The CE mark

The CE mark is a symbol devised by the European Council to signify that a product meets the conditions of the applicable council directives. These conditions aim to ensure that the product is reliable and safe. Products that are “produced for incorporation in a permanent manner in construction works” fall under the Construction Products Directive. Hot-rolled steels covered by EN 10025: 2004 are used in such “works” and are therefore covered by the directive. For these products, Tata Steel’s test certificates bear the CE mark and Tata Steel has issued a certified Declaration of Conformity. All the structural products produced by Tata Steel in Europe are CE-marked except for S185+AR.

The CE mark

The CE mark is a symbol devised by the European Council to signify that a product meets the conditions of the applicable council directives. These conditions aim to ensure that the product is reliable and safe. Products that are “produced for incorporation in a permanent manner in construction works” fall under the Construction Products Directive. Hot-rolled steels covered by EN 10025: 2004 are used in such “works” and are therefore covered by the directive. For these products, Tata Steel’s test certificates bear the CE mark and Tata Steel has issued a certified Declaration of Conformity. All the structural products produced by Tata Steel in Europe are CE-marked except for S185+AR.

The CE mark

The CE mark is a symbol devised by the European Council to signify that a product meets the conditions of the applicable council directives. These conditions aim to ensure that the product is reliable and safe. Products that are “produced for incorporation in a permanent manner in construction works” fall under the Construction Products Directive. Hot-rolled steels covered by EN 10025: 2004 are used in such “works” and are therefore covered by the directive. For these products, Tata Steel’s test certificates bear the CE mark and Tata Steel has issued a certified Declaration of Conformity. All the structural products produced by Tata Steel in Europe are CE-marked except for S185+AR.
