The spiral silo is profiled by a special silo profile machine. The silo structure is a mechanically integrated whole without holes, bolts and screws.
Substrate: strong anti-corrosion performance by hot galvanized steel sheet 275g/m2, 340g/m3 or 600g/m2, no paint required for life.
Application: Ideal silo for storage of cement, fly ash, mineral powder, water and oil for perfect sealing performance.
Diameter range: 4m-25m
Silo cylinder height range: 6m-25m
spiral silo function
Integral strength and long life
During construction, coil sheets of a certain width are fed to a profiling station to create a limited circular spiral protruding strip 30-40 mm wide around the silo body. The thickness of the strip is 5 times thicker than the basic coil sheet, strengthening the silo body in load-bearing capacity and strengthening the silo of the structure.
Excellent airtightness and wide application
The spiral folded edge is a 5-layer spiral steel plate with sealing rubber embedded in the spiral crimping seam to ensure good silo tightness. The spiral folded silo can store granular powder materials, and meets the requirements of fumigation and pesticide. It can also store liquid materials, and for two kinds of different materials, the silo construction equipment can realize double-layer bending.
Short construction cycle and low cost
The construction of the silo is very fast and the return on investment is very fast because the silo is manufactured fully automatically by special equipment operating at a speed of 300m/h.
Space saving and light weight
Silo heights and diameters are optional over a wide range. The distance between the two silos can be minimized to 500mm, making the most of the available space and reducing the footprint. In addition, the silo weighs only 1/6 of the same capacity concrete silo, which greatly reduces the basic structural load and cost.
