It can be used as temporarily warehouses, transit, warehouses, materials warehouses and grain storage. Bolted silo has the following advantages: a. Less basic cost with lightweight, low request for foundation, low consumption of steel. b. High degree of standardization. Our company can produce the standard components to realize the standard, common, series according to the user's requirements. c. Simply installation with short period. Because all components are connected by standard bolts. d. Realize mechanization easily. The bolted silo is equipped with relevant auxiliaries' parts, such as: conveyor, ventilation, drying and monitoring device to ensure the quality and safety of the stored grain. e. Maintain easily.
