Grain & Feed Steel Silo

Grain & Feed Steel Silo

Our grain and feed steel silos are pre‑fabricated storage solutions for bulk grains, wheat, corn, rice, soybean meal and compound feed. Made of high‑quality galvanized corrugated steel panels with bolt‑assembly structure, the silos feature excellent corrosion resistance and tight sealing, which effectively prevent moisture, mildew and pest infestation to keep materials in good condition.

Available in hopper‑bottom and flat‑bottom designs with customizable capacities. Widely used in feed mills, grain processing plants, breeding farms and grain depots. Optional supporting systems include ventilation, temperature monitoring, dedusting and conveying equipment for automatic storage operation.

Compared with concrete silos, our steel silos save land space, shorten installation time and require low maintenance cost. We provide one‑stop service covering design, manufacturing, on‑site installation and after‑sales support, delivering reliable storage solutions for global clients under various climate conditions.

We also supply steel silos for raw grain storage for grain and feed projects, with single‑silo capacity ranging from 200T to 10000T. We focus on delivering comprehensive solutions for grain and feed processing workflows.
