Engineering Advantage
Why Heritage Steel Silos?
From superior materials to precision manufacturing, here is what sets our silos apart from the competition.
- Galvalume & Zincalume Sheet Metal
We exclusively use cutting-edge Galvalume (GI) and Zincalume (ZA) coated sheet metal in all our silos, providing outstanding long-term corrosion protection in every climate.
High Yield Strength Stiffeners
Galvanised steel stiffeners reduce overall silo weight for easier assembly while optimising structural behaviour against wind, seismic, and grain-load forces.
Wave Design Wall Sheets
The gentle-radius wave design provides greater structural strength and improved silo cleaning, ensuring materials unload without residue or contamination.
CNC-Profiled Wall Panels
Side wall panels are processed on dedicated CNC machines. Pitch and depth of corrugations are precisely calculated to maximise load-bearing strength.
Grade 8.8–10.9 HDG Bolts
High-tensile bolts with hot-dip galvanisation coating of 40–50 micron average thickness are used on all silos, meeting international galvanisation standards.
31° Sloped Conical Roof
A cylindrical body with a 31-degree sloped conical roof safely stores grains, seeds, and palletized products while ensuring efficient rainwater run-off and load distribution.
International Compliance

Manufacturing
Process & Technology
A series of precise manufacturing steps ensures every Heritage Steel silo meets the highest structural integrity standards.
DESIGN & ENGINEERING
Flat Bottom Silos are designed as per storage capacity, site condition, grain type, loading system, and unloading requirement. The structure is engineered to provide high strength, long-term stability, and safe storage performance
SILO DESIGN CONSIDERS
Stored Material Characteristics Bulk density Wind load and seismic load Hopper/sweep discharge system Aeration and temperature monitoring (where applicable) Foundation and structural stability
MATERIAL SELECTION
High-strength galvanized structural steel manufactured to applicable project specifications. The material provides excellent corrosion resistance, weather protection, and long service life.
SHEET CORRUGATION & FABRICATION
Steel sheets are corrugated, CNC punching and precision roll-forming wherever applicable. This process gives extra strength to the silo panels and ensures accurate fitting during installation.
SILO ASSEMBLY
The silo panels are assembled ring-wise with high-quality nuts, bolts, stiffeners, and accessories. The flat bottom structure is installed on a strong concrete foundation for stable and permanent storage. Loading and Unloading System
Safe & Secure Packaging
All components are carefully packed using pallets, crates, wooden boxes, and stands, ensuring safe delivery to project sites worldwide.
On-Site Execution
Installation Process
With over 8,000 successful installations, our project team handles and commissions any silo project in any environment.
QUALITY CONTROL
Every component is checked for size accuracy, strength, finishing, and fitting quality before dispatch. This ensures easy installation, safe operation, and reliable performance

- Bolt and fastener
- inspection Coating
- thickness verification (if applicable)
- Final installation inspection
TECHNOLOGY ADVANTAGE
Advanced manufacturing technology and precision engineering ensure reliable performance, reduced grain losses and long-term operational efficiency
Post-Installation Assurance
Silos are assembled using high-quality sealants and high-tensile bolts. Hydro-testing is performed after the roof segment and each subsequent ring to ensure optimal structural performance and watertight integrity.
Our on-site project team provides comprehensive training to the client’s operations staff, designed to promote cost-effective operation and maintenance throughout the full lifespan of the silo.
Goal posts for overhead conveyor structures, ancillary equipment, and all accessories are commissioned as the final stage before formal project handover and client sign-off.
