CELSA Group obtains the certification «AENOR N Sustainable” for processed products


  • AENOR has certified the five Celsa Group plants that carry out steel transformation activity in Spain, such as rebar (steel “skeletons” for reinforced concrete structures), wire drawing, electrowelded meshes, basic reinforcements, and also wires and prestressed concrete cords.

  • This certification is in addition to the one already obtained last year by CELSA Group for all its steel mills in Spain.

  • CELSA Group stands out for its sustainable and circular steel production model, based on recycling and reducing emissions by nine times thanks to the use of electric arc furnaces.


Barcelona, 13 March 2023.- AENOR has granted the ‘Aenor N Sustainable ‘ certification to CELSA Group for the processed products it manufactures in its five steel processing plants, which are Celsa Steel Service Illescas, Celsa Steel Service Castellbisbal, Celsa Steel Service Dos Hermanas, Construction Steels and Global Special Steel Products Tycsa.

The certification reflects CELSA Group’s commitment to sustainability, also in this branch of activity, according to AENOR. Already last year, the company received the Aenor N Sustainable certification for all its steel mills in Spain, in which it was the first time that Aenor certified companies and activities in the steel sector with this brand of sustainability.

The group’s factories now recognized with this sustainability certification are responsible for the production of highly specialized processed products from steel. Thus, the three Celsa Steel Service plants manufacture rebar, that is, the steel “skeletons” for reinforced structures that are used in all types of construction such as buildings, infrastructures, etc. In Aceros Para la Construcción they are responsible for producing drawn steel products, electrowelded meshes and basic reinforcements, while Global Special Steel Products Tycsa makes wires and beads for prestressed.

The AENOR N Sustainable seal supports that a product is sustainable from an environmental, social and governance (ESG) approach, so it reinforces and enhances the steel sector’s commitment to sustainability with the reduction of carbon dioxide (CO2) emissions per tonne of steel produced, and promotes essential aspects demanded by society such as social impact and governance, according to AENOR.

With the AENOR Sustainable N Mark certification, it will also be possible to check the evolution of these companies, since year after year it is renewed, which motivates an effort of continuous improvement, detail from AENOR.
