Construction products detail
Special metallic materials
The construction products described here are components made of metallic materials with special properties in comparison to commonly used materials of the same type. The construction techniques described here are structural works or parts thereof assembled from these components. Please note that certain material categories, such as stainless steels, are addressed in separate pages.
The special properties may relate, amongst other things, to the chemical composition or the mechanical properties (e.g. yield strength, impact strength, Z-quality). They may also relate to properties that are relevant for processing and/or application (e.g. suitability for cold forming, durability, surface quality).
Metallic materials with weldability as a special property are usually addressed under Welded metal components
Regulatory framework
DIBt grants national technical approvals (abZ) for components (construction products) made of metallic materials with special properties, when the product
- is not covered by a harmonised standard (which is usually the case because of the special properties),
- deviates significantly from the Technical Building Rules (cf. MVV TB, Chapter C 2) or
- when neither Technical Building Rules nor generally recognised technical rules exist for the product.
European Technical Assessments (ETAs) can also be issued for these construction products.
Furthermore, DIBt grants general construction technique permits (aBG) for applications comprising components (construction products) made of metallic materials with special properties for which there are no conclusive technical rules regarding design and execution.
A European Assessment Document (EAD) adopted jointly by the European Technical Assessment Bodies (TABs) is required as a basis for issuing ETAs. If there is no EAD fully covering the construction product when the ETA is being requested, DIBt can develop one or amend an existing one.
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.
