NASC ePortal

The definitive guidance for the scaffolding industry including the new TG30™ for system scaffolding and TG20™ for tube and fitting scaffolding. TG20™ and TG30™ have been produced by NASC, in response to the introduction of BS EN 12811. They provide generally recognised standard configurations for tube and fitting and system scaffolding, as required by The Work at Height Regulations 2005, which have been designed by structural calculation and for which additional bespoke design is not required.
