Hot-rolled

Structural steel

The guaranteed strength and good weldability of our hot-rolled structural steel help ensure ease of processing and reliable end-product performance.

As with all our hot-rolled steel products, our structural steel is manufactured under tight controls – for consistent quality that you can depend on.

Overview

Availability

Structural steel products are available as follows:

  • As-rolled (+AR)

  • Normalised rolling (+N)

  • Suitable for cold forming (C)

  • Suitable for post-galvanising (Class 1)

  • Weathering steel (W)

Relationship with standards

Hot-rolled structural steel complies with European standard EN 10025: 2004 and is available in the grades shown in the table below.

If normalised rolling (+N) or cold forming (C) is required, please specify when ordering. In these cases, this should be indicated by adding the relevant letter to the grade at the time of ordering (for example: S355J0C+AR). Cold forming cannot be guaranteed for structural steel that is not specified as cold-formable.

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 Performance (DoP). All the structural products produced by Tata Steel in Europe are CE-marked except for S185+AR.
