TG20 provides the definitive guidance for scaffolding constructed with tube and fittings throughout the UK. TG20:21 builds on TG20:13, and makes the eGuide software, Design Guide and Operational Guide available via the new NASC ePortal, on a subscription basis.
The eGuide produces pdf compliance sheets, which now include more information and an illustration. The guides are fully searchable online.
The ePortal is available here from computers, tablets and smart phones via web browsers. Each subscription gives access from multiple machines, but only one machine at a time.
Purchase and use of a subscription implies acceptance of the subscription agreement, found here, by all users.

This guidance explains the differences between ‘supplementary’ and ‘check’ couplers and gives typical design applications where high coupler forces could be expected and where additional loadbearing capacity to connections may be required. It also contains guidance on coupler configurations and expected safe working loads (SWLs) where supplementary couplers are used. To ensure that SWL values are as accurate as possible, data provided within this document is based on practical testing rather than calculation.
The TG20 Operational Guide contains detailed practical guidance for most common types of scaffolding, supported by structural research and calculation. Guidance is provided for a range of standard structures which includes independent scaffolding, interior birdcages, chimney stack scaffolds, loading bays, ladder-access towers, free-standing towers, lift shaft towers, putlog scaffolding, exterior birdcages, tube and fitting mobile towers, tube and fitting loading bays without beams, and tied independent scaffolds with three inside boards.
NASC members can purchase 10 or more copies of the TG20:21 Operational Guide book at the discounted rate of £25 per unit. To do so, please email email@example.com
This guidance identifies the specification and test requirements and minimum markings to be found on all EN74-1 scaffold fittings. The 2015 update sees no change other than dates. EN74-1 is unlikely to change in the next four years.
Scaffold board nailplates are specially stamped toothed strips of galvanised steel that can be applied to new or used boards to prevent or to repair existing end splits. Experience gained over many years by the scaffold industry indicates that the service life of a board can be substantially extended if nailplates are fitted. This revised and updated version contains additional information and guidance on the specification and fitting of nailplates.
