The full‑cone‑bottom steel grain silo, developed by Zhengzhou Wangu Machinery, is a modern bulk‑material storage solution tailored for grain processing plants, feed mills, distilleries and grain‑trade storage centers. It enables long‑term safe storage of granular and powdery materials including wheat, corn, rice, soybeans, sorghum, wheat bran, soybean meal, distiller’s grains and germ. It effectively blocks moisture and pests, stabilizes material quality and cuts storage loss.

The silo body adopts a modular corrugated steel plate bolt‑assembled structure. Single‑silo standalone operation and multi‑silo cluster layout are both available to meet the warehousing requirements for continuous factory production. Compared with conventional concrete warehouses, steel silos occupy less land, feature shorter construction cycles and good compatibility with automation systems. Hot‑dip galvanized anti‑corrosion treatment and well‑optimized structural stress guarantee stable and durable outdoor service.

Key Features

Hermetic & Leak-Free: double-layer aviation rubber strip sealing - zero rainwater leakage, zero fumigation gas escape - keeps grain dry and free from pest infestation.

Corrosion & Rust Resistant: hot-dip galvanized corrugated steel panels resist corrosion and rust, slow aging, with 25-40 year design life.

Modular Installation: bolted assembly, no large lifting equipment needed, quick to install, and relocatable to a new site and re-erected.

Flexible Capacity: cone-bottom silos from 20-2715 t (diameter φ4.6-12.8 m, 4-18 rings adjustable), flat-bottom silos from 800-10000 t, with 90+ spec combinations to choose from.

Safe Monitoring: equipped with grain temperature monitoring and audible/visual alarm systems to track stored grain in real time and detect heating faults early.

Full-Scene Application: pairs with intake, discharge, cleaning, drying and weighing equipment to form a complete grain storage system.

Application Fields

This prefabricated steel silo is widely used in grain processing, oil production, feed manufacturing, distilling, grain‑oil trading and agricultural cooperatives. It stores raw grains such as corn, wheat, rice, soybeans and sorghum, as well as grain‑oil by‑products including soybean meal, wheat bran, corn fiber, distiller’s grains, germ and rapeseed pellets. Each silo is hermetically independent, isolating materials from external contaminants. Optional accessories such as ventilation ducts, on‑line temperature sensors, arch‑breaking devices and dust‑removal equipment can be configured according to material properties. This ensures stable storage for materials of varying moisture content, reduces storage loss and secures steady raw‑material supply for production workshops.

Packaging & Quality Assurance

Each steel silo is shipped disassembled and packed, with core parts such as corrugated panels and bolts protected against moisture and impact, meeting both sea and land transport requirements. Standard packaging is reinforced to prevent damage during handling; customized packaging can also be arranged on request. All equipment is produced under the ISO quality management system and fully tested and adjusted before shipment. We offer a 12-month warranty covering the main frame and key components, along with online technical support, installation guidance and on-hand spare parts supply. Minimum trial order is 1 set. Payment via T/T deposit or L/C at sight. Share your required storage capacity and the grain type to be stored - we will recommend the most suitable specification and provide a competitive quotation.
