Product Overview

   The Steel Grain Silo is the core product of Wangu Machinery's storage system. It adopts hot-dip galvanized corrugated steel plate with bolted assembly technology, enabling large-scale, safe, and long-term grain storage. The silo body is assembled on-site with bolted hot-dip galvanized corrugated steel plates — no welding required, excellent sealing, fast installation, and relocatable. Two series are available: hopper bottom silo (20–2,715t) and flat bottom silo (800–10,000t), with diameters from φ4.6 to φ12.8m and 90+ size combinations, covering all scenarios from grain procurement stations to national strategic reserves.

 Primary Applications

   The Steel Grain Silo is designed for large-scale safe grain storage after harvest. It solves critical post-harvest challenges of dampness, mold, rodent damage, and theft from open-air storage, ensuring commercial grain meets quality standards for safe storage and orderly discharge.
