Glass fused to steel storage tanks for bulk materials that do not form a vault are made of GLS shell and roof. The lower part forms a supporting structure with a conical steel hopper, protected by paint.

The glass-fused to steel bolted hopper can also be fitted into the support structure. In the hopper there are ripper boxes for smoothly storing the magazine. The load-bearing structure is underground for the possibility of picking up directly in the tank.

Trays can be assembled into batteries. Conveying is done by pneumatic or mechanical conveyors. The pick-up is done gravitationally from a conical hopper to a pick-up conveyor or directly to mobile tanks.

If the stack height is not required, the glass-fused to steel shell is mounted on a concrete base and the hopper is hunged in the shell.
