Certificate of structural steel and reinforcing bars for concrete

AENOR accredits the certification of structural steel products such as profiles, bars, sheets or other steel products, in order to ensure the quality and sustainable commitment of these products.

Steel products for concrete

The AENOR N Mark certifies compliance with the requirements applicable to steel products for concrete, guaranteeing compliance with the Structural Code approved by Royal Decree 470/2021, of June 29, as well as with the voluntary requirements defined by the technical conditions included in the Officially Recognized Quality Distinction (DCOR) which grant the products obtained a superior level of quality.

Structural steel profiles, bars and sheets

The AENOR N Mark for hot-rolled steel profiles, bars and sheets for structural applications certifies the product quality according to national UNE or European EN standards

Hollow steel profiles

The AENOR N Mark for structural and non-structural hollow steel profiles aims to ensure compliance with the relevant product standards, thus guaranteeing customer satisfaction.

What do AENOR certificates for steel mean in the context of the structural code?

AENOR product certification is an essential tool for raising the quality of products, since the sale of certified steel offers the consumer greater confidence in the product they purchase and facilitates its sale and introduction into new markets.
