Silo is a vertical tank used for storage of various bulk materials and substances. Silo is cylindrical tank with conic bottom. Vertical position of a silo provides considerable space saving despite impressive amount of raw stock. One more significant advantage of the silo over regular warehouses is provision of high level of protection of stored raw materials from impact of environment (humidity, rain, snow).

Our company offers complex supply and installation of silos, as well as individual performance of the services including: designing, production, installation of thermal insulation and heating, delivery, supply of processing equipment and assembly.

Designing and production of silos is performed according to the regulatory documents in force. Designing is performed on individual basis for every Customer.

Our specialists can help you to choose the optimal design variant, taking into account all wishes, can offer the functional and least-cost solution.

Design of steel silo

The silo is a vertical cylindrical or rectangular tank with flat or conic bottom with an opening (window) and a flat roof. Usually silos with the conic bottom have diameter from 2,5 m to 11 m and height from 5,5 m to 28 m. Silos with flat bottom are made with diameter from 5,5 m to 27,5 m and height up to 33 m.

The rectangular form is used seldom, generally in asphalt concrete production and for storage of fertilizers.

There also forwarding silos: their capacity is smaller and they are used for unloading of stored product to trucks and railway transport.

Usually silos with SMK conic bottoms have small capacity and they are used for short-term storage of products in comparison with silos with SMP flat bottoms.

Silo roof is a structure assembled from stiffeners and trapezoidal sectors. They are connected by means of screws and polymer sealing gaskets.

Production of steel silos

Metal structures for silo frames can be manufactured by two methods: plate-by-plate method and rolling method depending on tank capacity. All elements of silos are made from steel sheets 0,8-12 mm thick depending on capacity and diameter. Steel sheets are connected by means of welding or bolts. The way of fastening of elements should provide the maximum air-tightness of entire metal structure of the silo.

Our enterprise produces silos with capacity from 5 m3 to 1000 m3.

The method of production and structure of silos is chosen on the basis of estimated performance, load capacity of the structure and Customers wishes. Dead load, weight of stored material, wind and snow loadings and seismic conditions are also taken into account. Silos are equipped with stiffeners from corrugate steel sheets in order to ensure vertical stability of the structure (according to Recommendations for reinforcement and repair of building structures of engineering facilities).
