Bulk silos made of plastics

Bulk silos made of plastics – glass fibre-reinforced polyester resin (UP-GF) or polyethylene (PE) – are vertical cylindrical containers with funnel-shaped bottom outlets. They are used, e.g., for storing feed or road salt. They are erected on steel supporting frames or skirt supports. Depending on the design, their filling volume can be up to 500 m³.

Regulatory framework

DIBt grants national technical approvals (abZ) for bulk silos made of plastics, usually in combination with a general construction technique permit (aBG) for the application.

Application forms

National procedure

A national technical approval (abZ) and/or oder general construction technique permit (aBG) is granted upon application (see Model Building Code (MBO), Sections 16a(2) and18(2) and (4)). This also applies to amendments and supplements to, or renewals of existing approvals and/or construction technique permits.

No formal requirements apply.
