Construction products detail

Non-metallic reinforcement

Glass fibre reinforced plastic (GFRP) rebars are one example of non-metallic rebars. They are serrated to ensure sufficient bonding with the concrete. Reinforcements made of glass fibre reinforced plastic are more corrosion-resistant than reinforcing steel, non-magnetic and electrically insulating. Further advantages of using non-metallic reinforcements are the lower reinforcement weight and the lower required concrete covers.

Regulatory framework

DIBt grants national technical approvals (abZ) for non-metallic reinforcements because no Technical Building Rules nor generally recognised technical rules exist for them.

European Technical Assessments (ETAs) can also be issued upon request.

Furthermore, DIBt grants general construction technique permits (aBG) for construction techniques comprising non-metallic reinforcements, for which there are no conclusive technical rules.

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. The following information is needed: name and address of the applicant, description of the product and/or construction technique and its field of use or application, type of decision required (new decision, amendment or supplement to, or renewal of, an existing decision).

European Technical Assessment (ETA)

To start the ETA procedure, please submit the form below. We will then check if the prerequisites for issuing an ETA are met, i.e., in particular, if the product is not fully covered by an existing harmonised standard. If the prerequisites are met, we will check whether a European Assessment Document (EAD) covering the requested assessment scope already exists or still needs to be developed. If an EAD needs to be developed or amended, a complete technical file needs to be established before the procedure can begin.
