Spiral Folded Silo

Spiral Silo Information

The construction technique of spiral folded silo is the most advanced technology in the world. Its construction method is unique. The patent technology of double profiling steel silos formerly belongs to West Germany. Double profiling is the technical feature.
It is popularized widely used doe below advantages:

• Integral Intensity And Long Life.

  While constructing, feed the coil sheet with certain width into the profiling station, making an confined encircling spiral protruding strip of 30-40mm in width around the silo body. The thickness of the strip is five times thicker than the basic coil sheet, strengthen the silo body in load-bearing capacity, also strengthen the silo in the structure.

• Good Gas-tightness And Wide Application.

  The spiral folded edge is of five-layer spiral steel plates with seal gum embedded into spiral crimping seams which ensures excellent silo gas-tightness. The spiral folded silo can store granular, powder material, also meet the requirements of fumigation and deinsectization. Besides, it can also store liquid material, for two kinds of different material, the silo construction equipment can realize double layer bending.

• Short Construction Cycle And Low Expenses.

  As the silo is manufactured full auto by the special equipment which runs at speed of 300m/h, the construction of the silo is very fast, and investment returns fast.

• Economizing On Space And Light Weight.

  The silo height and diameter is optional with a wide range. The distance between two silos can be minimized to 500mm to make the most of available space and reduce area occupancy. Also the weight of the silo is only 1/6 times of the concrete silo with the same capacity, largely reduce the base structural load and cost.
