Construction products detail

Welded fabric

Welded fabric and steel wire mesh products are prefabricated reinforcements consisting of longitudinal and transverse wires welded together. They are used to reinforce slab-shaped concrete members. Welded fabric can be laid faster than rebar.

The approval area only concerns welded fabric in which the reinforcing steel deviates significantly from DIN 488, e.g., in terms of rib geometry.

Regulatory framework

DIBt grants national technical approvals (abZ) for products

  • that significantly deviate from the Technical Building Rules (cf., in particular, MVV TB, Part C or
  • for which neither Technical Building Rules nor generally recognised technical rules exist.

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

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).

Please feel free to use the template 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.
