Spiral vs. bolted steel silos: which is better for your needs?
Steel silos are critical for efficient storage of grains, powders (cement, fly ash, gypsum) and other bulk materials. In their most popular designs, spiral steel silos and bolted silos each offer unique advantages. Let’s compare their features, benefits and ideal applications to help you make an informed decision.
Spiral steel silos: strength and sealing
Spiral silos are constructed using continuous spiral winding technology and are ideal for heavy-duty industrial applications.
Key features and benefits
1.Unrivaled strength
Reinforced with vertical reinforcement and spiral beams for outstanding resistance to wind, vibration and snow.
Ideal for harsh climates and large capacity storage (up to 50,000 tons).
2.100% airtight seal
Five layers of rolled edge steel panels prevent moisture/air ingress, ideal for cement, fly ash, slag and liquid storage.
3.Space saving design
Minimal footprint (500 mm silo spacing) for compact industrial sites.
4.Rapid installation
Automated on-site construction, a 1000-ton silo can be completed in 5-6 days.
5.25-30 year service life
Customized steel plate thickness and hot-dipped galvanized components prevent corrosion.
6.Low maintenance and aesthetics
Sloped roof prevents dust/water accumulation; smooth silver finish.
7.Bolted steel silos: flexible and cost-effective
Bolted silos are modular and expandable using pre-fabricated galvanized steel sheets assembled on site.
Key features and benefits
1.Precision engineering
Manufactured using ISO certified equipment for consistent quality.
2.Easy to expand and relocate
Interchangeable panels allow for rapid capacity upgrades or silo relocation.
3.Highly automated
Compatible with smart sensors and automatic loading/unloading systems.
4.Large capacity options
Individual silo capacities of over 15,000 tons for grain, feed or biomass.
5.30% cost savings
More economical than concrete silos, with a faster return on investment.
6.Low maintenance costs
Galvanized steel resists rust; parts are easy to replace.
