In the supply chain systems of mining operations, port bulk terminals, and smelters, the efficient storage and safe management of iron ore are critical to ensuring production continuity. Due to iron ore’s high bulk density (typically 2.2–3.0 T/m³), high dust content, and susceptibility to wind and rain erosion, traditional open-air stockpiles are rapidly being replaced by enclosed, high-strength pre-engineered steel iron ore storage warehouses.
With their large-span, column-free spaces, ultra-high load-bearing capacity, and exceptional corrosion resistance and dust suppression capabilities, pre-engineered steel iron ore storage warehouses have become the solution of choice for global mining and logistics giants seeking to build green mines and smart ports:
- Column-Free, Large-Span Spaces
Precast steel structures (such as space frame structures or large-span portal frames) can easily create column-free, ultra-large spaces ranging from 30 meters to over 90 meters, significantly improving the volume ratio and space utilization of iron ore stockpiles.
The column-free, large-span design provides unobstructed access for stacker-reclaimers, loaders, and grab cranes to operate freely, significantly improving the efficiency of bulk cargo handling and turnover.
- Stable Structural Performance
Iron ore stockpiles exert enormous vertical pressure and lateral thrust on the ground and surrounding retaining walls. Through professional load simulation using PKPM/3D3S, the structural design integrates the steel columns with the retaining walls to optimize load-bearing capacity, thereby resolving the long-standing issue of lateral walls being unable to withstand loads and requiring protective measures.
Combined with high-quality welding and high-strength bolted joints compliant with the AWS D1.1 standard, the warehouse can easily withstand winds of Force 12 or higher and high-intensity earthquakes, while also supporting roof-mounted dust suppression sprinkler systems and heavy-duty belt conveyors. Within the same space, the stockpile and mechanical equipment are seamlessly integrated via a conveying system with the port terminals and smelting workshops.
- High Corrosion and Wear Resistance
Hot-dip galvanizing and Duplex dual corrosion protection: To address high salt fog environments in ports or high-humidity conditions in mining areas, components are treated with hot-dip galvanizing (ASTM A123 / ISO 1461, with a thickness of up to 85 micrometers) or a “hot-dip galvanizing + anti-corrosion topcoat” dual protection system to prevent acid and alkali corrosion from mineral powder.
In areas where steel columns and retaining walls are prone to direct impact or friction from ore, high-strength wear-resistant liners or impact-resistant protective barriers are installed to extend the structure’s service life and reduce operating costs.
- Enclosed Structure, Environmentally Friendly
Prefabricated warehouses are fully enclosed with high-strength colored profiled steel sheets or high-quality sandwich panels, completely eliminating dust pollution and soil erosion associated with open-air storage yards.
More than 70% of the steel structural components are precision-cut using CNC laser technology and prefabricated in the factory; they are then rapidly assembled on-site. The construction process is dust-free and low-noise, and the materials are environmentally friendly and recyclable throughout their entire lifecycle.
