This document provides guidance for covering 50mm gaps in scaffold platforms through which standards protrude, as well as for covering larger gaps in decking which, due to width restrictions or obstructions, cannot be fully boarded in the conventional way.
This guidance is PDF only.
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.
A 32-page, full-colour pocket guide in A6 format. This document summarises clearly the requirements for TG20:21 compliant scaffolding and offers indispensable guidance to the scaffolding operative on-site. Price is £9.50 per copy for non-NASC members and £4.75 per copy for NASC members. Members wishing to place an order for 100+ copies must email sales@nasc.org.uk as further discounts apply.
This document provides best practice for the use and application of steel and aluminium prefabricated beams. Included is information regarding beam types, uses, joints, handling, transportation and storage. Due to the wide variation of beams available on the market, it has not been possible to include individual load capacities, but information regarding tension and compression chords, correct methods of lacing, bracing and connections to standards and puncheons provides vital information to ensure that beams are correctly installed to support their maximum safe working loads. This guidance is available for pdf download only.
The TG20 Design Guide provides technical data, commentary, and source material for use by competent and suitably qualified scaffold designers in circumstances which are outside the scope of standard solutions provided in the TG20 Operational Guide and TG20 e-Guide software. NASC members can purchase 10 or more copies of the TG20:21 Design Guide book at the discounted rate of £25 per unit. To do so, please email sales@nasc.org.uk
