1 Light steel frame (LSF) technology is widely utilised throughout the UK construction industry and LSFA (Light Steel Frame Association) members have demonstrated that the construction method is a durable, highly efficient alternative to traditional construction methods. Whilst light steel frame systems are often seen as innovative or as a modern method of construction, they are actually a proven, established method with high levels of certification, backed-up by rigorous testing.

The new document outlines the certifications that can be obtained to validate system performance, the type of testing required and sets guidelines to help both those manufacturing and specifying systems. It has been deliberately set as a high-level overview and is intended to point the reader to places where further information is available. As a proven and well-established offsite manufactured technology, light steel frame is trusted and widely

used throughout the UK across all construction sectors however, this document covers residential and commercial bedspace only. The type of certification selected for LSF technology is determined by the type of system, the sector in which it is being used and the design parameters of the structures. Validation is provided by a variety of organisations, who carry out an assessment of the build system. There are numerous types of providers, and
