How to specify Advance

To make it easier to specify Advance sections from Corus we have developed a simplified naming protocol for both material specification and section designation.

 

  

Section designation

Steel specification


The standard method for specifying the dimensions of a standard hot rolled steel section includes using initials to designate the type of section, for example: 457x191x67UB, is a Universal Beam of nominal dimensions 457mm deep, 191mm wide, weighing 67Kg/m. Because CE marking is not mandatory in the UK, it is technically feasible for, e.g. a Universal Beam to be supplied in the UK that is not CE marked. We have therefore introduced a change to the section dimension designation system for our Advance section range, which guarantees that products supplied by Corus, using the new designation system, will comply with CE mark requirements. The table below shows the new section designation system for Advance sections from Corus.

The UK prefix to each of the new designations simply identifies that it is a section from the Advance range of sections manufactured for the UK market by Corus, which is guaranteed to be CE marked. It is also a guarantee that the sections supplied will carry the many other benefits of naming Corus as the supplier

Example – 457x191x67UB becomes 457x191x67UKB

All the Advance structural steel sections are supplied in accordance with the Standards indicated in the table below.

Even if this designation system is used it does not guarantee that a CE marked product will be supplied in the UK.

However, using the new simplified designation system for AdvanceTM sections from Corus, for example;

Advance275JR

 guarantees that the product supplied will meet all the requirements of EN10025:Part2:2004 and that it will be CE marked.
