National Structural Steelwork Specification

The 6th Edition of the National Structural Steelwork Specification for Building Construction (NSSS) has now been released.

The NSSS is the national standard for specifying structural steelwork for use in building. The 6th edition supersedes the 5th edition (CE Marking version) of the NSSS and tender documentation and construction contracts should be changed to reference the 6th edition of the NSSS for the steelwork specification.

The 6th edition can be used for all types of building construction designed for static loading and is based on Execution Class 2 structural steelwork designed in accordance with BS 5950-1 or BS EN 1993-1-1 (including BS EN 1993-1-8 and BS EN 1993-1-10) and executed in accordance with BS EN 1090-1 and BS EN 1090-2.
