SIMEC spiral steel silo adopts Double-Seam technology, it is particularly suitable for storage of all kinds of bulk materials, to name just a few, grain, soya, feed pellet, biomass pellet, silage fodder, etc. SIMEC spiral steel silos provide high level of stability and total leak-tightness which protect bulk materials from moisture. The smooth internal walls of the silos are a benefit that pays dividends when storing special media.

Construction process of SIMEC spiral steel silo is a combination of technology and wisdom. It applies the principle of plastic working metal hardening and thin shell structure, which make the silo beautiful in appearance, large in capacity while small in area, maximizing economic benefits.

Generally here are 6 steps to build a spiral steel silo:

1. Decoiling

Body of the silo is composed of galvanized steel strip, which was coiled before being transported to the site. The first step to build the silo is to decoil the steel strip.

2. Forming

Decoiled steel strip will be conveyed to the forming machine then. The forming process is to bend the steel strip to a certain radian that was calculated according to the design for storage requirement.

3. Seaminng

The core step to build a spiral steel silo is seaming. SIMEC adopts state of the art double seaming technology to make rugged and stable silo. During the seaming process, silo structure keeps rising, support bearings are taken to shore up the silo construction.

4. Roof Installation

When the height of the silo rises to about 2 meters, the roof will be mounted considering the staff security. After installation of the roof, decoiling, bending and seaming will be continued.

5. Stiffeners Fixing

Accompany with the rising silo, steel stiffeners are used to prevent collapse, the stiffener plates will also enhance the service life of silo.

6. Auxiliary Equipment Installation

A complete silo will always comprise auxiliary equipment. SIMEC consummate the spiral steel silo by inspection glasses, gates, stairways, ladders, platforms, connection pipes, manholes, etc.
