standard angle for bottom hopper of a silo is 45 degrees.

However, the bottom hoppers of angle 50, 55, 60 degrees may also be manufactured on request.
