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

To prepare an abZ/aBG for your construction product, we need an application from you. We recommend that you contact us prior to doing so. Feel free to send us your enquiry informally via email to dibt(at)dibt(.)de or to the competent technical contact listed in the top right.

For a first assessment, please send us the following information:

  • Description of the construction product and its intended field of use
    • e.g. material, configuration, number of sizes, variants, dimensions
    • e.g. use in walls, ceilings, interior construction, building services
  • Description of the construction technique and its field of application
    • e.g. design of walls, ceilings, elements, etc., and interaction of components
    • e.g. application in foundation engineering, reinforced concrete construction, building insulation; as load-bearing or non-load-bearing component; under static and quasi-static loading; fire exposure; other environmental exposures
  • Information regarding impact on regulatory concerns
    • in particular structural integrity, fire protection, health and environment protection, sound insulation as well as thermal performance
  • Explanation of need for an abZ/aBG
  • Contact details
    • preferably email address and/or telephone number, as well as name, organisation/company, and postal address

We will then contact you to clarify the next steps.

If you already hold a DIBt approval and/or construction technique permit and wish to apply for an amendment, supplement, or renewal, please use the form provided below.

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.
