Bolt assembly silo

Bolt assembly type steel silo technology is the most advanced among the silo- building technologies in the modern world. Widely used in the American and European countries, bolt assembly type steel silo takes the largest market share in silo area. The modularized production avoids any human factor damages and increases accuracy, preventing damages to the zinc layer during installation. The sidewall and stiffeners are connected by detachable high strength bolts.

Advantage
1. Large capactiy

Silo roof angle 35 degree, more storing space.Single silo capacity is up to 17000 tons, with comprehensive configurations to meet different customer’s requirements.
2. High accuracy
Complete advanced processing equipment and technology are introduced from USA to effectively ensure working accuracy and reduce damage to galvanized layer.
3. Less residues
External installable stiffeners contribute to less grain residues on silo walls.
4. Detachable and movable
With standardized and modularized production, components and parts have a high standardization and good interchangeability, thus can be partially replaced or completely transferred.

Advantage
1. Good sealing performance
With five layer spiral crimping, the seams are very tight, and the silo is of a good sealing performance and can be used as a fumigating silo.It is also suitable for storing building material such as cement.With seal glue embedded into spiral crimping seams, the spiral silo can store fluid material such as waste water.
2. Small area occupancy
Height and diameter are optional in a wide range. The distance between two silos can be minimized to 500 mm to make the most of available space and residue area occupancy.
3. Long service life
Best sheets match to silo body enables a normal service life up to 20-25 years.
4. Short construction period
Highly mechanized construction of spiral a silos on site, short construction period.

Advantage
1. Thermal insulation
Grain temperature change gradient inside silos is lower than that outside, thus not likely to have condensation of moisture.
2. Safe grain storage
Storing in a low temperature, increases the grain storage stability, keeps the grain quality and prolongs the safe- storage period.
3. Low fabrication cost
With installing an insulation layer (polyurethane froth, rubber sponge, glass fiber ect.) on the outer wall, insulation silo can have a low fabrication cost compared to concrete silo.
