TG20:21: Latest Scaffolding Industry Guidance Released

14 Nov, 2021

TG20 provides the definitive guidance for scaffolding constructed with tube and fittings throughout the UK.  TG20 comprises four elements; the Operational Guide, the Design Guide, the User Guide and the NASC’s innovative, user-friendly and widely-adopted eGuide software.

Up until March 2021, this bundle came only in the form of three hard copy guides and a digital download, and was titled TG20:13.  TG20:13 was formally withdrawn, in favour of fully adopting TG20:21, on October 12 2021. Further information can be found here.

Through TG20:21 the guides and eGuide are now available online, with the improved and expanded software and the associated and updated Operational and Design Guides accessible via the NASC ePortal.
