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.
The price shown includes VAT at 20%.
If you are already using TG20:21 and wish to continue to use the same login details please do not purchase a new subscription, please purchase a subscription renewal here.

Aluminium tubes, prefabricated beams and other components are widely used throughout the scaffolding industry. Whilst aluminium is not as stiff as steel and will deflect more when subjected to equivalent loads, it is much lighter and provides great advantages with regard to manual handling or the reduction weight. As aluminium couplers are not readily available, aluminium tube and beams are invariably connected with steel couplers and joint pins. Unfortunately, when two dissimilar metals such as aluminium and steel are in contact, a phenomenon known as ‘galvanic corrosion’ can occur where the corrosion of one of the metals, in this case aluminium, can be greatly accelerated. In severe cases this could seriously affect the integrity of the scaffold structure.
In an ideal world all working platforms should contain no gaps or holes. This updated guidance is a simplification of the previous 2003 issue regarding working platforms, which have additional requirements over those that are normally provided on an access scaffold. Quality and the thickness of ply used are integral. 4 pages
Many free-standing scaffolding structures, such as access towers, major signboards, fences and enclosures, need to be anchored to the ground, primarily to resist wind forces. Whilst all structures requiring restraint via anchoring to the ground should be subject to a bespoke design produced by a competent engineer, the guidance considers different types of anchors available and typical indicative holding capacities, the possibility of disturbing underground services, the use of guys and scaffold tube restraint. 6 pages
A temporary roof or building is a sheeted structure designed to protect the area inside from the effects of weather, dust, etc. This guide is intended to give design and construction information to the suppliers and erectors of temporary roofs and buildings and intended for use by contractors during the building process. 56 pages
