What is the difference between spiral steel silo and bolted silo?

HOME > News
Nowadays, there are different types of steel silo of powder material storage, grain storage and other material storage. Spiral silo and bolted silo are two popular types of steel silo. Why are they stay welcomed among different types of silos?
industrial powder storage silo

Features of spiral steel silo:

1. High strength: The industrial powder tank or silo wall is reinforced by vertical stiffener and occluded by screw beam. It has great strength and good resistance to wind, earthquake and snow.
2. Good sealing function: Crimping and seaming of five-layer spiral steel plates ensures airproof, so our industrial powder storage silo can be used to store construction materials such as cement, gypsum, fly ash and slag, as well as liquids.
3. Small area occupancy: The smallest distance between grain storage silo amounts to 500mm.
4. Short construction period: Advanced automatic construction on site, it takes only 5-6 days for a 1,000 tons industrial powder storage silo.
5. Long service life: the industrial powder storage silo can be used for 25-30 years, achieved by best combination of plates of different thickness for powder storage tank body.
6. Beautiful appearance: The roof is subulate and is not easy to accumulate dust or water. The bin is shining and observable with silvery lines.

Features of bolted steel silo:

1. High precision: the bolted grian storage silo has international advanced equipment and technology guarantees.
2. High automation: the bolted grain storage silo can achieve high automation and mechanisation, high productivity, labor-saving.
3. Wide storage: Our grain storage silo has wide storage. Capacity of single silo up to 15,000 tons,
complete function, meet requirement of various customers.
4. Easy maintenance: the grain storage silo, the standard, interchangeable and universal galvanized steel plates and accessories are convenient for maintenance, easy upgrading of capacity or silo move.
5. Less investment: 20-30% less costs over steel bar concrete silos, greatly saving investment.
